    \title QDoc Manual

    QDoc is the internal tool used by Qt Development Frameworks for generating
    documentation. This document is a reference for QDoc command syntax and
    configuration.

    \section1 Overview

    \list I
    \o \section2 \l {QDoc Commands}

       \l {QDoc Commands - Alphabetical List}{A complete alphabetical
       list}.

       There are two main categories of commands for QDoc: markup
       commands and meta-commands.

       The markup commands indicate the generated documentation's
       appearance and logical structure. The meta-commands provide
       information about the document as well as the documented
       item. The meta-commands can be further categorized as topical
       commands and contextual commands.

       \list
       \o \l {Markup Commands}

           \endlist
       \endlist
    \endlist

    \list II
    \o \section2 \l {QDoc Configuration}

       When running QDoc to generate the documentation, you must
       specify a configuration file on the command line. The
       configuration file is a list of entries of entries of the form
       "variable = value".

       \list
       \o \l {Configuration Variables}
       \o \l {Configuration File Examples}
       \endlist

       Some particular configuration variables allow you to use QDoc
       to support Qt-based projects; i.e to make projects, such as Qt
       Solutions, contain references to the online Qt documentation.

       \list
       \o \l {Supporting Derived Projects}
       \endlist

       QDoc is a tool that constantly evolves to suit our needs, for
       that reason there are some compatibility issues between old and
       new practices.

    There are two main categories of commands for QDoc: markup
    commands and meta-commands.

    The markup commands indicate the generated documentation's visual

    \table
    \header
        \o Command
        \o Description

    \row

        \o \bold \\\\ \target backslash
        \o \bold {The \\\\ command expands to a single backslash.}

           QDoc commands always start with a backslash alone. To
           display an actual backslash in the text you need to type
           two of the kind. If you want to display two backslashes,
           you need to type four, and so forth. For example:

           \code
           / *!
               The \\\\ command is useful if you want a
               backslash to appear verbatim, for example,
               writing C:\\windows\\home\\.
           * /
           \endcode

           will be rendered as

           \quotation
               The \\\\ command is useful if you want a
               backslash to appear verbatim, for example,
               writing C:\\windows\\home\\.
           \endquotation

           However, if you want your text to appear in a typewriter
           font as well, you can use the \l {c}{\\c} command instead,
           which accepts and renders the backslash as any other
           character. For example:

           \code
           / *!
               The \\c command is useful if you want a
               backslash to appear verbatim, and the word
               that contains it written in a typewriter font,
               like this: \c {C:\windows\home\}.
           * /
           \endcode

           will be rendered as

           \quotation
               The \\c command is useful if you want a
               backslash to appear verbatim, and the word
               that contains it written in a typewriter font,
               like this: \c {C:\windows\home\}.
           \endquotation

    \row
        \o \bold \\a \target a
        \o \bold {The \\a command indicates that the next word
           is a parameter when documenting functions.}

           Warnings are emitted when function parameters are
           undocumented or misspelled, so whenever you write
           documentation for functions you should make sure you
           mention all the parameters and precede each of these by the
           \\a command. The parameter is then rendered in italic. For
           example:

           \code
           / *!
               Constructs a line edit containing the text
               \a contents.

               The \a parent parameter is sent to the
               QWidget constructor.
           * /

           QLineEdit::QLineEdit(const QString &contents, QWidget *parent)
               :QWidget(parent)
           {
               ...
           }

           \endcode

           will be rendered as

           \quotation
               \bold {QLineEdit::QLineEdit ( const QString &
               contents, QWidget *parent )}

           Constructs a line edit containing the text \a contents.

           The \a parent parameter is sent to the QWidget
           constructor.

           \endquotation

           The \\a command follows the same conventions as the \l
           {i}{\\i} command for \l {argument}{punctuation, parentheses
           and use of braces} for the argument. However, a parameter
           is always a single word, so braces are rarely
           necessary. And for the same reason, parentheses seldom
           occur.

    \row
        \o \bold \\c \target c
        \o \bold {The \\c command can be used to render variables,
           user-defined classes and C++ keywords like \c int,
           \c for, etc.}

           The command renders its argument using a typewriter font. For
           example:

           \code
           / *!
               The \c AnalogClock class provides a clock widget with hour
               and minute hands that is automatically updated every
               few seconds.
           * /
           \endcode

           will be rendered as

           \quotation
               The \c AnalogClock class provides a clock widget with hour
               and minute hands that is automatically updated every
               few seconds.
           \endquotation

           The \\c command follows the same conventions as the \l
           {i}{\\i} command for \l {argument}{punctuation, parentheses
           and use of braces} for the argument.

           The \\c command accepts the special character \c \ within
           its argument, i.e. it renders it as a normal character. So
           if you want to use nested commands, you must use the \l
           {tt}{teletype (\\tt)} command instead.

           See also \l {tt}{\\tt} and \l {code}{\\code}.

    \row
        \o \bold \\tt \target tt
        \o \bold {The \\tt command can be used to render variables,
           user-defined classes and C++ keywords like \c int, \c
           for, etc.}

           The \\tt command behaves just like the \l {c}{\\c} command,
           except that \\tt parses QDoc commands (like \l {i}{\\i}, \l
           {bold}{\\bold} and \l {underline}{\\underline}) contained
           within its argument.

           The command renders its argument using a monospace
           font. For example:

           \code
           / *!
               After \c setupUi() populates the main container with
               child widgets it scans the main container's list of
               slots for names with the form
               \tt{on_\i{objectName}_\i{signalName}().}
           * /
           \endcode

           will be rendered as

           \quotation
               After \c setupUi() populates the main container with
               child widgets it scans the main container's list of
               slots for names with the form
               \tt{on_\i{objectName}_\i{signalName}().}
           \endquotation

           The \\tt command follows the same conventions as the \l
           {i}{\\i} command for \l {argument}{punctuation, parentheses
           and use of braces} for the argument.

           See also \l {c}{\\c}.

    \row
        \o \bold \\bold \target bold
        \o \bold {The \\bold command renders its argument using
           a bold font.}

           For example:

           \code
           / *!
               This is regular text; \bold {this text is
               rendered using the \\bold command}.
           * /
           \endcode

           will be rendered as

           \quotation
           This is regular text; \bold {this text is rendered using
           the \\bold command}.
           \endquotation

           The command follows the same conventions as the \l {i}{\\i}
           command for \l {argument}{punctuation, parentheses and use
           of braces} for the argument.

    \row
        \o \bold \\i \target i
        \o \bold {The \\i command renders its argument in italic.}

           \warning This is preliminary functionality. For
           more information, see the \l
           {26-qdoc-commands-compatibility.html#i-versus-e}{compatibility}
           section.

           \target argument
           Normally, a command argument ends at the next whitespace [1],
           but braces can be used to group words [2]. For example:

               Here, we render \i {a few words} in italic.

           will be rendered as

           \quotation

           \endquotation

           If you want to use other QDoc commands within an argument
           that contains spaces, you always need to enclose the
           argument with braces. But QDoc is smart enough to count
           parentheses [3], so you don't need braces in cases like this:

           \code
           / *!
               An argument can sometimes contain whitespaces,
               for example: \i QPushButton(tr("A Brand New Button"))
           * /
           \endcode

           will be rendered as

           \quotation
               An argument can sometimes contain whitespaces,
               for example: \i QPushButton(tr("A Brand New Button"))
           \endquotation

           Finally, trailing punctuation is not included in an
           argument [4], nor is 's [5]

    \title Document Structuring Commands

    The document structuring commands divide the documentation into
    sections. In total, there are six levels of sections in QDoc: \c
    \part, \c \chapter, \c \section1, \c \section2, \c \section3 and
    \c \section4. \c \section1 to \c \section4 correspond to the
    traditional section, subsection, subsubsection and
    subsubsubsection.

        \o \bold \\part \target part
        \o \bold {The \\part command is intended for use in
           larger documents, and divides the document into parts.}

           In general a document structuring command considers
           everything that follows it until the first line break as
           its argument. The argument is rendered as the unit's
           title. If the title needs to be spanned over several lines,
           make sure that each line (except the last one) is ended
           with a backslash.

           In total, there are six levels of sections in QDoc: \c
           \part, \c \chapter, \c \section1, \c \section2, \c
           \section3 and \c \section4. \c \section1 to \c \section4
           correspond to the traditional section, subsection,
           subsubsection and subsubsubsection.

           There is a strict ordering of the section units:

           \code
           part
              |
              chapter
                    |
                    section1
                           |
                           section2
                                  |
                                  section3
                                         |
                                         section4
           \endcode

           For example, a \c section1 unit can only appear as the top
           level section or inside a \c chapter unit. Skipping a
           section unit, for example from \c part to \c section1, is
           not allowed.

           You can \i begin with either of the three: \c part, \c
           chapter or \c section1. For example:


           \code
           / *!
               \part Basic Qt

               This is the first part.

    \title Verbatim Code Commands

    The following commands are used to render verbatim code within the
    documentation. The code is rendered on a new line, using a
    typewriter font and the standard indentation.

    \bold{Note:} Although all of these commands can be used to present
    C++ code, the \l{07-0-qdoc-commands-quoting.html#snippet}{\\snippet}
    and \l{07-0-qdoc-commands-quoting.html#codeline}{\\codeline} commands
    should be used in preference to
    the others when presenting valid code. This allows auxilliary tools
    for Qt language bindings to substitute the relevant code snippets in

        \o \bold \\code \target code
        \o \bold {The \\code command and the corresponding
           \\endcode command delimit a piece of verbatim code.}

           Whereas the \l {c}{\\c} command can be used for short code
           fragments within a sentence, the \\code command is for
           longer code snippets and renders the code verbatim in a
           separate paragraph using a typewriter font and the standard
           indentation.

           When processing any of the \\code, \l {badcode}{\\badcode},
           \l {newcode}{\\newcode} and \l {oldcode}{\\oldcode}
           commands, QDoc basically removes all indentation that is
           common for the verbatim code blocks within a \c{/}\c{*!} ...
           \c{*}\c{/} comment before it adds the standard
           indentation. For that reason the recommended style is to
           use 8 spaces for the verbatim code contained within these
           commands (note that this doesn't apply to externally
           quoted code using the \l {quotefromfile}{\\quotefromfile}
           or \l {quotefile}{\\quotefile} command).

           For example:

           \code
           / *!
               \code
                   #include <QApplication>
                   #include <QPushButton>

                   int main(int argc, char *argv[])
                   {
                       ...
                   }
               \ endcode
           * /
           \endcode

           will be rendered as

               #include <QPushButton>

               int main(int argc, char *argv[])
               {
                   ...
               }
           \endcode

           Other QDoc commands are disabled within
           \\code... \\endcode, and the special character '\\' is
           accepted and rendered like the rest of the code.

           You need to type the code manually between the \\code and
           \\endcode commands. If you want to include code snippets
           from a particular file, use the \l
           {07-0-qdoc-commands-quoting.html#quotefromfile}{\\quotefromfile}
           command instead.

           See also \l {c}{\\c}, \l

           compile or is wrong for some other reason.}

           The \\badcode command is similar the \l {code}{\\code}
           command, but renders the code using a grey font instead of
           black (the default).

           Like the \l {code}{\\code} command, it renders its code on
           a new line in the documentation using a typewriter font and
           the standard indentation. For example:

           \code
           / *!
               The statement below is rendered using the
               regular \\code command:

           code to a new version of an API.}

           The \\newcode command, and its companion the \\oldcode
           command, is a convenience combination of the \l
           {code}{\\code} and \l {badcode}{\\badcode} commands: The
           combination provides a text relating the two code snippets
           to each other. The command requires a preceding \\oldcode
           statement.

           Like the \l {code}{\\code} and \l {badcode}{\\badcode}
           commands, the \\newcode command renders its code on a new
           line in the documentation using a typewriter font and the
           standard indentation. For example:

           \endquotation

           Other QDoc commands are disabled within

    \title Quoting External Code Commands

    The following commands enable quoting from files in the
    documentation: You can make QDoc include the complete contents of
    a file, or you can quote specific parts of the file and skip
    others. The typical use of the latter is to quote a file chunk by
    chunk.

    \bold{Note:} Although all of these commands can be used to present
    C++ code, the \l{#snippet}{\\snippet} and \l{#codeline}{\\codeline}
    commands should be used in preference to
    the others when presenting valid code. This allows auxilliary tools
    for Qt language bindings to substitute the relevant code snippets in
    place of the C++ ones.

        \o Description

    \row
        \o \bold \\quotefile \target quotefile
        \o \bold {The \\quotefile command expands to the complete
           contents of the file given as argument.}

           The command considers the rest of the line as part of its
           argument, make sure to follow the file name with a line
           break.

           The file's contents is rendered in a separate paragraph,
           using a typewriter font and the standard indentation. The
           code is shown verbatim.

           For example:

           \code
           / *!
               This is a simple "Hello world" example:

               \quotefile examples/main.cpp

               It contains only the bare minimum you need
               to get a Qt application up and running.
           * /
           \endcode

           will be rendered as

           \quotation
               This is a simple "Hello world" example:

               It contains only the bare minimum you need to get a Qt
               application up and running.
           \endquotation

           \warning If you use the \l {QDoc
           Compatibility}{compat.qdocconf} file this command is called
           \\include.

           See also \l {quotefromfile}{\\quotefromfile} and \l
           {code}{\\code}.

    \row
        \o \bold \\quotefromfile \target quotefromfile
        \o \bold {The \\quotefromfile command opens the file
           given as argument for quoting.}

           The command considers the rest of the line as part of its
           argument, make sure to follow the file name with a line
           break.

           The command is intended for use when quoting parts from
           file with the walkthrough commands: \l
           {printline}{\\printline}, \l {printto}{\\printto}, \l
           {printuntil}{\\printuntil}, \l {skipline}{\\skipline}, \l
           {skipto}{\\skipto}, \l {skipuntil}{\\skipuntil}. This
           enables you to quote specific portions of a file. For
           example:

           \code
           / *!
               The whole application is contained within
               the \c main() function:

               \quotefromfile examples/main.cpp

               \skipto main
               \printuntil app(argc, argv)

               First we create a QApplication object using
               the \c argc and \c argv parameters.

               \skipto QPushButton
               \printuntil resize

               Then we create a QPushButton, and give it a reasonable
               size using the QWidget::resize() function.

               ...
           * /
           \endcode

           will be rendered as

           \quotation
               The whole application is contained within
               the \c main() function:

               \skipto main

               ...
           \endquotation

           (\l {Example File}{The complete example file...})

           QDoc remembers which file it's quoting, and the current
           position within that file (see \l {file}{\\printline} for
           more information). There is no need to "close" the file.

           Earlier we called this command \\quotefile. For more
           information, see the \l
           {26-qdoc-commands-compatibility.html#quotefromfile-versus-quotefile}
           {compatibility} section.

           \l {dots}{\\dots}.

    \row
        \o \bold \\printline \target printline
        \o \bold {The \\printline command expands to the line
           from the current position to the next non-blank line of
           the current souce file.}

           To ensure that the documentation always is synchronized
           with the source file, a substring of the line must be
           specified as an argument to the command. Note that the
           command considers the rest of the line as part of its
           argument, make sure to follow the substring with a line
           break.

           The line from the source file is rendered as a separate
           paragraph, using a typewriter font and the standard
           indentation. The code is shown verbatim.

           For example:

           \code
           / *!
               There has to be exactly one QApplication object
               in every GUI application that uses Qt.

               \quotefromfile examples/main.cpp

               \printline QApplication

               This line includes the QApplication class
               definition. QApplication manages various
               application-wide resources, such as the
               default font and cursor.

               \printline QPushButton

               This line includes the QPushButton class
               definition. The QPushButton widget provides a command
               button.

               \printline main

           \endquotation

           (\l {Example File}{The complete example file...})

           \target file

           QDoc reads the file sequentially. To move the current
           position forward you can use either of the \l
           {skipline}{\\skip...} commands. To move the current
           position backward, you can use the \l
           {quotefromfile}{\\quotefromfile} command again.

           \target substring

           If the substring argument is surrounded by slashes it is
           interpreted as a \l {regular expression}.

           For example:

           \code
           / *!
               \quotefromfile widgets/scribble/mainwindow.cpp

               \skipto closeEvent
               \printuntil /^\}/

               Close events are sent to widgets that the users want to
               close, usually by clicking \c File|Exit or by clicking
               the \c X title bar button. By reimplementing the event
               handler, we can intercept attempts to close the
               application.
           * /
           \endcode

           will be rendered as

           \quotation
               \quotefromfile widgets/scribble/mainwindow.cpp

               \skipto closeEvent
               \printuntil /^\}/

               Close events are sent to widgets that the users want to

               the \c X title bar button. By reimplementing the event
               handler, we can intercept attempts to close the

           \endquotation

           (\l {widgets/scribble}{The complete example file...})

           The regular expression \c /^\}/ makes QDoc print until the
           first '}' character occurring at the beginning of the line
           without indentation. /.../ encloses the regular expression,
           and '^' means the beginning of the line. The '}' character
           must be escaped since it is a special character in regular
           expressions.

           QDoc will emit a warning if the specified substring or
           regular expression cannot be located, i.e. if the source
           code has changed.

           See also \l {printto}{\\printto} and \l

           from the current position up to and \i excluding the
           next line containing a given substring.}

           The command considers the rest of the line as part of its
           argument, make sure to follow the substring with a line
           break. The command also follows the same conventions for \l
           {file}{positioning} and \l {substring}{argument} as the \l
           {printline}{\\printline} command.

           The lines from the source file are rendered in a separate
           paragraph, using a typewriter font and the standard
           indentation. The code is shown verbatim.

           For example:

    \title Linking Commands

    The linking commands make it possible to create hyperlinks to
    classes, functions, header files and examples. They also make it
    possible to link to targets within a document, as well as to other
    documents and URLs.

        \o Description

    \row
        \o \bold \\l \target l
        \o \bold {The \\l command is used to create hyperlinks. }

           The command's general syntax is

           \code
           \l {link target}{link text}
           \endcode

           For example:

           \code
           / *!
               Read the \l {http://qt.nokia.com/doc/4.0/}
               {Qt's Reference Documentation} carefully.
           * /
           \endcode

           will be rendered as

           \quotation
              Read the \l {http://qt.nokia.com/doc/4.0/}
              {Qt's Reference Documentation} carefully.
           \endquotation

           If the link target is equivalent to the link text, the
           second argument can be omitted.

           For example, if you have documentation like:

           \code
           / *!
               \target assertions

               Assertions make some statement about the text at the
               point where they occur in the regexp but they do not
               match any characters.

               ...

               Regexps are built up from expressions, quantifiers, and
               \l {assertions}{assertions}.
           * /
           \endcode

           you can rewrite it as

           \code
           / *!
               \target assertions

               Assertions make some statement about the text at the
               point where they occur in the regexp but they do not
               match any characters.

               ...

               Regexps are built up from expressions, quantifiers, and
               \l assertions.
           * /
           \endcode

           For the one-parameter version the braces can often
           be omitted. See the \l {i}{\\i} command for the \l
           {argument}{argument conventions}.

           The \\l command supports several kinds of links:

           \list
           \o \c {\l QWidget} - a defined \l {class}{\\class}
           \o \c {\l QWidget::sizeHint()} - a defined member
               function (\l {fn}{\\fn})
           \o \c {\l <QtGlobal>} - a defined \l {headerfile}{\\headerfile}
           \o \c {\l widgets/wiggly} - a defined
              \l {example-command}{\\example}
           \o \c {\l {QWidget Class Reference}} - a defined \l {title}{\\title}
           \o \c {\l {Introduction}}- a defined \l{part}{\\part},
              \l{chapter}{\\chapter} or \l {sectionOne}{\\section...}
           \o \c {\l fontmatching} - a defined \l {target}{\\target}
           \o \c {\l {Shared Classes}} - a defined \l {keyword}{\\keyword}
           \o \c {\l network.html} - a defined \l {page}{\\page}
           \o \c {\l http://www.trolltech.com/} - a URL
           \endlist

           QDoc also tries to make a link out of any words that don't
           resemble any normal English words, for example Qt class
           names or functions, like QWidget or QWidget::sizeHint(). In
           these cases, the \\l command can actually be omitted, but
           by using the command, you ensure that QDoc will emit a
           warning if it cannot find the link target. In addition, if
           you only want the function name to appear in the link, you
           can use the following syntax:

           \list
               \o \c {\l {QWidget::}{sizeHint()}}
           \endlist

           See also \l {sa}{\\sa}, \l {target}{\\target} and \l
           {keyword}{\\keyword}.

    \row
        \o \bold \\sa \target sa
        \o \bold {The \\sa command defines a list of links that will
           be rendered in a separate "See also" section at the bottom
           of the documentation.}

           The command takes a comma-separated list of links as its
           argument. If the line ends with a comma, you can continue
           on a second line.  The general syntax is:

           \code
           \sa {the first link}, {the second link},
               {the third link}, ...
           \endcode

           QDoc will automatically try to generate "See also" links
           interconnecting a property's various functions. For
           example, an setVisible() function will automatically get a
           link to visible() and vice versa.

           In general, QDoc will generate "See also" links that
           interconnect the functions that access the same
           property. It recognizes four different syntax versions:

           \list
           \o \c property()
           \o \c setProperty()
           \o \c isProperty()
           \o \c hasProperty()
           \endlist

           The \\sa command supports the same kind
           of links as the \l {l}{\\l} command. For example:

           \code
           / *!
               Appends the actions \a actions to this widget's
               list of actions.

               \sa removeAction(), QMenu, addAction()
           * /
           void QWidget::addActions(QList<QAction *> actions)
           {
           ...
           }
           \endcode

           will be rendered as

           \quotation
               \bold {void QWidget::addActions ( QList<QAction*>
               \i actions )}

               Appends the actions \i actions to this widget's
               list of actions.

               See also \l {QWidget::removeAction()}{removeAction()},
               \l QMenu, and \l {QWidget::addAction()}{addAction()}.
           \endquotation

           See also \l {l}{\\l}, \l {target}{\\target} and \l
           {keyword}{\\keyword}.

    \row
        \o \bold \\target \target target
        \o \bold {The \\target command defines an explicit point in the
           documentation that you can later link to using the \l {l}{\\l}
           and \l {sa}{\\sa} commands.}

           The command considers the rest of the line as part of its
           argument, make sure to follow the target name with a line
           break.

           For example:

           \code
           / *!
               \target capturing parentheses
               \section1 Capturing Text

               Parentheses allow us to group elements together so that
               we can quantify and capture them.

               ...
           * /
           \endcode

           can be referenced with

           \list
           \o \c {\l {capturing parentheses}}
              (from elsewhere in the same comment)
           \o \c {\l qregexp.html#capturing-parentheses}
              (from anywhere else)
           \endlist

           within a documentation unit, and with

           \list
           \o \c {\l http://www.trolltech.com/4.0/doc/html/qregexp.html#capturing-parentheses}
           \endlist

           on a more global scale.

           If the target name does't contain any spaces, the brackets can
           be omitted as well.

           See also \l {l}{\\l}, \l {sa}{\\sa} and \l
           {keyword}{\\keyword}.

    \row
        \o \bold \\keyword \target keyword
        \o \bold {The \\keyword command defines an explicit point in the
           documentation that you can later link to using the \l {l}{\\l}
           and \l {sa}{\\sa} commands.}

           Keywords must be unique within the entire set of
           documentation processed in on QDoc run.  The command
           considers the rest of the line as part of its argument,
           make sure to follow the keyword with a line break.

           The \\keyword command is similar to \l {target}{\\target},
           but stronger.  A keyword can be referenced from anywhere
           using a simple syntax. For example:

           \code
           / *!
               \class QRegExp
               \reentrant
               \brief The QRegExp class provides pattern
                      matching using regular expressions.
               \ingroup tools
               \ingroup misc
               \ingroup shared
               \mainclass

               \keyword regular expression

               Regular expressions, or "regexps", provide a way to
               find patterns within text.

               ...
           * /
           \endcode

           can be referenced like this

           \code
           / *!
               When a string is surrounded by slashes, it's
               interpreted as a \l regular expression.
           * /
           \endcode

           which will be rendered as

           \quotation
               When a string is surrounded by slashes, it's
               interpreted as a \l {regular expression}.
           \endquotation

           If the keyword does't contain any spaces, the brackets can
           be omitted as well.

        \o \bold \\image \target image
        \o \bold {The \\image command expands to the image specified by its
           argument, and renders it centered as a separate paragraph.}

           The \\image command replaces the old \\img command. For more
           information, see the \l
           {26-qdoc-commands-compatibility.html#image-versus-img}
           {compatibility} section.

           The command takes two arguments. The first is the name of
           the image file. The second argument is optional and is a
           simple description of the image equivalent to the HTML
           alt="" in an image tag. The description is used for
           tooltips, and when a browser doesn't support images like
           the Lynx text browser.

           The command considers the rest of the line after the file
           name its second argument, make sure that you follow the
           filename or description with a line break. Braces are only
           necessary if the description spans several lines.

           For example:

           \code
           / *!
               Qt by Trolltech is a C++ toolkit for cross-platform GUI
               application development.

    \title Container Commands

    The container commands create tables and lists with associated
    items and contents. A list is rendered left aligned as a separate
    paragraph. A table is rendered centered as a separate paragraph,
    and its width depends on its content.

   \section1 Alphabetical List

        \o Description

    \row
        \o \bold \\table \target table
        \o \bold {The \\table command and the corresponding \\endtable
           command delimit the contents of a table.}

           The command accepts a single argument specifying the
           table's width in percentage:

           \code
           / *!
               \table 100 %

                  ...

               \endtable
           * /
           \endcode

           The code above ensures that the table will fill all
           available space. If the table's width is smaller than 100 %,
           the table will be centered in the generated documentation.

           A table can contain headers, rows and columns. A row starts
           with a \l {row}{\\row} command and consists of cells, which
           starts with a \l {o}{\\o} command. There is also a \l
           {header}{\\header} command which is a special kind of row
           with a special formatting. For example:

           \code
           / *!

           The background cell color of each row alternate between two

           The documentation will be located in the associated class,

           You need to create each list item explicitly using the \l
           {o}{\\o} command. A list can contain one or more items; it
           can also be nested. For example:

           \code
           / *!
               \list
               \o Qt Reference Documentation: Getting Started

           will be rendered as

               \o Tutorial and Examples
               \endlist
           \endlist

           The \\list command takes an optional argument providing
           alternative appearances for the list items. For example:

           \code
           / *!
               \list
                   \o How to Learn Qt

                   \o Tutorial and Examples
               \endlist
           * /
           \endcode

           will render the list items with bullets (the default):

           \list
               \o How to Learn Qt
               \o Installation
               \o Tutorial and Examples
           \endlist

           If you provide 'A' as an argument to the \\list command,
           the bullets are replaced with characters following in
           alphabetical order:

           \list A
               \o How to Learn Qt
               \o Installation
               \o Tutorial and Examples
           \endlist

           If you replace 'A' with '1', the list items are rendered
           with numbers following in ascending order:

           \list 1
               \o How to Learn Qt
               \o Installation
               \o Tutorial and Examples

           \endlist

           If you provide 'i' as the argument, the default bullets are
           replaced with roman numerals:

           \list i
               \o How to Learn Qt
               \o Installation
               \o Tutorial and Examples
           \endlist

           Or finally, you can make the list items appear with roman
           numbers following in ascending order if you provide 'I' as
           the optional argument:

           \list I
               \o How to Learn Qt
               \o Installation
               \o Tutorial and Examples
           \endlist

           You can also make the listing start at any character or
           number by simply provide the number or character you want
           to start at. For example:

           \code
           / *!
               \list G
                   \o How to Learn Qt
                   \o Installation
                   \o Tutorial and Examples
               \endlist
           * /
           \endcode

           will be rendered as

           \list G
               \o How to Learn Qt
               \o Installation
               \o Tutorial and Examples
           \endlist

           See also \l {o}{\\o}.

    \row
        \o \bold \\o \target o
        \o \bold {The \\o command announce a table or list item.}

           Earlier we used the \l {i}{\\i} command for this purpose. For more
           information see the \l
           {26-qdoc-commands-compatibility.html#o-versus-i}{compatibility}
           section.

           The command can only be used within the \l{table}
           {\\table...\\endtable} or \l{list}{\\list... \\endlist}
           commands.

           It considers everything until the next occurrence
           of the \\o command, or the currently applicable \l
           {table}{\\endtable} or \l {list}{\\endlist} command, as its
           argument. For examples, see \l {table}{\\table} and \l
           {list}{\\list}.

           If the command is used within a table, you can in addition
           specify how many rows or columns the item should span. For
           example:

           \code
           / *!
               \table
               \header
                   \o {3,1} This header cell spans three columns
                      but only one row.
               \row
                   \o {2, 1} This table item spans two columns
                      but only one row
                   \o {1, 2} This table item spans only one column,
                   but two rows.
               \row
                   \o A regular table item
                   \o A regular table item
               \endtable
           * /

               </table>

           The brief text is used to introduce the documentation of
           the associated object, and in lists generated using the \l
           {generatelist}{\\generatelist} command.

           The \\brief command can be used in two significant

           namespaces and header files}, and \l {brief property}{one
           for properties and variables}.

           \target brief property

           When the \\brief command is used to describe a property or
           a variable, the brief text must only be a sentence fragment
           and start with "whether" (for boolean properties and
           variables) or "the" (for any other property or variable).

           For example the boolean QWidget::isWindow property:

           \code
           / *!
               \property QWidget::isActiveWindow
               \brief whether this widget's window is the active window

               The active window is the window that contains the widget that
               has keyboard focus.

               When popup windows are visible, this property is true
               for both the active window \e and for the popup.

               \sa activateWindow(), QApplication::activeWindow()
           * /

           and the QWidget::geometry property

           \code
           / *!
               \property QWidget::geometry
               \brief the geometry of the widget relative to its parent and
               excluding the window frame

               When changing the geometry, the widget, if visible,
               receives a move event (moveEvent()) and/or a resize
               event (resizeEvent()) immediately.

               ...

              \sa frameGeometry(), rect(), ...

               This property holds the geometry of the widget relative

           \target brief class

           When the \\brief command is used to describe a class, the
           brief text should be a complete sentence and must start
           like this:

           \code

           \endcode

           and likewise when the command is used for namespaces or
           header files.

           \warning The brief statement is used as the first
           paragraph of the detailed description. Do not repeat the
           sentence.

               Constructs a preview window widget with \i parent.

               \target function
               \raw HTML
                   <h3>setWindowFlags(Qt::WindowFlags flags)</h3>
               \endraw

               Sets the widgets flags using the
               QWidget::setWindowFlags() function.

               Then runs through the available window flags,
               creating a text that contains the names of the flags
               that matches the flags parameter, displaying
               the text in the widgets text editor.

           Using \\brief with a namespace can for example look like this:

           \code
           / *!
               \namespace Qt

               \brief The Qt namespace contains miscellaneous identifiers
               used throughout the Qt library.
           * /
           \endcode

           and finally using \\brief with a header file can look
           something like this:

           \code
           / *!
               \headerfile <QtGlobal>
               \title Global Qt Declarations

               \brief The <QtGlobal> header file provides basic
               declarations and is included by all other Qt headers.

               \sa <QtAlgorithms>
           * /
           \endcode

           See also \l{property}{\\property}, \l{class}{\\class},
           \l{namespace}{\\namespace} and  \l{headerfile}{\\headerfile}.

        \o \bold {The \\legalese command, and the corresponding \\endlegalese
           command, delimit a licence agreement.}

           If the \\endlegalese command is omitted, QDoc will still
           process the \\legalese command but considers the rest of
           the documentation page as the license agreement.

           Ideally, the license documentation is located where the
           licensed code is used.

           Later the documentation identified by the \\legalese
           command can be accumulated into a list using the \l
           {generatelist}{\\generatelist} command with the \c legalese
           argument. This is useful to generate an overview of all the
           licenses associated with the source code.

               On X11, Qt also supports drops via the Motif Drag \&

        \o \bold {The \\expire command allows you to define an expiration
           date for your documentation.}

           When using the \\expire command, QDoc will emit a warning
           when the current date is larger than the specified
           date. The command accepts one argument; the argument's
           format is yyyy-mm-dd. For example:

           \code
           / *!
               \page porting.html

               \title Porting to Qt 3.x

               \expire 2004-12-31

               This document describes porting applications from Qt
               2.x to Qt 3.x.

               The Qt 3.x series is not binary compatible with the
               2.x series.
               ...
           * /

        \o \bold \\generatelist \target generatelist
        \o \bold {The \\generatelist command expands to a list of
           various documentation or links to documentation.}

           For example in the Qt Reference Documentation:

           \code
           / *!
               \page classes.html
               \title All Qt Classes (main index)

               For a shorter list that only includes the most
               frequently used classes, see \l{Qt's Main Classes}. For
               a list of Qt 3 support classes, see \l{Qt3Support
               Classes}.

               \generatelist classes
           * /
           \endcode

           is used to generate \l {All Qt Classes (main index)}.

           The command accepts the following arguments:

           \target table example

           \list
           \o \c annotatedclasses

              The \c annotatedclasses argument provides a table
              containing the names of all the classes, and a
              description of each class. Each class name is a link to
              the class's reference documentation.

              A class is identified within the documentation by the
              the \l {class}{\\class} command, and the descriptions
              are based on the argument of the \l {brief}{\\brief}
              commands in the class documentation.

           \target list example

           \o \c classes

              The \c classes argument provides a complete alphabetical
              list of the classes. Each class name is a link to the
              class's reference documentation.

              A class is identified within the documentation by the
              the \l {class}{\\class} command.

           \o \c classesbymodule

              This particular argument requests an additional argument,
              i.e. a specification of the module.

              For example:

              \code
              / *!
                  \page qtgui.html
                  \contentspage Qt Classes by Module
                  \previouspage QtCore Classes
                  \nextpage QtNetwork Classes

                  \title QtGui Classes

                  \keyword QtGui

                  \generatelist {classesbymodule QtGui}
              * /
              \endcode

              Together, these arguments provide a table containing the
              classes considered members of the specified module,
              accompanied with a brief description. Each class name is
              a link to the class's reference documentation.

              The generated table is rendered similarily to the one
              generated when using the \l {table example}{\c
              annotatedclasses} argument.

              For the basic classes in Qt, a class's module is
              determined by its location, i.e. its directory. However,
              for extensions, like ActiveQt and Qt Designer, a class
              is related to a module with the \l
              {inmodule}{\\inmodule} command.

           \o \c classesbyedition

              This particular argument requests an additional argument,
              i.e. a specification of the edition.

              For example:

              \code
              / *!
                  \page console-edition-classes.html
                  \title Qt Console Edition Classes

                  \generatelist{classesbyedition Console}
              * /
              \endcode

              Together, these arguments provide a table containing the
              classes considered members of the specified edition,
              accompanied with a brief description. Each class name is
              a link to the class's reference documentation.

              The edition a given class can be found in is determined by
              the module it belongs to.

           \o \c compatclasses

              The \c compatclasses argument provides a complete and
              alphabetical list of the support classes.  A support
              class is identified within the documentation by the \l
              {compat}{\\compat} command. Each class name is a link to
              the class's reference documentation. The list is
              rendered similarily to the list generated by the \l
              {list example}{\c classes} argument.

              \warning The \c classesbymodule argument will at some
              point replace the this argument.

           \o \c functionindex

              The \c functionindex argument provides a complete
              alphabetical list of all the documented member
              functions.

              For example:

           \o \c mainclasses

              The \c mainclasses argument provides a complete
              alphabetical list of the main classes. Each class name
              is a link to the class's reference documentation. A
              class is related to the group of main classes by using
              the \l {mainclass}{\\mainclass} command.

              The list is rendered similarily to the list generated by
              the \l {list example}{\c classes} argument.

           \o \c overviews

              The \c overviews argument provides a complete
              alphabetical overview of the documentation. Each list
              entry is a link to the respective documentation page.

              The list includes pages declared using commands like \l
              {page}{\\page} and \l {group}{\\group}. The list omits
              examples and classes, and only lists the first page of
              documentation that contains two or more pages using
              commands like \l {nextpage}{\\nextpage}.

           \o \c related

              The \c related argument is used in combination with the
              \l {group}{\\group} command to list all the overviews
              related to the given group. Each list entry is a link to
              the respective documentation page.

           \o \c relatedinline

              The \c related argument is used in combination with the

              related to the given group. The various documentation
              snippets are copied directly into the group page.

           \o \c service

              The \c service argument provides a complete alphabetical
              list of the services. Each service name is a link to the
              service's reference documentation.

              A service is identified within the documentation by the
              \l {service}{\\service} command.

           the condition specified by the command's argument is true.}

           The command reads the rest of the line and parses it as an

           You can also define the preprocessor symbol manually on the

               The Qt 3 support library is provided to keep old
               source code working.

               In addition to the \c Qt3Support classes, Qt 4 provides
               compatibility functions when it's possible for an old
               API to cohabit with the new one.

               \if !defined(QT3_SUPPORT)
                   \if defined(QT3_SUPPORTWARNINGS)
                       The compiler emits a warning when a
                       compatibility function is called. (This works
                       only with GCC 3.2+ and MSVC 7.)
                   \else
                       To use the Qt 3 support library, you need to
                       have the line QT += qt3support in your .pro
                       file (qmake automatically define the
                       QT3_SUPPORT symbol, turning on compatibility
                       function support).

                       You can also define the symbol manually (e.g.,
                       if you don't want to link against the \c
                       Qt3Support library), or you can define \c
                       QT3_SUPPORT_WARNINGS instead, telling the
                       compiler to emit a warning when a compatibility
                       function is called. (This works only with GCC
                       3.2+ and MSVC 7.)

               \endif

            The command takes a file name as an argument, and is
            useful when some piece of the documentation is used
            repeatedly: Move the repetetive text into a separate file,
            and use the \\include command whenever you want to insert
            the separate documentation.

            The contents of such a file should follow QDoc syntax,
            excluding the enclosing \c{/}\c{*!} ... \c{*}\c{/} marks.
            To ensure that QDoc won't attempt to read the file as a
            stand-alone piece of documentation, we recommend that you
            use the \c .qdocinc extension.

            For example:

            \code
            / *!
                \page corefeatures.html
                \title Core Features

                   This article shows how to maintain sets of
                   "attributes" (QVariant values), and how to allow
                   users to view and edit them using dialogs that are
                   created dynamically based on the attributes and
                   their types.
               \endabstract

               The Attributes class described in this article holds a
               set of QVariants, and can create a dialog to present
               the QVariants to the user in an appropriate way.

    \title Topical Commands

    The topical commands tell QDoc what is being documented
    (i.e. existing units like classes, functions and examples), and
    some of the commands allows you to create extra pages.

    \section1 Alphabetical List

    \section1 General Description

    When QDoc is processing a comment, it will try to connect the
    documentation to the source code. For that reason it will first
    look for the topical commands. If there is no such command, it
    will try to tie the documentation to the immediately following
    code. If there is no topical command, and the documentation cannot
    be tied to following code, the documentation is simply lost.

    \target topical argument

    The documented unit's name is passed as the unique argument for
    all the topical commands. The argument's naming convention is the
    documented unit's complete name. For example:

    \code
        \enum QComboBox::InsertPolicy
    \endcode

    Functions is a special case, the argument's naming convention for
    the \l {fn}{\\fn} command is that of the function's definition
    outside the class definition. For example:

    \code
        \fn void PreviewWindow::setWindowFlags()
    \endcode

    A topical command can appear anywhere in a comment, but must stand
    alone on its own line. If the argument spans several lines, make
    sure that each line (except the last one) is ended with a
    backslash. In addition QDoc counts parentheses, which means that
    if it encounters a '(' it considers everything until the closing
    ')' as its argument.

    If a topical command is repeated with different arguments, the
    same documentation will appear for both the units. For example:

    \code
    / *!
        \fn void PreviewWindow::setWindowFlags()
        \fn void ControllerWindow::setWindowFlags()

        Sets the widgets flags using the QWidget::setWindowFlags()
        function.

        Then runs through the available window flags, creating a text
        that contains the names of the flags that matches the flags
        parameter, displaying the text in the widgets text editor.
    * /
    \endcode

    The \c PreviewWindow::setWindowFlags() and \c
    ControllerWindow::setWindowFlags() functions will get the same
    documentation.

        \o \bold {The \\class command tells QDoc that a class is
           part of the public API, and lets you enter a detailed
           description.}

           The command follows \l {topical argument}{the general
           topical command convention} for the argument, and supports
           nested classes, for example:

           \code
           / *!
               \class QMap::iterator

               \brief The QMap::iterator class provides an STL-style
               non-const iterator for QMap and QMultiMap.

               QMap features both \l{STL-style iterators} and
               \l{Java-style iterators}. The STL-style iterators ...
           * /
           \endcode

           The generated HTML documentation for the specified class is
           put in \c <lower-case>classname.html. For example, the
           documentation for the \c PreviewWindow class is located in
           \c previewwindow.html.

           \target framework

           In addition to render the detailed description, the \\class
           comand will generate the documentation framework, i.e. a
           list of the class's types, properties, functions, signals
           and slots with empty documentation.

           The command is typically accompanied with a \l
           {brief}{\\brief} command, a \l {mainclass}{\\mainclass}
           command, an \l {ingroup}{\\ingroup} command and a \l
           {sa}{\\sa} command. For example:

           \code
           / *!
               \class PreviewWindow
               \brief The PreviewWindow class is a custom widget

           The enum items are documented using the \l {value}{\\value}
           command. If an item isn't documented, QDoc will emit a
           warning. This can be avoided using the \l
           {omitvalue}{\\omitvalue} command excluding an item from the
           documentation. The enum documentation will be located in
           the associated class, header file or namespace
           documentation.

           For example:

           \code
               enum Corner {
                   TopLeftCorner = 0x00000,

               This enum type specifies a corner in a rectangle:

        \o \bold \\fn \target fn
        \o \bold {The \\fn command allows you to document a function.}

           The command follows \l {topical argument}{the general
           topical command convention} for the argument. In particular
           it is important that the return type of the function,
           whether it is \c const or not and the complete set of
           arguments with type are included in the argument.  If the
           referenced function doesn't exist, QDoc will emit a
           warning.

           Also, the \\fn command is QDoc's default command, i.e. when
           no topical command can be found within a QDoc comment, QDoc
           tries to tie the documentation to the following code as if
           it was function documentation.

           This means that the command normally isn't necessary since
           the recommended style is to write the function
           documentation directly before the function implementation
           in the \c .cpp file. In fact, it should only be used for
           inline functions implemented in the \c .h file.

           For example:

           \code
           / *!
               \fn bool QToolBar::isAreaAllowed(Qt::ToolBarArea area) const

               Returns true if this toolbar is dockable in the given
               \a area; otherwise returns false.

           The command follows \l {topical argument}{the general

           command is typically followed by a \l {title}{\\title}
           command and a short introduction to the group.  The
           generated HTML documentation for the specified group is put
           in <lower-case>\i{group}.html.

           A class can be related to a group by using the \l
           {ingroup}{\\ingroup} command. In addition, overviews can be
           related to a group using the same command, but these must
           be listed explicitly using the \l
           {generatelist}{\\generatelist} command (see example below).

           Each class is listed with a link to the class reference
           page and a brief description based on the classes' \l

           QDoc recognizes three different macro syntax: function-like

           Q_PROPERTY() and macros without parentheses like Q_OBJECT.

           The \\macro command must be followed by a \l

               \title About Qt

               Qt by Trolltech is a C++ toolkit for cross-platform GUI
               application development. Qt provides single-source
               portability across Microsoft Windows, Mac OS X, Linux,
               and all major commercial Unix variants. (A version of
               Qt 4 for embedded Linux will be available in
               August/September 2005.)

               Qt provides application developers with all the
               functionality needed to build applications with
               state-of-the-art graphical user interfaces. Qt is fully
               object-oriented, easily extensible, and allows true
               component programming.

               ...

        \o \bold {\\externalpage} \target externalpage
        \o \bold {The \\externalpage command gives a title to
            an external URL.}

           The command follows \l {topical argument}{the general
           topical command convention} for the argument.

           For example:

           \code
           / *!
               \externalpage http://www.trolltech.com/products/embedded/index.html
               \title Qtopia Core
           * /
           \endcode

           The QDoc comment above allows you to link to the Qtopia
           Core webpage by simply linking to the given title. For
           example:

           \code
           / *!
               The broad scope of the \l {Qtopia Core} API enables it to
               be used across a wide variety of development projects.
           * /
           \endcode

           will be rendered as

           \quotation
               The broad scope of the \l
               {http://www.trolltech.com/products/embedded/index.html}{Qtopia
               Core} API enables it to be used across a wide variety
               of development projects.
           \endquotation

           To achieve the same result without using the
           \\externalpage command, you would have to hard code the
           adress into your documentation:

           \code
           / *!
               The broad scope of the \l
               {http://www.trolltech.com/products/embedded/index.html}{Qtopia
               Core} API enables it to be used across a wide variety
               of development projects.
           * /
           \endcode

           The \\externalpage command makes it easier to maintain the
           documentation. If the adress changes, you only need to change the
           argument of the \\externalpage command.

    \row
        \o \bold \\property \target property
        \o \bold {The \\property command allows you to document a Qt
           property.}

           The command follows \l {topical argument}{the general
           topical command convention} for the argument.

           A property is defined using the Q_PROPERTY() macro. The
           macro takes as arguments the property's name and its set,
           reset and get functions. For example:

           \code
           Q_PROPERTY(QString state READ state WRITE setState)
           \endcode

           The set, reset and get functions don't need to be
           documented, documenting the property is sufficient. QDoc
           will generate a list of the access function that will
           appear in the property documentation which in turn will be
           located in the documentation of the class that defines the
           property.

           The \\property command is typically accompanied with a \l
           {brief}{\\brief} command.  In the case of a property, the
           \l {brief}{\\brief} command's argument is a sentence
           fragment that will be included in a one-sentence
           description of the property generated by QDoc. The command
           follows the same rules for the \l {brief
           property}{description} as the \l {variable}{\\variable}
           command.

           For example:

           \code
           / *!
               \property QPushButton::flat
               \brief whether the border is disabled

               This property's default is false.
           * /
           \endcode

               This property holds whether the border is disabled.

               This property's default is false.

               \o \bold { bool isFlat () const}

            The command takes two arguments, the service class's name
            and the associated alias. For example:

    \title Contextual Commands

    The contextual commands provide QDoc with information, that it
    wouldn't figure out otherwise, about the documented object. For
    example whether a class is thread-safe or not.

    These commands can appear anywhere within a QDoc comment.

    The navigation commands allow you to link the pages of a multipage
    document together. They provide the components of a navigation bar
    at the top and bottom of the document. They also provide browser
    and search engine support.

    In addition, the \l {indexpage}{\\indexpage} and \l
    {startpage}{\\startpage} commands specifies links to the page's
    index page and start page. These links are used by browsers and
    search engines.

    The index page is typically an alphabetical list of the document's
    titles and topics, while the start page is the page considered by
    the author to be the starting point of a multipage document.

    The links are included in the generated HTML source code but has
    no visual effect on the documentation:

    \code
    <head>
        ...
        <link rel="index" href="index.html" />
        <link rel="start" href="basicqt.html" />

        \o \bold {The \\previouspage command links the current page
           to the previous one in an ordered series of documents}.

           The command has two arguments, each enclosed by curly
           braces: The first is the link target, i.e. the title of the
           previous page, the second is the link text. If the page's
           title is equivalent to the link text, the second argument
           can be omitted.

           The command must stand alone on its own line.

           In the end, the link is rendered at the top and bottom of
           the current page. For an example, see the \l {General
           Description} section.

    \row
        \o \bold \\nextpage \target nextpage
        \o \bold {The \\nextpage command links the current
           page to the next page in an ordered series of documents}.

           The command follows the same syntax and argument convention
           as the \l {previouspage}{\\previouspage} command.

           For an example, see the \l {General Description} section.

    \row
        \o \bold \\startpage \target startpage
        \o \bold {The \\startpage command specifies the first document
           in a collection of documents.}

           The command must stand alone on its own line, and its
           unique argument is the title of the first document.

           QDoc will generate a link to the specified document which
           is included in the HTML file but has no visual effect on
           the documentation. The generated link type tells browsers
           and search engines which document is considered by the
           author to be the starting point of the collection.

           For an example, see the \l {General Description} section.

    \row
        \o \bold \\contentspage \target contentspage
        \o \bold {The \\contentspage command links the current
           page to a contents page}.

           The command follows the same syntax and argument convention
           as the \l {previouspage}{\\previouspage} command.

           For an example, see the \l {General Description} section.

    \row

        \o \bold {The \\indexpage command specifies a document providing
           an index for the current document}.

           The command must stand alone on its own line, and its

           QDoc will generate a link to the specified document which
           is included in the HTML file but has no visual effect on
           the documentation. The generated link type tells browsers
           and search engines which document is considered by the

    \title Status Commands

    The usage commands can indicate whether a documented object is
    under development, becoming obsolete, provided for compatibility
    reasons or simply not part of the public interface. They can
    describe the history of minor versions. And they can also describe
    a documented object's ability to handle multithreaded programming.

           The \\preliminary command expands to a notification in the
           function documentation, and marks the function as
           preliminary when it appears in lists. For example:

           \code

           The command must stand on its own line.

           When generating the reference documentation for a class,
           QDoc will create and link to a separate page documenting
           its obsolete functions.  Usually an equivalent function is
           provided as an alternative.

           For example:

           \code
           / *!
               \fn MyClass::MyObsoleteFunction
               \obsolete

           The command must stand on its own line.

           Usually an equivalent function or class is provided as an
           alternative.

           If the command is used within the documentation of a class,
           the command expands to a warning that the referenced class
           is part of the support library. The warning is located on
           top of the associated documentation. For example:

           \code
           / *!
               \class MyQt3SupportClass
               \compat

           on the top of the MyQt3SupportClass class reference.

           If the command is used when documenting a function, QDoc
           will create and link to a separate page documenting Qt 3
           support members when generating the reference documentation
           for the associated class. For example:

           QDoc ignores the documentation as well as the documented

    \title Thread Support Commands

    The thread support commands specify the level of support for
    multithreaded programming of a class or function.

    \section1 Alphabetical List

    \l {17-qdoc-commands-thread.html#nonreentrant}{\\nonreentrant},
    \l {17-qdoc-commands-thread.html#reentrant}{\\reentrant},
    \l {17-qdoc-commands-thread.html#threadsafe}{\\threadsafe}

    \section1 General Description

    There are three levels of support for multithreaded programming of
    a class or function: \c threadsafe, \c reentrant and \c
    nonreentrant.

    The default is \c nonreentrant which means that the associated
    class or function cannot be called by multiple threads. \c
    Reentrant and \c threadsafe are levels primarily used for classes.

    \c Reentrant means that all the functions in the referenced class
    can be called simultaneously by multiple threads, provided that
    each invocation of the functions reference unique data. While \c
    threadsafe means that all the functions in the referenced class
    can be called simultaneously by multiple threads even when each
    invocation references shared data.

    When a class is declared \c reentrant or \c threadsafe, using the
    \l {reentrant}{\\reentrant} and \l {threadsafe}{\\threadsafe}
    commands respectively, functions in the referenced class can be
    declared \c nonreentrant, using the \l
    {nonreentrant}{\\nonreentrant} command, excluding the functions
    from the general view.

    For example:

    \code
    / *!
        \class QLocale
        \brief The QLocale class converts between numbers and their
        string representations in various languages.

        \reentrant
        \ingroup i18n
        \ingroup text
        \mainclass

        QLocale is initialized with a language/country pair in its
        constructor and offers number-to-string and string-to-number
        conversion functions similar to those in QString.

        ...
    * /

    / *!
        \nonreentrant

        Sets the global default locale to \a locale. These values are
        used when a QLocale object is constructed with no
        arguments. If this function is not called, the system's locale
        is used.

        \warning In a multithreaded application, the default locale
        should be set at application startup, before any non-GUI
        threads are created.

        \sa system() c()
    * /
    void QLocale::setDefault(const QLocale &locale)
    {
        default_d = locale.d;
    }
    \endcode

    will be rendered as

        \bold {Note:} All the functions in this class are \l

        {QLocale::setDefault()}{setDefault()}.

            <h3>void QLocale::setDefault ( const QLocale & locale ) </h3>
        \endraw

        Sets the global default locale to locale. These values are
        used when a QLocale object is constructed with no
        arguments. If this function is not called, the system's locale
        is used.

        \warning In a multithreaded application, the default locale
        should be set at application startup, before any non-GUI
        threads are created.

        \warning This function is not reentrant.

        See also \l {QLocale::system()}{system()} and \l
        {QLocale::c()}{c()}.

        ...
    \endquotation

    As shown above, QDoc generates a notification when a class is
    declared reentrant, and lists the exceptions (the declared
    nonreentrant functions). A link to the general documentation on \l
    {threads.html#reentrant}{reentrancy and thread-safety} is
    included.  In addition a warning, "\bold Warning: This function is
    not reentrant.", is generated in the nonreentrant functions'
    documentation.

    QDoc will generate the same notification and warnings when a class
    is declared threadsafe.

    For more information see the general documentation on \l
    {threads.html#reentrant}{reentrancy and thread-safety}.

        \o \bold {The \\overload command indicates that the 
           function is a secondary overload of its name.}

           The command must stand on its own line.

           For any overloaded function (except constructors), QDoc
           expects one primary version of the function and all the 
	   the overloads marked with the \bold{\\overload command}.
           The primary version should be fully documented. Each 
	   overload can have whatever extra documentation you want
	   to add for just that overload. 

	   From Qt 4.5, you can include the function name plus '()'
	   as a parameter to the \bold{\\overload} command, which 
	   will include a standard \i{This function overloads...} 
	   line of text with a link to the documentation for the 
	   primary version of the function. 

	   For example:

           \code
           / *!
               \overload addAction()

               This convenience function creates a new action with an
               \a icon and some \a text. The function adds the newly
               created action to the menu's list of actions, and
               returns it.

               \sa QWidget::addAction()
           * /
           QAction *QMenu::addAction(const QIcon &icon, const QString &text)

               {QWidget::addAction}().
           \endquotation

	   If you don't include the function name with the
	   \bold{\\overlaod} command, then instead of the "This
	   function overloads..." line with the link to the
	   documentation for the primary version, you get the old
	   standard line:

           where the reimplementation has no effect on the interface.}

           The command must stand on its own line.

           QDoc will omit the reimplemented function from the class
           reference. For example:

        \o \bold \\mainclass \target mainclass
        \o \bold {The \\mainclass command relates the documented class to
           a group called mainclasses.}

           The command must stand on its own line.

           For example:

           \code
           / *!
               \class QWidget qwidget.h
               \brief The QWidget class is the base class of
               all user interface objects.

               \mainclass

               ...
           * /
           \endcode

           will ensure that the QWidget class is included in the \c
           mainclasses group, which means, for example, that the class
           will appear on the list created by calling the \l
           {generatelist}{\\generatelist} command with the \c
           mainclasses argument:

           \l http://qt.nokia.com/doc/4.0/mainclasses.html

           See also \l {generatelist}{\\generatelist}.

    \row
        \o \bold \\ingroup \target ingroup

        \o \bold {The \\ingroup command indicates that the given
           overview or documented class belongs to a certain group of
           related docmentation.}

           A class or overview may belong to many groups.

           The \\ingroup command's argument is a group name, but note
           that the command considers the rest of the line as part of
           its argument. Make sure that the group name is followed by
           a linebreak. For example:

           \code
           / *!
               \class QDir
               \brief The QDir class provides access to directory
                      structures and their contents.

               \ingroup io
               ...
           * /
           \endcode

           will ensure that the QDir class is included in the \c io
           group, which means, for example, that QDir will appear on
           the list created by calling the \l {group}{\\group} command
           with the \c io argument.

           Note that to list overviews that are related to a given
           group, you must generate the list exlicitly by using the \l
           {generatelist}{\\generatelist} command with the \c related
           argument.

           See also \l {group}{\\group}.
    \row
        \o \bold \\inmodule \target inmodule
        \o \bold {The \\inmodule command relates the documented class
           to the module specified by the command's argument.}

           For the basic classes in Qt, a class's module is determined
           by its location, i.e. its directory. However, for
           extensions, like ActiveQt and Qt Designer, a class needs to
           be related to a module explicitly.

           The command's argument is a module name, but note that the
           command considers the rest of the line as part of its
           argument. Make sure that the module name is followed by a
           linebreak. For example:

           \code
           /*!
               \class QDesignerTaskMenuExtension
               \inmodule QtDesigner
           * /
           \endcode

           will ensure that the QDesignerTaskMenuExtension class is
           included in the \c QtDesigner module, which means, for
           example, that the class will appear on the list created by
           calling the \l {generatelist}{\\generatelist} command with
           the \c {{classesbymodule QtDesigner}} argument.

    When running QDoc to generate the documentation, you must specify
    a configuration file on the command line:

    \quotation
        \bold {/currentdirectory$ qdoc3 my-documentation.qdocconf}
    \endquotation

    \section1 General Description

    The configuration file is a list of entries of entries of the form
    \i {"variable = value"}. Using the configuration variables, you
    can define where QDoc should find the various source files, images
    and examples, where to put generated documentation etc. The
    configuration file can also contain directives like \c
    include. For an example, see the \l minimum.qdocconf file.

    In addition, you can use some particular configuration variables
    to make QDoc support derived projects, i.e make the projects, for
    example Qt Solutions, contain links to the online Qt
    documentation. These variables are documented in the \l
    {Supporting Derived projects} section. In this section you can
    also find out how to use these variables to support your derived
    projects.

    If some of the variable keys have the same values, they can be set
    at the same time. For example:

    \code
    {header, source}dirs = kernel
    \endcode

    is equivalent to

    \code
    headerdirs = kernel
    sourcedirs = kernel
    \endcode

    A variable's value can be set using either '=' or '+='. The
    difference is that '=' overrides any previously set value, while
    '+=' only adds the value to the previously set ones.

    In general, some of the variables accepts a list of strings as
    their value, while others only accept a single string. If you
    provide a variable of the latter type with several strings they
    will simply be concatenated. The quotes around the value string
    are optional. But applying them allows you to use special
    characters like '=' and ' \" ' within the string. For example:

    \code
    HTML.postheader = "<a href=\"index.html\">Home</a>"
    \endcode

    If an entry spans many lines, use a backslash at the end of every
    line but the last:

    \code
    sourcedirs = kernel \
                 tools \
                 widgets
    \endcode

    \title General Configuration Variables

    With the general QDoc configuration variables, you can define
    where QDoc will find the various source files it needs to generate
    the documentation, as well as the directory to put the generated
    documentation. You can also do some minor manipulation of QDoc
    itself, controlling its output and processing behavior.

    \section1 Variable Descriptions

    \table

    \header
        \o Variable
        \o Description

    \row
        \o \bold alias \target alias
        \o \bold {The \c alias variable renames a QDoc command.}

           The general syntax is \tt {alias.\i{original-command-name}
           = \i temporary-command-name}.

           For example:

           \code
           alias.i = e
           \endcode

           renames the built-in command \\i (italics) to \\e.

           The \c alias variable is often used for compatibility
           reasons; for more information see the \l {QDoc
           Compatibility}{compatibility section}.

           See also \l macro.

    \row
        \o \bold codeindent \target codeindent
        \o \bold {The \c codeindent variable specifies the level of
           indentation that QDoc uses when writing code snippets.}

           QDoc originally used a hard-coded value of four spaces for
           code indentation to ensure that code snippets could be easily
           distinguished from surrounding text. Since we can use
           \l{HTML Specific Configuration Variables#HTML.stylesheets}{stylesheets} to
           adjust the appearance of certain types of HTML elements, this
           level of indentation is not always required.

    \row
        \o \bold defines \target definesvariable
        \o \bold {The \c defines variable specifies the C++ preprocessor
           symbols that QDoc will recognize and respond to.}

           When a preprocessor symbol is specified using the \c
           defines variable, you can also use the \l {if}{\\if}
           command to enclose documentation that only will be included
           if the preprocessor symbol is defined.

           The values of the variable are regular expressions (see
           QRegExp for details). By default, no symbol is defined,
           meaning that code protected with #ifdef...#endif will be
           ignored.

           For example:

           \code
           defines = Q_QDOC \
                     QT_.*_SUPPORT \
                     QT_.*_LIB \
                     QT_COMPAT \
                     QT3_SUPPORT \
                     Q_WS_.* \
                     Q_OS_.* \
                     Q_BYTE_ORDER \
                     __cplusplus
           \endcode

           ensures that QDoc will process the code that requires these
           symbols to be defined. For example:

           \code
           #ifdef Q_WS_WIN
               HDC getDC() const;
               void releaseDC(HDC) const;
           #endif
           \endcode

           Since the Q_WS_.* regular expression (specified using the
           \c defines variable) matches Q_WS_WIN, QDoc will process
           the code within #ifdef and #endif in our example.

           You can also define preprocessor symbols manually on the
           command line using the -D option. For example:

           \code
               currentdirectory$ qdoc3 -Dconsoleedition qt.qdocconf
           \endcode

           In this case the -D option ensures that the \c
           consoleedition preprocessor symbol is defined when QDoc
           processes the source files defined in the qt.qdocconf file.

           See also \l falsehoods and \l {if}{\\if}.

    \row
        \o \bold edition \target edition
        \o \bold {The \c edition variable specifies which modules are
           included in each edition of a package, and provides QDoc
           with information to provide class lists for each edition.}

           This feature is mostly used when providing documentation
           for Qt packages.

           The \c edition variable is always used with a particular
           edition name to define the modules for that edition:

           \code
           edition.Console      = QtCore QtNetwork QtSql QtXml
           edition.Desktop      = QtCore QtGui QtNetwork QtOpenGL QtSql QtXml \
                                  QtDesigner QtAssistant Qt3Support QAxContainer \
                                  QAxServer
           edition.DesktopLight = QtCore QtGui Qt3SupportLight
           \endcode

           In the above examples, the \c Console edition only includes
           the contents of four modules. Only the classes from these
           modules will be used when the
           \l{Miscellaneous Commands#generatelist}{generatelist} command
           is used to generate a list of classes for this edition:

           \code
           \generatelist{classesbyedition Console}
           \endcode

    \row
        \o \bold exampledirs \target exampledirs
        \o \bold {The \c exampledirs variable specifies the directories
           containing the source code of the example files.}

           The \l {examples}{\c examples} and \c exampledirs variables
           are used by the \l {quotefromfile}{\\quotefromfile}, \l
           {quotefile}{\\quotefile} and \l {example}{\\example}
           commands.  If both the \l {examples}{\c examples} and \c
           exampledirs variables are defined, QDoc will search in
           both, first in \l {examples}{\c examples} then in \c
           exampledirs.

           QDoc will search through the directories in the specified
           order, and accept the first matching file it finds. It will
           only search in the specified directories, \i not in
           subdirectories.

           For example:

           \code
           exampledirs = $QTDIR/doc/src \
                         $QTDIR/examples \
                         $QTDIR \
                         $QTDIR/qmake/examples

           examples    = $QTDIR/examples/widgets/analogclock/analogclock.cpp
           \endcode

           When processing

           \code
           \quotefromfile widgets/calculator/calculator.cpp
           \endcode

           QDoc will then see if there exists a file called \c
           calculator.cpp listed as a value in the \l {examples}{\c
           examples} variable. If it doesn't, it will search in the \c
           exampledirs variable, and first see if there exists a file
           called

           \code
           $QTDIR/doc/src/widgets/calculator/calculator.cpp
           \endcode

           If it doesn't, QDoc will continue looking for a file
           called

           \code
           $QTDIR/examples/widgets/calculator/calculator.cpp
           \endcode

           and so forth.

           See also \l examples.

    \row
        \o \bold examples \target examples
        \o \bold {The \c examples variable allows you to specify individual
           example files in addition to those located in the directories
           specified by the \l {exampledirs}{\c exampledirs} variable.}

           The \c examples and \l {exampledirs}{\c exampledirs}
           variables are used by the \l
           {quotefromfile}{\\quotefromfile}, \l
           {quotefile}{\\quotefile} and \l {example}{\\example}
           commands. If both the \c examples and \l {exampledirs}{\c
           exampledirs} variables are defined, QDoc will search in
           both, first in \c examples then in \l {exampledirs}{\c
           exampledirs}.

           QDoc will search through the values listed for the \c
           examples variable, in the specified order, and accept
           the first one it finds.

           For an extensive example, see the \l {exampledirs}{\c
           exampledirs} command. But note that if you know the file is
           listed in the \c examples variable, you don't need to
           specify its path:

           \code
               \quotefromfile calculator.cpp
           \endcode

           See also \l exampledirs.

    \row
        \o \bold examples.fileextensions \target examples.fileextensions
        \o \bold {The \c examples.fileextensions variable specifies the
           file extensions that qdoc will look for when collecting example
           files for display in the documentation.}

           The default extensions are *.cpp, *.h, *.js, *.xq, *.svg, *.xml
           and *.ui. However, if 

           The extensions are given as standard wildcard expressions.
           You can add a file extension to the filter using '+='. For
           example:

           \code
           examples.fileextensions += *.qrc
           \endcode

           See also \l{headers.fileextensions}.

    \row
        \o \bold extraimages \target extraimages
        \o \bold {The \c extraimages variable tells QDoc to incorporate
           specific images in the generated documentation.}

           QDoc will not recognize images used within HTML (or any
           other markup language). If we want the images to be copied
           from the directories specified by \l {imagedirs}{\c
           imagedirs} (the images in question must be located in these
           directories) to the output directory, we must specify the
           images using the \c extraimages variable.

           The general syntax is \tt {extraimages.\i{format} = \i
           image}. The file extension is optional.

           For example, in \l qt.qdocconf we use a couple of images
           within the HTML.postheader variable which value is pure
           HTML. For that reason, these images are specified using the
           \c extraimages variable:

           \code
           extraimages.HTML = qt-logo
           \endcode

           See also \l images and \l imagedirs.

    \row
        \o \bold falsehoods \target falsehoods
        \o \bold {The \c falsehoods variable defines the truth value of
           specified preprocessor symbols as false.}

           If this variable is not set for a preprocessor symbol, QDoc
           assumes its truth value is true. The exception is '0',
           which value always is false.

           QDoc will recognize, and is able to evaluate, the following
           preprocessor syntax:

           \code
           #ifdef NOTYET
               ...
           #endif

           #if defined (NOTYET)
               ...
           #end if
           \endcode

           However, faced with unknown syntax like

           \code
           #if NOTYET
               ...
           #endif
           \endcode

           QDoc will evaluate it as true by default, \i unless the
           preprocessor symbol is specified within the \c falsehoods
           variable entry:

           \code
           falsehoods = NOTYET
           \endcode

           See also \l defines.

        \o \bold{The \c generateindex variable contains a boolean value that
           specifies whether to generate an index file when HTML documentation
           is generated.}

           By default, an index file is always generated with HTML documentation,
           so this variable is typically only used when disabling this feature
           (by setting the value to \c false) or when enabling index generation
           for the WebXML output (by setting the value to \c true).
    \row

        \o \bold {The \c headerdirs variable specifies the directories

                        $QTDIR/tools/designer/src/lib/uilib
           \endcode

           When executed, the first QDoc will do is to read through
           the headers specified in the \l {headers}{\c headers}
           variable, and the ones located in the directories specified
           in the \c headerdir variable (including all
           subdirectories), building an internal structure of the
           classes and their functions.

           Then it will read through the sources specified in the \l
           {sources}{\c sources}, and the ones located in the
           directories specified in the \l {sourcedirs}{\c sourcedirs}
           varible (including all subdirectories), merging the
           documentation with the structure it retrieved from the
           header files.

           If both the \c headers and \c headerdirs variables are
           defined, QDoc will read through both, first \l {headers}{\c
           headers} then \c headerdirs.

           In the specified directories, QDoc will only read the files
           with the fileextensions specified in the \l
           {headers.fileextensions}{\c headers.fileextensions}
           variable. The default extensions are *.ch, *.h, *.h++,
           *.hh, *.hpp and *.hxx". The files specified by \l
           {headers}{\c headers} will be read independent of their
           fileextensions.

           QDoc will search in both, first in \l {images}{\c images}
           then in \c imagedirs.

           QDoc will search through the directories in the specified
           order, and accept the first matching file it finds. It will
           only search in the specified directories, \i not in
           subdirectories.

           For example:

           QDoc will then see if there exists a file called

           You can filter the images in an image directory using the
           \l {images.fileextensions}{\c images.fileextensions}
           variable.  The general idea behind the \l
           {images.fileextensions}{\c images.fileextensions} variable
           is to enable different image format for different output
           format.

           The idea is to enable different image format for different

    \title Creating Help Project Files

    \section1 Overview
    
    Starting with Qt 4.4, Qt Assistant uses a different system for managing
    Qt documentation that requires QDoc to generate inventories of files in a
    format that is similar to the old style DCF format, but with additional
    features.

    Instead of hard-coding information about the documentation sets for Qt,
    QDoc allows configuration variables to be used to specify which pages are
    to be used in each documentation set it generates. These are specified as
    subvariables of the \c qch variable with each set declared using a unique
    identifier as a subvariable.

    For example, the configuration file for the Qt documentation defines a
    \c Qt documentation set by specifying information about the set as
    subvariables with the \c{qhp.Qt} prefix:

    \code
    qhp.Qt.file                = qt.qhp
    qhp.Qt.namespace           = com.trolltech.qt.440
    qhp.Qt.virtualFolder       = qdoc
    qhp.Qt.indexTitle          = Qt Reference Documentation
    qhp.Qt.indexRoot           = 
    qhp.Qt.extraFiles          = classic.css images/qt-logo.png
    qhp.Qt.filterAttributes    = qt 4.4.0 qtrefdoc
    qhp.Qt.customFilters.Qt.name = Qt 4.4.0
    qhp.Qt.customFilters.Qt.filterAttributes = qt 4.4.0
    qhp.Qt.subprojects         = classes overviews examples
    qhp.Qt.subprojects.classes.title = Classes
    qhp.Qt.subprojects.classes.indexTitle = Qt's Classes
    qhp.Qt.subprojects.classes.selectors = class
    qhp.Qt.subprojects.overviews.title = Overviews
    qhp.Qt.subprojects.overviews.indexTitle = All Overviews and HOWTOs
    qhp.Qt.subprojects.overviews.selectors = fake:page,group,module
    qhp.Qt.subprojects.examples.title = Tutorials and Examples
    qhp.Qt.subprojects.examples.indexTitle = Qt Examples
    qhp.Qt.subprojects.examples.selectors = fake:example

        \o \bold {The \c Cpp.ignoredirectives variable makes QDoc ignore
           the specified non-standard constructs, within C++ source code.}

           If not specified by the \tt {\l Cpp.ignoretokens} or \tt
           {\l Cpp.ignoredirectives} variables, non-standard
           constructs (typically macros) can result in erroneous
           documentation.

           In \l qt.qdocconf:

           \code
           Cpp.ignoredirectives = Q_DECLARE_INTERFACE \
                                  Q_DECLARE_OPERATORS_FOR_FLAGS \
                                  Q_DECLARE_PRIVATE \

                                  __attribute__
           \endcode

           makes sure that when processing the code below, for
           example, QDoc will simply ignore the 'Q_ENUMS' and
           'Q_FLAGS' expressions:

           \code
               class Q_CORE_EXPORT Qt {
                   Q_OBJECT
                   Q_ENUMS(Orientation TextFormat BackgroundMode
                           DateFormat ScrollBarPolicy FocusPolicy
                           ContextMenuPolicy CaseSensitivity
                           LayoutDirection ArrowType)
                   Q_ENUMS(ToolButtonStyle)
                   Q_FLAGS(Alignment)
                   Q_FLAGS(Orientations)
                   Q_FLAGS(DockWidgetAreas)

               public:
                   ...
           };
           \endcode

           The Q_OBJECT macro, however, is an exception: QDoc
           recognizes this particular non-standard construct, so there
           is no need specifying it using the \tt {\l
           Cpp.ignoredirectives} variable.

           Regarding the Q_CORE_EXPORT macro; see the documentation of
           the \tt {\l Cpp.ignoretokens} variable.

           See also \l Cpp.ignoretokens.

    \row
        \o \bold  Cpp.ignoretokens \target Cpp.ignoretokens
        \o \bold {The \c Cpp.ignoretokens variable makes QDoc ignore

           makes sure that when processing the code below, for
           example, QDoc will simply ignore the 'Q_CORE_EXPORT'
           expression:

    \title HTML Specific Configuration Variables

    The HTML specific configuration variables define the generated

    documentation's footer or postheader. The format of the variable
    values are raw HTML.

        \o Description

    \row
        \o \bold HTML.footer \target HTML.footer
        \o \bold {The \c HTML.footer variable defines the content
           of the generated HTML documentation's footer.}

           The footer is rendered at the bottom of the generated
           documentation page.

           The variable's value is given as raw HTML code enclosed by
           quotation marks. Note that if the value spans several
           lines, each line needs to be enclosed by quotation marks.

           For example in \l qt.qdocconf:

           \code
               HTML.footer = "<p /><address><hr /><div align=\"center\">\n" \
                             ...
                             "</tr></table></div></address>"
           \endcode

           The complete variable entry in \l qt.qdocconf provides the
           standard footer of the \l
           {http://qt.nokia.com/doc/4.0/index.html}{Qt Reference
           Documentation}.

    \row
        \o \bold HTML.postheader \target HTML.postheader
        \o \bold {The \c HTML.postheader variable defines the content
           of the generated HTML documentation's postheader.}

           The header is rendered at the top of the generated
           documentation page.

           The variable's value is given as raw HTML enclosed by
           quotation marks. Note that if the value spans several
           lines, each line needs to be enclosed by quotation marks.

           For example in \l qt.qdocconf:

           \code
            HTML.postheader = "<table border=\"0\"..." \
                              ...
                              "<img src=\"images/trolltech-logo.png\" \
                              "align=\"right\" width=\"203\" height=\"32\""\
                              "border=\"0\" />" \
                              "</td></tr>" \
                              "</table>"
           \endcode

           The complete variable entry in \l qt.qdocconf provides the
           standard header of the \l
           {http://qt.nokia.com/doc/4.0/index.html}{Qt Reference
           Documentation}.

    \row
        \o \bold HTML.style \target HTML.style
        \o \bold {The HTML.style variable defines the style for
           the generated HTML documentation.}

           The variable's value is given as raw HTML enclosed by
           quotation marks. Note that if the value spans several
           lines, each line needs to be enclosed by quotation marks.

           For example in \l qt.qdocconf:

           \code
           HTML.style = "h3.fn,span.fn" \
                        "{ margin-left: 1cm; text-indent: -1cm; }\n" \
                        "a:link { color: #004faf; text-decoration: none }\n" \
                        "a:visited" \
                        "{ color: #672967; text-decoration: none }\n" \
                        "td.postheader { font-family: sans-serif }\n" \
                        "tr.address { font-family: sans-serif }\n" \
                        "body { background: #ffffff; color: black; }"
           \endcode

           provides the HTML style for the \l
           {http://qt.nokia.com/doc/4.0/index.html}{Qt Reference
           Documentation}.

    \row
        \o \bold HTML.stylesheets \target HTML.stylesheets
        \o \bold {The HTML.stylesheets variable defines a list of stylesheets
           to use for the generated HTML documentation.}

           Using separate stylesheets for the documentation makes it easier to
           customize and experiment with the style used once the contents has
           been generated. Typically, it is only necessary to define a single
           stylesheet for any set of documentation; for example:

           \code
           HTML.stylesheets = classic.css
           \endcode

           QDoc expects to find stylesheets in the directory containing the
           \l qt.qdocconf file, and it will copy those specified to the output
           directory alongside the HTML pages.

    Some particular configuration variables allow you to use QDoc to
    support Qt-based projects; i.e to make projects, such as Qt Solutions,
    contain references to the online Qt documentation. This
    means that QDoc will be able to create links to the class reference
    documentation, without any explicit linking command.

        \o \bold indexes \target indexes
        \o \bold {The \c indexes variable lists the index files
           that will be used to generate references.}

           For example. to make a derived Qt project contain links to
           the Qt Reference documentation, you need to specify the
           associated index file:

           \code
               indexes = $QTDIR/doc/html/qt.index
           \endcode

           See also \l project and \l url.

    \row
        \o \bold project \target project
        \o \bold {The \c project variable provides a name for the project
           associated with the \c .qdocconf file.}

           The project's name is used to form a file name for the
           associated project's \i index file. For example:

           \code
               project = QtMotif
           \endcode

           This will cause an index file called \c qtmotif.index to be
           created.

           See also \l description and \l indexes.
    \row
        \o \bold url \target url
        \o \bold {The \c url variable holds the base URL for the
            reference documentation associated with the current project.}

            The URL is stored in the generated index file for the
            project. When we use the index on its own, QDoc will use
            this as the base URL when constructing links to classes,
            functions, and other things listed in the index.

            For example:

            \code
                 project     = Qt
                 description = Qt Reference Documentation
                 url         = http://qt.nokia.com/doc/4.0

                 ...
            \endcode

            This makes sure that whenever \c qt.index is used to generate
            references to for example Qt classes, the base URL is
            \c http://qt.nokia.com/doc/4.0.

            See also \l indexes.

    \endtable

    \target howto
    \section1 How to Support Derived Projects

    This feature makes use of the comprehensive indexes generated by
    QDoc when it creates the Qt reference documentation.

    For example, \l qt.qdocconf (the configuration file for Qt)
    contains the following variable definitions:

    \code
        project     = Qt
        description = Qt Reference Documentation
        url         = http://qt.nokia.com/doc/4.0

        ...
    \endcode

    The \l project variable name is used to form a file name for the
    index file; in this case the \c qt.index file is created.  The \l
    url is stored in the index file. Later, when we use the index on
    its own, QDoc will use this as the base URL when constructing
    links to classes, functions, and other things listed in the index.

    In a mini-project, you can use an index file by defining an \l
    indexes configuration variable in your \c .qdocconf file.

    For example, you can create a \c qtmotif.qdocconf file to help you
    check the QtMotif documentation (which is part of Qt Solutions):

    \code
        include($QTDIR/tools/qdoc3/test/compat.qdocconf)

        project                 = QtMotif
        description             = QtMotif Class Documentation
        url                     = http://www.trolltech.com/products/solutions/catalog/4/Migration/qtmotifextension

        indexes                 = $QTDIR/doc/html/qt.index

        outputdir               = html

        headerdirs              = src
        sourcedirs              = src \
                                  examples
        sources.fileextensions  = "*.cpp *.qdoc *.doc"

        exampledirs = examples
    \endcode

    The code above requires that you run QDoc from the directory that
    contains this file. You need to include the compat.qdocconf
    file for compatibility reasons; this is further explained in the
    \l {QDoc Compatibility} section.

    \bold {To resolve the actual links to Qt classes, the
    mini-project's \c .qdocconf file needs to assign a value to the \l
    indexes variable; \c $QTDIR/doc/html/qt.index makes sure that you
    always use the updated index file for the Qt documentation.}

    The only disadvantages with this approach are the extra file that
    QDoc has to generate and the time it takes to do so. Reading the
    index back again later isn't instantaneous either, but it's
    quicker than processing all the Qt classes each time you need to
    write a new document.

    \section1 General Description

    \target reason

    QDoc is a tool that constantly evolves to suit our needs, for that
    reason there are some compatibility issues in the transition
    between old and new practices.

    To make the transition as smooth and rapid as possible, the
    general idea is to adopt the new commands and usage in new
    documentation.  While waiting for the occurrences of the old
    practices to be eliminated from the old parts of the
    documentation, you can map the new commands and usage to the old
    ones using a compat.qdocconf file.

    A compat.qdocconf file is a separate \c .qdocconf file which you
    can include in your main configuration file. It typically contains
    the mapping between old and new commands using the \l alias and \l
    {22-qdoc-configuration-generalvariables.html#macro}{macro}
    configuration variables.

    \section1 Qt Compatibility

    In Qt's documentation there still exist occurrences of old
    commands, and the Qt \l {qt.qdocconf}{configuration file} needs to
    include the compat.qdocconf file tailored for Qt. For more
    detailed information about the commands creating compatibility
    issues, see the \l {Command Comments}{command comments}.

    \row
        \o \\i \target i-versus-e
        \o \\e
        \o Earlier we
           used the \\i command to indicate a list or table item, and
           the \\e command for rendering in italic. Now we want the
           \\i command to render in italic discarding the
           \\e command name.

           \bold {We still need to use the \\e command to render in
           italic in new documentation for \l {reason}{compatibility
           reasons}}.

    \row
        \o \\include \target include-versus-input
        \o \\input
        \o The \\include command was previously used to quote the
           complete contents of a source file, now we want to use the
           command to include separate documentation.
           That is the functionality of the old \\input command
           which name we want to discard.

           \bold {We still need to use the \\input command to include
           plain text in new documentation for \l
           {reason}{compatibility reasons}}.

    \row
        \o \\quotefile \target quotefile-versus-include
        \o \\include
        \o Earlier, we have used the \\quotefile command to
           quote from file, i.e. quote parts from file, and the
           \\include command to quote the entire file. Since we now want
           \\include to include separate documentation, we change the use of
           \\quotefile to quote a complete source file.

           \bold {We still need to use the \\include command to quote
           the entire contents of a source file in new documentation
           for \l {reason}{compatibility reasons}}.

    \row
        \o \\quotefromfile \target quotefromfile-versus-quotefile
        \o \\quotefile
        \o Earlier, we have used the \\quotefile command to
           quote from file, i.e. quote parts from file. Since we now want
           that command to quote an entire file, we introduce the new
           \\quotefromfile command to quote from file.

           \bold {Use \l {quotefromfile}{\\quotefromfile} to quote
           parts from a source file in new documentation}.

    \row
        \o \\o \target o-versus-i
        \o \\i
        \o Earlier we used the \\i command to indicate list items
           and table items. Since we now want the \\i command to render
           in italic instead, we introduce the new \\o command for
           this purpose.

           \bold {Use \l {o}{\\o} to indicate list and table items in
           new documentation}.

    \row
        \o \\quotation \target quotation-versus-quote
        \o \\quote
        \o These commands are equivalent, and represent a simple name
          change.

          \bold {Use \l {quotation}{\\quotation} in new
          documentation}.

    \row
        \o \\image \target image-versus-img
        \o \\img
        \o These commands are equivalent, and represent a simple name
           change.

           \bold {Use \l {image}{\\image} in new documentation}.
