\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 \\enum \target enum
\o \bold {The \\enum command allows you to document a C++ enum.}
The command follows \l {topical argument}{the general

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,
TopRightCorner = 0x00001,
BottomLeftCorner = 0x00002,
BottomRightCorner = 0x00003

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 will be rendered as \quotation \raw HTMLflat : bool
\endraw This property holds whether the border is disabled. This property's default is false. Access functions: \list \o \bold { bool isFlat () const} \o \bold { void setFlat ( bool )} \endlist \endquotation in qpushbutton.html.

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 = "Home"
\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 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 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.
\row
\o \bold generateindex \target generateindex
\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 headerdirs \target headerdirs
\o \bold {The \c headerdirs variable specifies the directories
containing the header files associated with the \c .cpp source
files used in the documentation.}
For example:
\code
headerdirs = $QTDIR/src \
$QTDIR/extensions/activeqt \
$QTDIR/extensions/motif \
$QTDIR/tools/designer/src/lib/extension \
$QTDIR/tools/designer/src/lib/sdk \
$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.
See also \l headers and \l headers.fileextensions.
\row
\o \bold headers \target headers
\o \bold {The \c headers variable allows you to specify individual
header files in addition to those located in the directories
specified by the \l {headerdirs}{\c headerdirs} variable.}
For example:
\code
headers = $QTDIR/src/gui/widgets/qlineedit.h \
$QTDIR/src/gui/widgets/qpushbutton.h
\endcode
When processing the \c headers variable, QDoc behaves in the
same way as it does when processing the \l {headerdirs}{\c
headerdirs} variable. For more information, see the \l
{headerdirs}{\c headerdirs} variable.
See also \l headerdirs.
\row
\o \bold headers.fileextensions \target headers.fileextensions
\o \bold {The \c headers.fileextensions variable specify the
extension used by the headers.}
When processing the header files specified in the \l
{headerdirs}{\c headerdirs} variable, QDoc will only read
the files with the fileextensions specified in the \c
headers.fileextensions variable. In this way QDoc avoid
spending time reading irrelevant files.
The default extensions are *.ch, *.h, *.h++, *.hh, *.hpp
and *.hxx.
The extensions are given as standard wildcard expressions.
You can add a file extension to the filter using '+='. For
example:
\code
header.fileextensions += *.H
\endcode
\warning The above assignment may not work as described.
See also \l headerdirs.
\row
\o \bold imagedirs \target imagedirs
\o \bold {The \c imagedirs variable specifies the directories
containing the images used in the documentation.}
The \l {images}{\c images} and \c imagedirs variables are
used by the \l {image}{\\image} and \l
{inlineimage}{\\inlineimage} commands. If both the \l
{images}{\c images} and \c imagedirs variables are defined,
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:
\code
imagedirs = $QTDIR/doc/src/images \
$QTDIR/examples
images = $QTDIR/doc/src/images/calculator-example.png
\endcode
When processing
\code
\image calculator-example.png
\endcode
QDoc will then see if there exists a file called
calculator-example.png listed as a value in the \c images
variable. If it doesn't, it will search in the \c imagedirs
variable, and first see if there exists a file called
\code
$QTDIR/doc/src/images/calculator-example.png
\endcode
If it doesn't, QDoc will look for a file called
\code
$QTDIR/examples/calculator-example.png
\endcode
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.
\warning The \l {images.fileextensions}{\c
images.fileextensions} variable's functionality is
preliminay since QDoc at this point only support HTML.
See also \l images and \l images.fileextensions.
\row
\o \bold images \target images
\o \bold {The \c images variable allows you to specify individual
image files in addition to those located in the directories
specified by the \l {imagedirs}{\c imagedirs} variable.}
For example:
\code
images = $QTDIR/doc/src/images/calculator-example.png
\endcode
When processing the \c images variable, QDoc behaves in the
same way as it does when processing the \l {imagedirs}{\c
imagedirs} variable. For more information, see the \l
{imagedirs}{\c imagedirs} variable.
See also \l imagedirs and \l images.fileextensions.
\row
\o \bold images.fileextensions \target images.fileextensions
\o \bold {The images.fileextensions variable filters the files within
an image directory.}
The variable's values (the extensions) are given as
standard wildcard expressions. The general syntax is: \tt
{images.fileextensions.\i{format} = *.\i{extension}}.
The idea is to enable different image format for different
output format. For example:
\code
images.fileextensions.HTML = *.png
images.fileextensions.LOUT = *.eps
\endcode
Then, when processing the \l {image}{\\image} and \l
{inlineimage}{\\inlineimage} commands, QDoc will only
search for files with extensions specified in the output
format's associated image extension variable.
\warning This is preliminary functionality since QDoc at
this point only support HTML.
The default extensions for HTML are *.png, *.jpg, *.jpeg
and *.gif.
You can add a file extension to the filter using '+='. For
example:
\code
images.fileextensions.HTML += *.eps
\endcode
See also \l imagedirs and \l images.
\row
\o \bold language \target language
\o \bold {The \c language variable specifies the language of the
source code that is used in the documentation.}
Currently, C++ is the only language that QDoc
understands. It is also the default language, and doesn't
really need to be specified. But for example in \l
qt.qdocconf:
\code
language = Cpp
\endcode
identifies the language of the Qt source code as C++.
\row
\o \bold macro \target macro
\o \bold {The \c macro variable can be used to create your
own QDoc commands.}
The general syntax is \tt {macro.\i{command} =
"\i{definition}}". The definition can be described using
QDoc syntax. In addition it is possible to provide an HTML
definition by appending .HTML to the variable.
For example in \l qt.qdocconf:
\code
macro.gui = "\\bold"
macro.raisedaster.HTML = "*"
\endcode
makes sure that the \\gui command renders its argument using a
bold font, and that \\raisedaster renders a '*'.
\row
\o \bold outputdir \target outputdir
\o \bold {The \c outputdir variable specifies the directory
where QDoc will put the generated documentation.}
In qt.qdocconf:
\code
outputdir = $QTDIR/doc/html
\endcode
locates the generated Qt reference documentation in
$QTDIR/doc/html. For example, the documentation of the
QWidget class is located in
\code
$QTDIR/doc/html/qwidget.html
\endcode
The associated images will be put in an \c images subdirectory.
\warning When running QDoc multiple times using the same output
directory, all files from the previous run will be lost.
\row
\o \bold outputformats \target outputformats
\o \bold {The \c outputformats variable specifies the format of
the generated documentation.}
Currently, QDoc only supports the HTML format. It is also
the default format, and doesn't need to be specified.
\row
\o \bold qhp \target qhp
\o \bold{The \c qhp variable is used to define the information to be
written out to Qt Help Project (\c{qhp}) files.}
See the \l{Creating Help Project Files} chapter for information
about this process.
\row
\o \bold slow \target slow
\o \bold {The \c slow variable specifies whether QDoc should do
time-consuming processing, such as syntax highlighting.}
By default, this setting is false.
Example:
\code
slow = true
\endcode
Another way to turn on "slowness" is to invoke QDoc with the
\c -slow command-line option.
\row
\o \bold sourcedirs \target sourcedirs
\o \bold {The \c sourcedirs variable specifies the directories
containing the \c .cpp or \c .qdoc files used in
the documentation.}
For example in \l qt.qdocconf
\code
sourcedirs = $QTDIR/src \
$QTDIR/doc/src \
$QTDIR/extensions/activeqt \
$QTDIR/extensions/motif \
$QTDIR/tools/designer/src/lib/extension \
$QTDIR/tools/designer/src/lib/sdk \
$QTDIR/tools/designer/src/lib/uilib
\endcode
When executed, the first QDoc will do is to read through
the headers specified in the \l {header}{\c header}
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 sources and \c sourcedirs variables are
defined, QDoc will read through both, first \l {sources}{\c
sources} then \c sourcedirs.
In the specified directories, QDoc will only read the files
with the fileextensions specified in the \l
{sources.fileextensions}{\c sources.fileextensions}
variable. The default extensions are *.c++, *.cc, *.cpp and
*.cxx. The files specified by \l {sources}{\c sources} will
be read independent of their fileextensions.
See also \l sources and \l sources.fileextensions.
\row
\o \bold sources \target sources
\o \bold {The \c sources variable allows you to specify
individual source files in addition to those located in the
directories specified by the \l {sourcedir}{\c sourcedir}
variable.}
For example:
\code
sources = $QTDIR/src/gui/widgets/qlineedit.cpp \
$QTDIR/src/gui/widgets/qpushbutton.cpp
\endcode
When processing the \c sources variable, QDoc behaves in the
same way as it does when processing the \l {sourcedirs}{\c
sourcedirs} variable. For more information, see the \l
{sourcedirs}{\c sourcedirs} variable.
See also \l sourcedirs.
\row
\o \bold sources.fileextensions \target sources.fileextensions
\o \bold {The \c sources.fileextensions variable filters the
files within a source directory.}
When processing the source files specified in the \l
{sourcedirs}{\c sourcedirs} variable, QDoc will only read
the files with the fileextensions specified in the \c
sources.fileextensions variable. In this way QDoc avoid
spending time reading irrelevant files.
The default extensions are *.c++, *.cc, *.cpp and *.cxx.
The extensions are given as standard wildcard expressions.
You can add a file extension to the filter using '+='. For
example:
\code
sources.fileextensions += *.CC
\endcode
\warning The above assignment may not work as described.
See also \l sourcedirs and \l sources.
\row
\o \bold spurious \target spurious
\o \bold {The \c spurious variable excludes specified
QDoc warnings from the output.}
The warnings are specified using standard wildcard
expressions. For example:
\code
spurious = "Cannot find .*" \
"Missing .*"
\endcode
makes sure that warnings matching either of these
expressions, will not be part of the output when running
QDoc. For example would the following warning be omitted
from the output:
\code
qt-4.0/src/opengl/qgl_mac.cpp:156: Missing parameter name
\endcode
\row
\o \bold tabsize \target tabsize
\o \bold {The \c tabsize variable defines the size of a tab
character.}
For example:
\code
tabsize = 4
\endcode
will give the tab character the size of 4 spaces.
The default value of the variable is 8, and doesn't need to
be specified.
\row
\o \bold tagfile \target tagfile
\o \bold{The \c tagfile variable specifies the Doxygen tag file to be written
when HTML is generated.}
\row
\o \bold version \target version
\o \bold {The \c version variable specifies the version number of the
documented software.}
For example:
\code
version = 4.0.1
\endcode
When a version number is specified (using the \tt{\l
version} or \tt {\l versionsym} variables in a \c .qdocconf
file), it is accessible through the corresponding \\version
command for use in the documentation.
\warning The \\version command's functionality is not
fully implemented; currently it only works within raw HTML
code.
See also \l versionsym.
\row
\o \bold versionsym \target versionsym
\o \bold {The \c versionsym variable specifies a C++
preprocessor symbol that defines the version number
of the documented software.}
For example in \l qt.qdocconf:
\code
versionsym = QT_VERSION_STR
\endcode
QT_VERSION_STR is defined in qglobal.h as follows
\code
#define QT_VERSION_STR "4.0.1"
\endcode
When a version number is specified (using the \tt{\l
version} or \tt {\l versionsym} variables in a \c .qdocconf
file), it is accessible through the corresponding \\version
command for use in the documentation.
\warning The \\version command's functionality is not fully
implemented; currently it only works within raw HTML code.

\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
\endcode

The C++ specific configuration variables are provided to avoid
erroneous documentation due to non-standard C++ constructs.

\header
\o Variable
\o Description
\row
\o \bold Cpp.ignoredirectives \target Cpp.ignoredirectives
\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 \
Q_DECLARE_PUBLIC \
Q_DISABLE_COPY \
Q_DUMMY_COMPARISON_OPERATOR \
Q_ENUMS \
Q_FLAGS \
Q_INTERFACES \
__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
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.ignoretokens = QAXFACTORY_EXPORT \
QM_EXPORT_CANVAS \
...
Q_COMPAT_EXPORT \
Q_CORE_EXPORT \
Q_EXPLICIT \
Q_EXPORT \
...
Q_TYPENAME \
Q_XML_EXPORT
\endcode
makes sure that when processing the code below, for
example, QDoc will simply ignore the 'Q_CORE_EXPORT'
expression:
\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
Regarding the Q_OBJECT, Q_ENUMS and Q_FLAGS macros; see the
documentation of the \tt {\l Cpp.ignoredirectives}
variable.

\title HTML Specific Variables
The HTML specific configuration variables define the generated
documentation's style, or define the contents of the
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 = "\n" \
...
"

\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:
