+ \class Q3Accel
+ \brief The Q3Accel class handles keyboard accelerator and shortcut keys.
+
+ \compat
+
+ A keyboard accelerator triggers an action when a certain key
+ combination is pressed. The accelerator handles all keyboard
+ activity for all the children of one top-level widget, so it is
+ not affected by the keyboard focus.
+
+ In most cases, you will not need to use this class directly. Use
+ the QAction class to create actions with accelerators that can be
+ used in both menus and toolbars. If you're only interested in
+ menus use Q3MenuData::insertItem() or Q3MenuData::setAccel() to make
+ accelerators for operations that are also available on menus. Many
+ widgets automatically generate accelerators, such as QAbstractButton,
+ QGroupBox, QLabel (with QLabel::setBuddy()), QMenuBar, and QTabBar.
+ Example:
+ \snippet doc/src/snippets/code/src_qt3support_other_q3accel.cpp 0
+
+ A Q3Accel contains a list of accelerator items that can be
+ manipulated using insertItem(), removeItem(), clear(), key() and
+ findKey().
+
+ Each accelerator item consists of an identifier and a \l
+ QKeySequence. A single key sequence consists of a keyboard code
+ combined with modifiers (Qt::SHIFT, Qt::CTRL, Qt::ALT, or
+ Qt::UNICODE_ACCEL). For example, Qt::CTRL + Qt::Key_P could be a shortcut
+ for printing a document. As an alternative, use Qt::UNICODE_ACCEL with the
+ unicode code point of the character. For example, Qt::UNICODE_ACCEL
+ + 'A' gives the same accelerator as Qt::Key_A.
+
+ When an accelerator key is pressed, the accelerator sends out the
+ signal activated() with a number that identifies this particular
+ accelerator item. Accelerator items can also be individually
+ connected, so that two different keys will activate two different
+ slots (see connectItem() and disconnectItem()).
+
+ The activated() signal is \e not emitted when two or more
+ accelerators match the same key. Instead, the first matching
+ accelerator sends out the activatedAmbiguously() signal. By
+ pressing the key multiple times, users can navigate between all
+ matching accelerators. Some standard controls like QPushButton and
+ QCheckBox connect the activatedAmbiguously() signal to the
+ harmless setFocus() slot, whereas activated() is connected to a
+ slot invoking the button's action. Most controls, like QLabel and
+ QTabBar, treat activated() and activatedAmbiguously() as
+ equivalent.
+
+ Use setEnabled() to enable or disable all the items in an
+ accelerator, or setItemEnabled() to enable or disable individual
+ items. An item is active only when both the Q3Accel and the item
+ itself are enabled.
+
+ The function setWhatsThis() specifies a help text that appears
+ when the user presses an accelerator key in What's This mode.
+
+ The accelerator will be deleted when \e parent is deleted,
+ and will consume relevant key events until then.
+
+ Please note that the accelerator
+ \snippet doc/src/snippets/code/src_qt3support_other_q3accel.cpp 1
+ can be triggered with both the 'M' key, and with Shift+M,
+ unless a second accelerator is defined for the Shift+M
+ combination.
+
+
+ Example:
+ \snippet doc/src/snippets/code/src_qt3support_other_q3accel.cpp 2
+
+ \sa QKeyEvent QWidget::keyPressEvent()
+ QAbstractButton::setAccel() QLabel::setBuddy() QKeySequence

+ extensible.
+
+ Use URIs in Unicode form so that the user can comfortably edit and
+ view them. For use in HTTP or other protocols, use the correctly
+ escaped ASCII form.
+
+ You can convert a list of file names to file URIs using
+ setFileNames(), or into human-readable form with setUnicodeUris().
+
+ Static functions are provided to convert between filenames and
+ URIs; e.g. uriToLocalFile() and localFileToUri(). Static functions
+ are also provided to convert URIs to and from human-readable form;
+ e.g. uriToUnicodeUri() and unicodeUriToUri().

+ \class Q3MimeSourceFactory
+ \brief The Q3MimeSourceFactory class is an extensible provider of mime-typed data.
+
+ \compat
+
+ A Q3MimeSourceFactory provides an abstract interface to a
+ collection of information. Each piece of information is
+ represented by a QMimeSource object which can be examined and
+ converted to concrete data types by functions such as
+ Q3ImageDrag::canDecode() and Q3ImageDrag::decode().
+
+ The base Q3MimeSourceFactory can be used in two ways: as an
+ abstraction of a collection of files or as specifically stored
+ data. For it to access files, call setFilePath() before accessing
+ data. For stored data, call setData() for each item (there are
+ also convenience functions, e.g. setText(), setImage() and
+ setPixmap(), that simply call setData() with appropriate
+ parameters).
+
+ The rich text widgets, QTextEdit and QTextBrowser, use
+ Q3MimeSourceFactory to resolve references such as images or links
+ within rich text documents. They either access the default factory
+ (see \l{defaultFactory()}) or their own. Other classes that are
+ capable of displaying rich text (such as QLabel, QWhatsThis or
+ QMessageBox) always use the default factory.
+
+ A factory can also be used as a container to store data associated
+ with a name. This technique is useful whenever rich text contains
+ images that are stored in the program itself, not loaded from the
+ hard disk. Your program may, for example, define some image data
+ as:
+ \snippet doc/src/snippets/code/src_qt3support_other_q3mimefactory.cpp 0
+
+ To be able to use this image within some rich text, for example
+ inside a QLabel, you must create a QImage from the raw data and
+ insert it into the factory with a unique name:
+ \snippet doc/src/snippets/code/src_qt3support_other_q3mimefactory.cpp 1
+
+ Now you can create a rich text QLabel with
+
+ \snippet doc/src/snippets/code/src_qt3support_other_q3mimefactory.cpp 2
+
+ When no longer needed, you can clear the data from the factory:
+
+ \snippet doc/src/snippets/code/src_qt3support_other_q3mimefactory.cpp 3

+ specified in the html file itself. "html" or "htm" will be treated
+ as text encoded in the encoding specified by the html meta tag, if
+ none could be found, the charset of the mime type will be used.
+ The text subtype ("html", "plain", or "xml") does not affect the

+ is not sufficient for your problem domain, you can inherit

+ *

+
+/*
+ * These are the data structures needed to scan
+ * convert regions. Two different scan conversion
+ * methods are available -- the even-odd method, and
+ * the winding number method.
+ * The even-odd rule states that a point is inside
+ * the polygon if a ray drawn from that point in any
+ * direction will pass through an odd number of
+ * path segments.
+ * By the winding number rule, a point is decided
+ * to be inside the polygon if a ray drawn from that
+ * point in any direction passes through a different
+ * number of clockwise and counterclockwise path
+ * segments.
+ *
+ * These data structures are adapted somewhat from
+ * the algorithm in (Foley/Van Dam) for scan converting
+ * polygons.
+ * The basic algorithm is to start at the top (smallest y)
+ * of the polygon, stepping down to the bottom of
+ * the polygon by incrementing the y coordinate. We
+ * keep a list of edges which the current scanline crosses,
+ * sorted by x. This list is called the Active Edge Table (AET)
+ * As we change the y-coordinate, we update each entry in
+ * in the active edge table to reflect the edges new xcoord.
+ * This list must be sorted at each scanline in case
+ * two edges intersect.
+ * We also keep a data structure known as the Edge Table (ET),
+ * which keeps track of all the edges which the current
+ * scanline has not yet reached. The ET is basically a
+ * list of ScanLineList structures containing a list of
+ * edges which are entered at a given scanline. There is one
+ * ScanLineList per scanline at which an edge is entered.
+ * When we enter a new edge, we move it from the ET to the AET.
+ *
+ * From the AET, we can implement the even-odd rule as in
+ * (Foley/Van Dam).
+ * The winding number rule is a little trickier. We also
+ * keep the EdgeTableEntries in the AET linked by the
+ * nextWETE (winding EdgeTableEntry) link. This allows
+ * the edges to be linked just as before for updating
+ * purposes, but only uses the edges linked by the nextWETE
+ * link as edges representing spans of the polygon to
+ * drawn (as with the even-odd rule).

+ \class Q3Process
+
+ \brief The Q3Process class is used to start external programs and
+ to communicate with them.
+
+ \compat
+
+ You can write to the started program's standard input, and can
+ read the program's standard output and standard error. You can
+ pass command line arguments to the program either in the
+ constructor or with setArguments() or addArgument(). The program's
+ working directory can be set with setWorkingDirectory(). If you
+ need to set up environment variables pass them to the start() or
+ launch() functions (see below). The processExited() signal is
+ emitted if the program exits. The program's exit status is
+ available from exitStatus(), although you could simply call
+ normalExit() to see if the program terminated normally.
+
+ There are two different ways to start a process. If you just want
+ to run a program, optionally passing data to its standard input at
+ the beginning, use one of the launch() functions. If you want full
+ control of the program's standard input (especially if you don't
+ know all the data you want to send to standard input at the
+ beginning), use the start() function.
+
+ If you use start() you can write to the program's standard input
+ using writeToStdin() and you can close the standard input with
+ closeStdin(). The wroteToStdin() signal is emitted if the data
+ sent to standard input has been written. You can read from the
+ program's standard output using readStdout() or readLineStdout().
+ These functions return an empty QByteArray if there is no data to
+ read. The readyReadStdout() signal is emitted when there is data
+ available to be read from standard output. Standard error has a
+ set of functions that correspond to the standard output functions,
+ i.e. readStderr(), readLineStderr() and readyReadStderr().
+
+ If you use one of the launch() functions the data you pass will be
+ sent to the program's standard input which will be closed once all
+ the data has been written. You should \e not use writeToStdin() or
+ closeStdin() if you use launch(). If you need to send data to the
+ program's standard input after it has started running use start()
+ instead of launch().
+
+ Both start() and launch() can accept a string list of strings each
+ of which has the format, key=value, where the keys are the names
+ of environment variables.
+
+ You can test to see if a program is running with isRunning(). The
+ program's process identifier is available from
+ processIdentifier(). If you want to terminate a running program
+ use tryTerminate(), but note that the program may ignore this. If
+ you \e really want to terminate the program, without it having any
+ chance to clean up, you can use kill().
+
+ Although you may need quotes for a file named on the command line
+ (e.g. if it contains spaces) you shouldn't use extra quotes for
+ arguments passed to addArgument() or setArguments().
+
+ The readyReadStdout() signal is emitted when there is new data on
+ standard output. This happens asynchronously: you don't know if
+ more data will arrive later.
+
+ In the above example you could connect the processExited() signal
+ to the slot UicManager::readFromStdout() instead. If you do so,
+ you will be certain that all the data is available when the slot
+ is called. On the other hand, you must wait until the process has
+ finished before doing any processing.
+
+ Note that if you are expecting a lot of output from the process,
+ you may hit platform-dependent limits to the pipe buffer size. The
+ solution is to make sure you connect to the output, e.g. the
+ readyReadStdout() and readyReadStderr() signals and read the data
+ as soon as it becomes available.
+
+ Please note that Q3Process does not emulate a shell. This means that
+ Q3Process does not do any expansion of arguments: a '*' is passed as a '*'
+ to the program and is \e not replaced by all the files, a '$HOME' is also
+ passed literally and is \e not replaced by the environment variable HOME
+ and the special characters for IO redirection ('>', '|', etc.) are also
+ passed literally and do \e not have the special meaning as they have in a
+ shell.
+
+ Also note that Q3Process does not emulate a terminal. This means that
+ certain programs which need direct terminal control, do not work as
+ expected with Q3Process. Such programs include console email programs (like
+ pine and mutt) but also programs which require the user to enter a password
+ (like su and ssh).
+
+ \section1 Notes for Windows users
+
+ Some Windows commands, for example, \c dir, are not provided by
+ separate applications, but by the command interpreter.
+ If you attempt to use Q3Process to execute these commands directly
+ it won't work. One possible solution is to execute the command
+ interpreter itself (\c cmd.exe on some Windows systems), and ask
+ the interpreter to execute the desired command.
+
+ Under Windows there are certain problems starting 16-bit applications
+ and capturing their output. Microsoft recommends using an intermediate
+ application to start 16-bit applications.
