+ \class QCopChannel
+ \ingroup qws
+
+ \brief The QCopChannel class provides communication capabilities
+ between clients in \l{Qt for Embedded Linux}.
+
+ Note that this class is only available in \l{Qt for Embedded Linux}.
+
+ The Qt COmmunication Protocol (QCOP) is a many-to-many protocol
+ for transferring messages across registered channels. A channel is
+ registered by name, and anyone who wants to can listen to the
+ channel as well as send messages through it. The QCOP protocol
+ allows clients to communicate both within the same address space
+ and between different processes.
+
+ To send messages to a given channel, QCopChannel provides the
+ static send() function. Using this function alone, the messages
+ are queued until Qt re-enters the event loop. To immediately flush
+ all queued messages to the registered listeners, call the static
+ flush() function.
+
+ To listen to the traffic on a given channel, you typically
+ instantiate a QCopChannel object for the given channel and connect
+ to its received() signal that is emitted whenever there is
+ incoming data. Use the static isRegistered() function to query
+ the server for the existence of a given channel. QCopChannel
+ provides the channel() function returning the name of this
+ QCopChannel object's channel.
+
+ In additon, QCopChannel provides the virtual receive() function
+ that can be reimplemented to filter the incoming messages and
+ data. The default implementation simply emits the received()
+ signal.

+ \class QDecoration
+ \ingroup qws
+
+ \brief The QDecoration class is a base class for window
+ decorations in Qt for Embedded Linux
+
+ Note that this class is non-portable and only available in
+ \l{Qt for Embedded Linux}.
+
+ \l{Qt for Embedded Linux} provides window management of top level windows
+ and several ready made decorations (i.e., \c Default, \c Styled
+ and \c Windows). Custom decorations can be implemented by
+ subclassing the QDecoration class and creating a decoration plugin
+ (derived from QDecorationPlugin). The default
+ implementation of the QDecorationFactory class will automatically
+ detect the plugin, and load the decoration into the application at
+ run-time using Qt's \l {How to Create Qt Plugins}{plugin
+ system}. To actually apply a decoration, use the
+ QApplication::qwsSetDecoration() function.
+
+ When creating a custom decoration, implement the paint() function
+ to paint the border and title decoration, and the region()
+ function to return the regions the decoration
+ occupies. Reimplement the regionClicked() and
+ regionDoubleClicked() functions to respond to mouse clicks (the
+ default implementations responds to (single) clicks on items in a
+ widget's system menu and double clicks on a widget's title).
+
+ QDecoration provides the DecorationRegion enum that describes the
+ various regions of the window decoration, and the regionAt()
+ function to determine the region containing a given point. The
+ QDecoration class also provides the DecorationState enum
+ describing the state of a given region, e.g. whether it is active
+ or not.
+
+ In addition, it is possible to build the system menu for a given
+ top level widget using the buildSysMenu() function; whenever an
+ action in this menu is triggered, the menuTriggered() function is
+ called automatically.
+
+ Finally, the QDecoration class provides a couple of static
+ functions, startMove() and startResize(), which start a move or
+ resize action by making the appropriate decoration region active
+ and grabbing the mouse input.

+ \class QDirectPainter
+ \ingroup multimedia
+ \ingroup qws
+
+ \brief The QDirectPainter class provides direct access to the
+ underlying hardware in Qt for Embedded Linux.
+
+ Note that this class is only available in \l{Qt for Embedded Linux}.
+
+ QDirectPainter allows a client application to reserve a region of
+ the framebuffer and render directly onto the screen. There are two
+ ways of using the QDirectPainter class: You can either reserve a
+ region using the provided static functions, or you can instantiate
+ an object and make use of its more dynamic API.
+
+ \tableofcontents
+
+ \section1 Dynamic Allocation
+
+ By instantiating a QDirectPainter object using the default
+ QDirectPainter::NonReserved surface flag, the client application
+ only gets some control over the reserved region, i.e., it can
+ still render directly onto the screen but the allocated region may
+ change (for example, if a window with a higher focus requests
+ parts of the same region). The currently allocated region can be
+ retrieved using the allocatedRegion() function, while the
+ requestedRegion() function returns the originally reserved
+ region.
+
+
+ \section1 Static Allocation
+
+
+ Using the static approach, the client application gets complete
+ control over the reserved region, i.e., the affected region will
+ never be modified by the screen driver.
+
+ To create a static region, pass the QDirectPainter::Reserved
+ surface flag to the constructor. After the reserved region is
+ reported through regionChanged(), the allocated region will not
+ change, unless setRegion() is called.
+
+ If QDirectPainter::ReservedSynchronous is passed to the
+ constructor, calls to setRegion() will block until the region is
+ reserved, meaning that allocatedRegion() will be available immediately.
+ Note that in the current version setRegion() will cause the application
+ event loop to be entered, potentially causing reentrancy issues.
+
+ \section1 Rendering
+
+ To draw on a given region, the application must first get hold of
+ a pointer to the framebuffer. In most cases, this pointer can be
+ retrieved using the QDirectPainter::frameBuffer() function. But
+ note that if the current screen has subscreens, you must query the
+ screen driver instead to identify the correct subscreen. A pointer
+ to the current screen driver can always be retrieved using the
+ static QScreen::instance() function. Then use QScreen's \l
+ {QScreen::}{subScreenIndexAt()} and \l {QScreen::}{subScreens()}
+ functions to access the correct subscreen, and the subscreen's \l
+ {QScreen::}{base()} function to retrieve a pointer to the
+ framebuffer.
+
+ Depending on the hardware, it might be necessary to lock the
+ framebuffer for exclusive use while writing to it. This is
+ possible using the lock() and unlock() functions. Note that
+ calling lock() will prevent all other applications from working
+ until unlock() is called.
+
+ In addition, QDirectPainter provides several functions returning
+ information about the framebuffer: the linestep() function returns
+ the length (in bytes) of each scanline of the framebuffer while
+ the screenDepth(), screenWidth() and screenHeight() function
+ return the screen metrics.

+ \class QWSKeyboardHandler
+ \ingroup qws
+
+ \brief The QWSKeyboardHandler class is a base class for keyboard
+ drivers in Qt for Embedded Linux.
+
+ Note that this class is only available in \l{Qt for Embedded Linux}.
+
+ \l{Qt for Embedded Linux} provides ready-made drivers for several keyboard
+ protocols, see the \l{Qt for Embedded Linux Character Input}{character
+ input} documentation for details. Custom keyboard drivers can be
+ implemented by subclassing the QWSKeyboardHandler class and
+ creating a keyboard driver plugin (derived from
+ QKbdDriverPlugin). The default implementation of the
+ QKbdDriverFactory class will automatically detect the plugin, and
+ load the driver into the server application at run-time using Qt's
+ \l{How to Create Qt Plugins}{plugin system}.
+
+ The keyboard driver receives keyboard events from the system
+ device and encapsulates each event with an instance of the
+ QWSEvent class which it then passes to the server application (the
+ server is responsible for propagating the event to the appropriate
+ client). To receive keyboard events, a QWSKeyboardHandler object
+ will usually create a QSocketNotifier object for the given
+ device. The QSocketNotifier class provides support for monitoring
+ activity on a file descriptor. When the socket notifier receives
+ data, it will call the keyboard driver's processKeyEvent()
+ function to send the event to the \l{Qt for Embedded Linux} server
+ application for relaying to clients.
+
+
+ QWSKeyboardHandler also provides functions to control
+ auto-repetion of key sequences, beginAutoRepeat() and
+ endAutoRepeat(), and the transformDirKey() function enabling
+ transformation of arrow keys according to the display orientation.
+
+ \sa QKbdDriverPlugin, QKbdDriverFactory, {Qt for Embedded Linux Character Input}

+ \class QKbdDriverPlugin
+ \ingroup plugins
+ \ingroup qws
+
+ \brief The QKbdDriverPlugin class is an abstract base class for
+ keyboard driver plugins in Qt for Embedded Linux.
+
+ Note that this class is only available in \l{Qt for Embedded Linux}.
+
+ \l{Qt for Embedded Linux} provides ready-made drivers for several keyboard
+ protocols, see the \l{Qt for Embedded Linux Character Input}{character
+ input} documentation for details. Custom keyboard drivers can be
+ implemented by subclassing the QWSKeyboardHandler class and
+ creating a keyboard driver plugin.
+
+ A keyboard driver plugin can be created by subclassing
+ QKbdDriverPlugin and reimplementing the pure virtual keys() and
+ create() functions. By exporting the derived class using the
+ Q_EXPORT_PLUGIN2() macro, the default implementation of the
+ QKbdDriverFactory class will automatically detect the plugin and
+ load the driver into the server application at run-time. See
+ \l{How to Create Qt Plugins} for details.
+
+ \sa QKbdDriverFactory, QWSKeyboardHandler
+*/
+
+/*!
+ \fn QStringList QKbdDriverPlugin::keys() const
+
+ Implement this function to return the list of valid keys, i.e. the
+ keyboard drivers supported by this plugin.
+
+ \l{Qt for Embedded Linux} provides ready-made drivers for several keyboard

+ input} documentation for details.

+ \class QWSMouseHandler
+ \ingroup qws
+
+ \brief The QWSMouseHandler class is a base class for mouse drivers in
+ Qt for Embedded Linux.
+
+ Note that this class is only available in \l{Qt for Embedded Linux}.
+
+ \l{Qt for Embedded Linux} provides ready-made drivers for several mouse
+ protocols, see the \l{Qt for Embedded Linux Pointer Handling}{pointer
+ handling} documentation for details. Custom mouse drivers can be
+ implemented by subclassing the QWSMouseHandler class and creating
+ a mouse driver plugin (derived from QMouseDriverPlugin).
+ The default implementation of the QMouseDriverFactory class
+ will automatically detect the plugin, and load the driver into the
+ server application at run-time using Qt's \l {How to Create Qt
+ Plugins}{plugin system}.
+
+ The mouse driver receives mouse events from the system device and
+ encapsulates each event with an instance of the QWSEvent class
+ which it then passes to the server application (the server is
+ responsible for propagating the event to the appropriate
+ client). To receive mouse events, a QWSMouseHandler object will
+ usually create a QSocketNotifier object for the given device. The
+ QSocketNotifier class provides support for monitoring activity on
+ a file descriptor. When the socket notifier receives data, it will
+ call the mouse driver's mouseChanged() function to send the event
+ to the \l{Qt for Embedded Linux} server application for relaying to
+ clients.
+
+ If you are creating a driver for a device that needs calibration
+ or noise reduction, such as a touchscreen, use the
+ QWSCalibratedMouseHandler subclass instead to take advantage of
+ the calibrate() and clearCalibration() functions. The \l
+ {qws/mousecalibration}{Mouse Calibration}
+ demonstrates how to write a simple program using the mechanisms
+ provided by the QWSMouseHandler class to calibrate a mouse driver.
+
+ Note that when deriving from the QWSMouseHandler class, the
+ resume() and suspend() functions must be reimplemented to control
+ the flow of mouse input, i.e., the default implementation does
+ nothing. Reimplementations of these functions typically call the
+ QSocketNotifier::setEnabled() function to enable or disable the
+ socket notifier, respectively.
+
+ In addition, QWSMouseHandler provides the setScreen() function
+ that allows you to specify a screen for your mouse driver and the
+ limitToScreen() function that ensures that a given position is
+ within this screen's boundaries (changing the position if
+ necessary). Finally, QWSMouseHandler provides the pos() function
+ returning the current mouse position.

+
+ QWSCalibratedMouseHandler provides an implementation of the
+ calibrate() function to update the calibration parameters based on
+ coordinate mapping of the given calibration data. The calibration
+ data is represented by an QWSPointerCalibrationData object. The
+ linear transformation between device coordinates and screen
+ coordinates is performed by calling the transform() function

+
+ The calibration parameters are recalculated whenever calibrate()

+ time using the readCalibration() function (calibration parameters
+ are always read when the class is instantiated). Note that the
+ calibration parameters is written to and read from the file

+

+
+ \brief The QMouseDriverFactory class creates mouse drivers in
+ Qt for Embedded Linux.
+
+ Note that this class is only available in \l{Qt for Embedded Linux}.
+
+ QMouseDriverFactory is used to detect and instantiate the
+ available mouse drivers, allowing \l{Qt for Embedded Linux} to load the
+ preferred driver into the server application at runtime. The
+ create() function returns a QWSMouseHandler object representing
+ the mouse driver identified by a given key. The valid keys
+ (i.e. the supported drivers) can be retrieved using the keys()
+ function.
+
+ \l{Qt for Embedded Linux} provides several built-in mouse drivers. In
+ addition, custom mouse drivers can be added using Qt's plugin
+ mechanism, i.e. by subclassing the QWSMouseHandler class and
+ creating a mouse driver plugin (QMouseDriverPlugin). See the
+ \l{Qt for Embedded Linux Pointer Handling}{pointer handling}
+ documentation for details.

+ \brief The QMouseDriverPlugin class is an abstract base class for
+ mouse driver plugins in Qt for Embedded Linux.
+
+ Note that this class is only available in \l{Qt for Embedded Linux}.
+
+ \l{Qt for Embedded Linux} provides ready-made drivers for several mouse
+ protocols, see the \l{Qt for Embedded Linux Pointer Handling}{pointer
+ handling} documentation for details. Custom mouse drivers can be
+ implemented by subclassing the QWSMouseHandler class and creating
+ a mouse driver plugin.
+
+ A mouse driver plugin can be created by subclassing
+ QMouseDriverPlugin and reimplementing the pure virtual keys() and
+ create() functions. By exporting the derived class using the
+ Q_EXPORT_PLUGIN2() macro, The default implementation of the
+ QMouseDriverFactory class will automatically detect the plugin and
+ load the driver into the server application at run-time. See \l
+ {How to Create Qt Plugins} for details.

+
+ \class QWSTslibMouseHandler
+ \ingroup qws
+
+ \brief The QWSTslibMouseHandler class implements a mouse driver
+ for the Universal Touch Screen Library, tslib.
+
+ QWSTslibMouseHandler inherits the QWSCalibratedMouseHandler class,
+ providing calibration and noise reduction functionality in
+ addition to generating mouse events, for devices using the
+ Universal Touch Screen Library.
+
+ To be able to compile this mouse handler, \l{Qt for Embedded Linux}
+ must be configured with the \c -qt-mouse-tslib option, see the
+ \l{Pointer Handling} documentation for details. In addition, the tslib
+ headers and library must be present in the build environment. The
+ tslib sources can be downloaded from \l
+ {http://tslib.berlios.de/}. Use the \c -L and \c -I options
+ with \c configure to explicitly specify the location of the
+ library and its headers:
+
+ \snippet doc/src/snippets/code/src_gui_embedded_qmousetslib_qws.cpp 0
+
+ In order to use this mouse handler, tslib must also be correctly
+ installed on the target machine. This includes providing a \c
+ ts.conf configuration file and setting the necessary environment
+ variables, see the README file provided with tslib for details.
+
+ The ts.conf file will usually contain the following two lines
+
+ \snippet doc/src/snippets/code/src_gui_embedded_qmousetslib_qws.cpp 1
+
+ To make \l{Qt for Embedded Linux} explicitly choose the tslib mouse
+ handler, set the QWS_MOUSE_PROTO environment variable.
+
+ \sa {Pointer Handling}, {Qt for Embedded Linux}

+ \class QScreenCursor
+ \ingroup qws
+
+ \brief The QScreenCursor class is a base class for screen cursors
+ in Qt for Embedded Linux.
+
+ Note that this class is non-portable, and that it is only
+ available in \l{Qt for Embedded Linux}.
+
+ QScreenCursor implements a software cursor, but can be subclassed
+ to support hardware cursors as well. When deriving from the
+ QScreenCursor class it is important to maintain the cursor's
+ image, position, hot spot (the point within the cursor's image
+ that will be the position of the associated mouse events) and
+ visibility as well as informing whether it is hardware accelerated
+ or not.
+
+ Note that there may only be one screen cursor at a time. Use the
+ static instance() function to retrieve a pointer to the current
+ screen cursor. Typically, the cursor is constructed by the QScreen
+ class or one of its descendants when it is initializing the
+ device; the QScreenCursor class should never be instantiated
+ explicitly.
+
+ Use the move() function to change the position of the cursor, and
+ the set() function to alter its image or its hot spot. In
+ addition, you can find out whether the cursor is accelerated or
+ not, using the isAccelerated() function, and the boundingRect()
+ function returns the cursor's bounding rectangle.
+
+ The cursor's appearance can be controlled using the isVisible(),
+ hide() and show() functions; alternatively the QWSServer class
+ provides some means of controlling the cursor's appearance using
+ the QWSServer::isCursorVisible() and QWSServer::setCursorVisible()
+ functions.
+
+ \sa QScreen, QWSServer

+/*!
+ \class QScreen
+ \ingroup qws
+
+ \brief The QScreen class is a base class for screen drivers in
+ Qt for Embedded Linux.
+
+ Note that this class is only available in \l{Qt for Embedded Linux}.
+
+ \l{Qt for Embedded Linux} provides ready-made drivers for several screen
+ protocols, see the \l{Qt for Embedded Linux Display Management}{display
+ management} documentation for details. Custom screen drivers can
+ be implemented by subclassing the QScreen class and creating a
+ screen driver plugin (derived from QScreenDriverPlugin). The
+ default implementation of the QScreenDriverFactory class
+ will automatically detect the plugin, and load the driver into the
+ server application at run-time using Qt's \l {How to Create Qt
+ Plugins}{plugin system}.
+
+ When rendering, the default behavior is for each
+ client to render its widgets as well as its decorations into
+ memory, while the server copies the memory content to the device's
+ framebuffer using the screen driver. See the \l{Qt for Embedded Linux
+ Architecture} overview for details (note that it is possible for
+ the clients to manipulate and control the underlying hardware
+ directly as well).
+
+ Starting with Qt 4.2, it is also possible to add an
+ accelerated graphics driver to take advantage of available
+ hardware resources. See the \l{Adding an Accelerated Graphics
+ Driver to Qt for Embedded Linux} documentation for details.
+
+ \tableofcontents
+
+ \section1 Framebuffer Management
+
+ When a \l{Qt for Embedded Linux} application starts running, it
+ calls the screen driver's connect() function to map the
+ framebuffer and the accelerated drivers that the graphics card
+ control registers. The connect() function should then read out the
+ parameters of the framebuffer and use them as required to set this
+ class's protected variables.
+
+ The initDevice() function can be reimplemented to initialize the
+ graphics card. Note, however, that connect() is called \e before
+ the initDevice() function, so, for some hardware configurations,
+ some of the initialization that would normally be done in the
+ initDevice() function might have to be done in the connect()
+ function.
+
+ Likewise, just before a \l{Qt for Embedded Linux} application
+ exits, it calls the screen driver's disconnect() function. The
+ server application will in addition call the shutdownDevice()
+ function before it calls disconnect(). Note that the default
+ implementation of the shutdownDevice() function only hides the
+ mouse cursor.
+
+ QScreen also provides the save() and restore() functions, making
+ it possible to save and restore the state of the graphics
+ card. Note that the default implementations do nothing. Hardware
+ screen drivers should reimplement these functions to save (and
+ restore) its registers, enabling switching between virtual
+ consoles.
+
+ In addition, you can use the base() function to retrieve a pointer
+ to the beginning of the framebuffer, and the region() function to
+ retrieve the framebuffer's region. Use the onCard() function to
+ determine whether the framebuffer is within the graphics card's
+ memory, and the totalSize() function to determine the size of the
+ available graphics card memory (including the screen). Finally,
+ you can use the offset() function to retrieve the offset between
+ the framebuffer's coordinates and the application's coordinate
+ system.
+
+ \section1 Palette Management
+
+ QScreen provides several functions to retrieve information about
+ the color palette: The clut() function returns a pointer to the
+ color lookup table (i.e. its color palette). Use the numCols()
+ function to determine the number of entries in this table, and the
+ alloc() function to retrieve the palette index of the color that
+ is the closest match to a given RGB value.
+
+ To determine if the screen driver supports a given color depth,
+ use the supportsDepth() function that returns true of the
+ specified depth is supported.
+
+ \section1 Drawing on Screen
+
+ When a screen update is required, the \l{Qt for Embedded Linux} server runs
+ through all the top-level windows that intersect with the region
+ that is about to be updated, and ensures that the associated
+ clients have updated their memory buffer. Then the server calls
+ the exposeRegion() function that composes the window surfaces and
+ copies the content of memory to screen by calling the blit() and
+ solidFill() functions.
+
+ The blit() function copies a given region in a given image to a
+ specified point using device coordinates, while the solidFill()
+ function fills the given region of the screen with the specified
+ color. Note that normally there is no need to call either of these
+ functions explicitly.
+
+ In addition, QScreen provides the blank() function that can be
+ reimplemented to prevent any contents from being displayed on the
+ screen, and the setDirty() function that can be reimplemented to
+ indicate that a given rectangle of the screen has been
+ altered. Note that the default implementations of these functions
+ do nothing.
+
+ Reimplement the the mapFromDevice() and mapToDevice() functions to
+ map objects from the framebuffer coordinate system to the
+ coordinate space used by the application, and vice versa. Be aware
+ that the default implementations simply return the given objects
+ as they are.
+
+ \section1 Properties
+
+ \table
+ \header \o Property \o Functions
+ \row
+ \o Size
+ \o
+
+ The size of the screen can be retrieved using the screenSize()
+ function. The size is returned in bytes.
+
+ The framebuffer's logical width and height can be retrieved using
+ width() and height(), respectively. These functions return values
+ are given in pixels. Alternatively, the physicalWidth() and
+ physicalHeight() function returns the same metrics in
+ millimeters. QScreen also provides the deviceWidth() and
+ deviceHeight() functions returning the physical width and height
+ of the device in pixels. Note that the latter metrics can differ
+ from the ones used if the display is centered within the
+ framebuffer.
+
+ \row
+ \o Resolution
+ \o
+
+ Reimplement the setMode() function to be able to set the
+ framebuffer to a new resolution (width and height) and bit depth.
+
+ The current depth of the framebuffer can be always be retrieved
+ using the depth() function. Use the pixmapDepth() function to
+ obtain the preferred depth for pixmaps.
+
+ \row
+ \o Pixmap Alignment
+ \o
+
+ Use the pixmapOffsetAlignment() function to retrieve the value to
+ which the start address of pixmaps held in the graphics card's
+ memory, should be aligned.
+
+ Use the pixmapLinestepAlignment() to retrieve the value to which
+ the \e {individual scanlines} of pixmaps should be aligned.
+
+ \row
+ \o Image Display
+ \o
+
+ The isInterlaced() function tells whether the screen is displaying
+ images progressively, and the isTransformed() function whether it
+ is rotated. The transformOrientation() function can be
+ reimplemented to return the current rotation.
+
+ \row
+ \o Scanlines
+ \o
+
+ Use the linestep() function to retrieve the length of each
+ scanline of the framebuffer.
+
+ \row
+ \o Pixel Type
+ \o
+
+ The pixelType() function returns the screen's pixel storage format as
+ described by the PixelType enum.
+
+ \endtable
+
+ \section1 Subclassing and Initial Values
+
+ You need to set the following members when implementing a subclass of QScreen:
+
+ \table
+ \header \o Member \o Initial Value
+ \row \o \l{QScreen::}{data} \o A pointer to the framebuffer if possible;
+ 0 otherwise.
+ \row \o \l{QScreen::}{lstep} \o The number of bytes between each scanline
+ in the framebuffer.
+ \row \o \l{QScreen::}{w} \o The logical screen width in pixels.
+ \row \o \l{QScreen::}{h} \o The logical screen height in pixels.
+ \row \o \l{QScreen::}{dw} \o The real screen width in pixels.
+ \row \o \l{QScreen::}{dh} \o The real screen height in pixels.
+ \row \o \l{QScreen::}{d} \o The number of bits per pixel.
+ \row \o \l{QScreen::}{physWidth} \o The screen width in millimeters.
+ \row \o \l{QScreen::}{physHeight} \o The screen height in millimeters.
+ \endtable
+
+ The logical screen values are the same as the real screen values unless the
+ screen is transformed in some way; e.g., rotated.
+
+ See also the \l{Accelerated Graphics Driver Example} for an example that
+ shows how to initialize these values.

+ \class QLinuxFbScreen
+ \ingroup qws
+
+ \brief The QLinuxFbScreen class implements a screen driver for the
+ Linux framebuffer.
+
+ Note that this class is only available in \l{Qt for Embedded Linux}.
+ Custom screen drivers can be added by subclassing the
+ QScreenDriverPlugin class, using the QScreenDriverFactory class to
+ dynamically load the driver into the application, but there should
+ only be one screen object per application.
+
+ The QLinuxFbScreen class provides the cache() function allocating
+ off-screen graphics memory, and the complementary uncache()
+ function releasing the allocated memory. The latter function will
+ first sync the graphics card to ensure the memory isn't still
+ being used by a command in the graphics card FIFO queue. The
+ deleteEntry() function deletes the given memory block without such
+ synchronization. Given the screen instance and client id, the
+ memory can also be released using the clearCache() function, but
+ this should only be necessary if a client exits abnormally.
+
+ In addition, when in paletted graphics modes, the set() function
+ provides the possibility of setting a specified color index to a
+ given RGB value.
+
+ The QLinuxFbScreen class also acts as a factory for the
+ unaccelerated screen cursor and the unaccelerated raster-based
+ implementation of QPaintEngine (\c QRasterPaintEngine);
+ accelerated drivers for Linux should derive from this class.

+ Custom screen drivers can be added by subclassing the
+ QScreenDriverPlugin class, using the QScreenDriverFactory class to
+ dynamically load the driver into the application, but there should
+ only be one screen object per application.
+
+ Use the QScreen::isTransformed() function to determine if a screen
+ is transformed. The QTransformedScreen class itself provides means
+ of rotating the screen with its setTransformation() function; the
+ transformation() function returns the currently set rotation in
+ terms of the \l Transformation enum (which describes the various
+ available rotation settings). Alternatively, QTransformedScreen
+ provides an implementation of the QScreen::transformOrientation()
+ function, returning the current rotation as an integer value.

+ Custom screen drivers can be added by subclassing the

+ only be one screen object per application.
+
+ The Qt for Embedded Linux platform provides a \l{The Virtual

+ the virtual framebuffer allows Qt for Embedded Linux applications to be
+ developed on a desktop machine, without switching between consoles

+ \class QTransportAuth
+ \internal
+
+ \brief Authenticate a message transport.
+
+ For performance reasons, message authentication is tied to an individual
+ message transport instance. For example in connection oriented transports
+ the authentication cookie can be cached against the connection avoiding
+ the overhead of authentication on every message.
+
+ For each process there is one instance of the QTransportAuth object.
+ For server processes it can determine the \link secure-exe-environ.html SXE
+ Program Identity \endlink and provide access to policy data to determine if
+ the message should be forwarded for action. If not actioned, the message
+ may be treated as being from a flawed or malicious process.
+
+ Retrieve the instance with the getInstance() method. The constructor is
+ disabled and instances of QTransportAuth should never be constructed by
+ calling classes.
+
+ To make the Authentication easier to use a proxied QIODevice is provided
+ which uses an internal QBuffer.
+
+ In the server code first get a pointer to a QTransportAuth::Data object
+ using the connectTransport() method:
+
+ \snippet doc/src/snippets/code/src_gui_embedded_qtransportauth_qws.cpp 0
+
+ Here it is asserted that the transport is trusted. See the assumptions
+ listed in the \link secure-exe-environ.html SXE documentation \endlink
+
+ Then proxy in the authentication device:
+
+ \snippet doc/src/snippets/code/src_gui_embedded_qtransportauth_qws.cpp 1
+
+ In the client code it is similar. Use the connectTransport() method
+ just the same then proxy in the authentication device instead of the
+ socket in write calls:
+
+ \snippet doc/src/snippets/code/src_gui_embedded_qtransportauth_qws.cpp 2

+
+ \l QUnixSocket allows you to transfer Unix file descriptors between processes.
+ A file descriptor is referred to as "rights data" as it allows one process to
+ transfer its right to access a resource to another.
+
+ The Unix system verifies resource permissions only when the resource is first
+ opened. For example, consider a file on disk readable only by the user "qt".
+ A process running as user "qt" will be able to open this file for reading.
+ If, while the process was still reading from the file, the ownership was
+ changed from user "qt" to user "root", the process would be allowed to
+ continue reading from the file, even though attempting to reopen the file
+ would be denied. Permissions are associated with special descriptors called
+ file descriptors which are returned to a process after it initially opens a
+ resource.
+
+ File descriptors can be duplicated within a process through the dup(2) system
+ call. File descriptors can be passed between processes using the
+ \l QUnixSocket class in the same way. Even though the receiving process never
+ opened the resource directly, it has the same permissions to access it as the
+ process that did.

+
+ In addition to transmitting regular byte stream data, messages sent over Unix
+ domain sockets may have special ancillary properties. QUnixSocketMessage
+ instances allow programmers to retrieve and control these properties.
+
+ Every QUnixSocketMessage sent has an associated set of credentials. A
+ message's credentials consist of the process id, the user id and the group id
+ of the sending process. Normally these credentials are set automatically for
+ you by the QUnixSocketMessage class and can be queried by the receiving
+ process using the \l QUnixSocketMessage::processId(),
+ \l QUnixSocketMessage::userId() and \l QUnixSocketMessage::groupId() methods
+ respectively.
+
+ Advanced applications may wish to change the credentials that their message
+ is sent with, and may do so though the \l QUnixSocketMessage::setProcessId(),
+ \l QUnixSocketMessage::setUserId() and \l QUnixSocketMessage::setGroupId()
+ methods. The validity of these credentials is verified by the system kernel.
+ Only the root user can send messages with credentials that are not his own.
+ Sending of the message will fail for any non-root user who attempts to
+ fabricate credentials. Note that this failure is enforced by the system
+ kernel - receivers can trust the accuracy of credential data!
+
+ Unix domain socket messages may also be used to transmit Unix file descriptors
+ between processes. In this context, file descriptors are known as rights data
+ and are encapsulated by the \l QUnixSocketRights class. Senders can set the
+ file descriptors to transmit using the \l QUnixSocketMessage::setRights() and
+ receivers can retrieve this data through a call to
+ \l QUnixSocketMessage::rights(). \l QUnixSocket and \l QUnixSocketRights
+ discuss the specific copy and ordering semantic associated with rights data.
+
+ QUnixSocketMessage messages are sent by the \l QUnixSocket::write() method.
+ Like any normal network message, attempting to transmit an empty
+ QUnixSocketMessage will succeed, but result in a no-op. Limitations in the
+ Unix domain protocol semantic will cause a transmission of a
+ QUnixSocketMessage with rights data, but no byte data portion, to fail.

+
+ \brief The QUnixSocket class provides a Unix domain socket.
+
+ \omit
+ \ingroup Platform::DeviceSpecific
+ \ingroup Platform::OS
+ \ingroup Platform::Communications
+ \endomit
+ \ingroup qws
+
+ Unix domain sockets provide an efficient mechanism for communications between
+ Unix processes on the same machine. Unix domain sockets support a reliable,
+ stream-oriented, connection-oriented transport protocol, much like TCP
+ sockets. Unlike IP based sockets, the connection endpoint of a Unix domain
+ socket is a file on disk of type socket.
+
+ In addition to transporting raw data bytes, Unix domain sockets are able to
+ transmit special ancillary data. The two types of ancillary data supported
+ by the QUnixSocket class are:
+
+ \list
+ \o Credential Data - Allows a receiver
+ to reliably identify the process sending each message.
+ \o \l {QUnixSocketRights}{Rights Data } - Allows Unix file descriptors
+ to be transmitted between processes.
+ \endlist
+
+ Because of the need to support ancillary data, QUnixSocket is not a QIODevice,
+ like QTcpSocket and QUdpSocket. Instead, QUnixSocket contains a number of
+ read and write methods that clients must invoke directly. Rather than
+ returning raw data bytes, \l QUnixSocket::read() returns \l QUnixSocketMessage
+ instances that encapsulate the message's byte data and any other ancillary
+ data.
+
+ Ancillary data is transmitted "out of band". Every \l QUnixSocketMessage
+ received will have credential data associated with it that the client can
+ access through calls to \l QUnixSocketMessage::processId(),
+ \l QUnixSocketMessage::groupId() and \l QUnixSocketMessage::userId().
+ Likewise, message creators can set the credential data to send through calls
+ to \l QUnixSocketMessage::setProcessId(), \l QUnixSocketMessage::setGroupId()
+ and \l QUnixSocketMessage::setUserId() respectively. The authenticity of the
+ credential values is verified by the system kernel and cannot be fabricated
+ by unprivileged processes. Only processes running as the root user can
+ specify credential data that does not match the sending process.
+
+ Unix file descriptors, known as "rights data", transmitted between processes
+ appear as though they had been dup(2)'d between the two. As Unix
+ domain sockets present a continuous stream of bytes to the receiver, the
+ rights data - which is transmitted out of band - must be "slotted" in at some
+ point. The rights data is logically associated with the first byte - called
+ the anchor byte - of the \l QUnixSocketMessage to which they are attached.
+ Received rights data will be available from the
+ \l QUnixSocketMessage::rights() method for the \l QUnixSocketMessage
+ instance that contains the anchor byte.
+
+ In addition to a \l QUnixSocket::write() that takes a \l QUnixSocketMessage
+ instance - allowing a client to transmit both byte and rights data - a
+ number of convenience overloads are provided for use when only transmitting
+ simple byte data. Unix requires that at least one byte of raw data be
+ transmitted in order to send rights data. A \l QUnixSocketMessage instance
+ with rights data, but no byte data, cannot be transmitted.
+
+ Unix sockets present a stream interface, such that, for example, a single
+ six byte transmission might be received as two three byte messages. Rights
+ data, on the other hand, is conceptually transmitted as unfragmentable
+ datagrams. If the receiving buffer is not large enough to contain all the
+ transmitted rights information, the data is truncated and irretreivably lost.
+ Users should use the \l QUnixSocket::setRightsBufferSize() method to control
+ the buffer size used for this data, and develop protocols that avoid the
+ problem. If the buffer size is too small and rights data is truncated,
+ the \l QUnixSocketMessage::rightsWereTruncated() flag will be set.

+
+ \brief The QUnixSocketServer class provides a Unix domain socket based server.
+ \omit
+ \ingroup Platform::DeviceSpecific
+ \ingroup Platform::OS
+ \ingroup Platform::Communications
+ \endomit
+ \ingroup qws
+
+ This class makes it possible to accept incoming Unix domain socket
+ connections. Call \l QUnixSocketServer::listen() to have the server listen
+ for incoming connections on a specified path. The pure virtual
+ \l QUnixSocketServer::incomingConnection() is called each time a new
+ connection is established. Users must inherit from QUnixSocketServer and
+ implement this method.
+
+ If an error occurs, \l QUnixSocketServer::serverError() returns the type of
+ error. Errors can only occur during server establishment - that is, during a
+ call to \l QUnixSocketServer::listen(). Calling \l QUnixSocketServer::close()
+ causes QUnixSocketServer to stop listening for connections and reset its
+ state.
+
+ QUnixSocketServer is often used in conjunction with the \l QUnixSocket class.
+
+ \sa QUnixSocket

+/*!
+ \enum QUnixSocketServer::ServerError
+
+ The ServerError enumeration represents the errors that can occur during server
+ establishment. The most recent error can be retrieved through a call to
+ \l QUnixSocketServer::serverError().
+
+ \value NoError No error has occurred.
+ \value InvalidPath An invalid path endpoint was passed to
+ \l QUnixSocketServer::listen(). As defined by unix(7), invalid paths
+ include an empty path, or what more than 107 characters long.
+ \value ResourceError An error acquiring or manipulating the system's socket
+ resources occurred. For example, if the process runs out of available
+ socket descriptors, a ResourceError will occur.
+ \value BindError The server was unable to bind to the specified path.
+ \value ListenError The server was unable to listen on the specified path for
+ incoming connections.

+
+ When running \l{Qt for Embedded Linux} applications, it is the server
+ application that installs and controls the screensaver.
+ \l{Qt for Embedded Linux} supports multilevel screen saving; i.e., it is possible to
+ specify several different levels of screen responsiveness. For
+ example, you can choose to first turn off the light before you
+ fully activate the screensaver.
+
+ Note that there exists no default screensaver implementation.
+
+ To create a custom screensaver, derive from this class and
+ reimplement the restore() and save() functions. These functions
+ are called whenever the screensaver is activated or deactivated,
+ respectively. Once an instance of your custom screensaver is
+ created, you can use the QWSServer::setScreenSaver() function to

+ \class QWSWindow

+
+ \brief The QWSWindow class encapsulates a top-level window in
+ Qt for Embedded Linux.
+
+ When you run a \l{Qt for Embedded Linux} application, it either runs as a
+ server or connects to an existing server. As applications add and
+ remove windows, the server process maintains information about
+ each window. In \l{Qt for Embedded Linux}, top-level windows are
+ encapsulated as QWSWindow objects. Note that you should never
+ construct the QWSWindow class yourself; the current top-level
+ windows can be retrieved using the QWSServer::clientWindows()
+ function.
+
+ With a window at hand, you can retrieve its caption, name, opacity
+ and ID using the caption(), name(), opacity() and winId()
+ functions, respectively. Use the client() function to retrieve a
+ pointer to the client that owns the window.
+
+ Use the isVisible() function to find out if the window is
+ visible. You can find out if the window is completely obscured by
+ another window or by the bounds of the screen, using the
+ isFullyObscured() function. The isOpaque() function returns true
+ if the window has an alpha channel equal to 255. Finally, the
+ requestedRegion() function returns the region of the display the
+ window wants to draw on.

+ processes have different responsibilities: The client process
+ performs all application specific operations. The server process
+ is responsible for managing the clients as well as taking care of
+ the pointer handling, character input, and screen output. In
+ addition, the server provides functionality to handle input

+ the current windows can be retrieved using the
+ QWSServer::clientWindows() function, and each window can tell
+ which client that owns it through its QWSWindow::client()
+ function.
+
+ A QWSClient object has an unique ID that can be retrieved using
+ its clientId() function. QWSClient also provides the identity()
+ function which typically returns the name of this client's running

+
+/*!
+ \class QWSServer
+ \brief The QWSServer class encapsulates a server process in Qt for Embedded Linux.
+
+ \ingroup qws
+
+ When you run a \l{Qt for Embedded Linux} application, it either runs as a
+ server or connects to an existing server. The server and client
+ processes have different responsibilities: The client process
+ performs all application specific operations. The server process
+ is responsible for managing the clients as well as taking care of
+ the pointer handling, character input, and screen output. In
+ addition, the server provides functionality to handle input
+ methods.
+
+ In \l{Qt for Embedded Linux}, all system generated events are passed to the
+ server application which then propagates the event to the
+ appropriate client. See the \l{Qt for Embedded Linux Architecture}
+ documentation for details.
+
+ Note that this class is instantiated by QApplication for
+ \l{Qt for Embedded Linux} server processes; you should never construct this
+ class yourself. Use the instance() function to retrieve a pointer
+ to the server object.
+
+ Note that the static functions of the QWSServer class can only be
+ used in the server process.
+
+ \tableofcontents
+
+ \section1 Client Administration
+
+ As applications add and remove windows, the server process
+ maintains information about each window. In \l{Qt for Embedded Linux},
+ top-level windows are encapsulated as QWSWindow objects. Each
+ window can tell which client that owns it through its
+ QWSWindow::client() function. Use the clientWindows() function to
+ retrieve a list of the current top-level windows. Given a
+ particular position on the display, the window containing it can
+ be retrieved using the windowAt() function.
+
+ QWSServer also provides the windowEvent() signal which is emitted
+ whenever something happens to a top level window; the WindowEvent
+ enum describes the various types of events that the signal
+ recognizes. In addition, the server class provides the
+ markedText() signal which is emitted whenever some text has been
+ selected in any of the windows, passing the selection as
+ parameter.
+
+ The QCopChannel class and the QCOP communication protocol enable
+ transfer of messages between clients. QWSServer provides the
+ newChannel() and removedChannel() signals that is emitted whenever
+ a new QCopChannel object is created or destroyed, respectively.
+
+ See also: QWSWindow, QWSClient and QCopChannel.
+
+
+ \section1 Mouse Handling
+
+ The mouse driver (represented by an instance of the
+ QWSMouseHandler class) is loaded by the server application when it
+ starts running, using Qt's \l {How to Create Qt Plugins}{plugin
+ system}. A mouse driver receives mouse events from the device and
+ encapsulates each event with an instance of the QWSEvent class
+ which it then passes to the server.
+
+ The openMouse() function opens the mouse devices specified by the
+ QWS_MOUSE_PROTO environment variable, and the setMouseHandler()
+ functions sets the primary mouse driver. Alternatively, the static
+ setDefaultMouse() function provides means of specifying the mouse
+ driver to use if the QWS_MOUSE_PROTO variable is not defined (note
+ that the default is otherwise platform dependent). The primary
+ mouse driver can be retrieved using the static mouseHandler()
+ function. Use the closeMouse() function to delete the mouse
+ drivers.
+
+ In addition, the QWSServer class can control the flow of mouse
+ input using the suspendMouse() and resumeMouse() functions.
+
+ See also: QWSMouseHandler and \l{Qt for Embedded Linux Pointer Handling}.
+
+ \section1 Keyboard Handling
+
+ The keyboard driver (represented by an instance of the
+ QWSKeyboardHandler class) is loaded by the server application when
+ it starts running, using Qt's \l {How to Create Qt Plugins}{plugin
+ system}. A keyboard driver receives keyboard events from the
+ device and encapsulates each event with an instance of the
+ QWSEvent class which it then passes to the server.
+
+ The openKeyboard() function opens the keyboard devices specified
+ by the QWS_KEYBOARD environment variable, and the
+ setKeyboardHandler() functions sets the primary keyboard
+ driver. Alternatively, the static setDefaultKeyboard() function
+ provides means of specifying the keyboard driver to use if the
+ QWS_KEYBOARD variable is not defined (note again that the default
+ is otherwise platform dependent). The primary keyboard driver can
+ be retrieved using the static keyboardHandler() function. Use the
+ closeKeyboard() function to delete the keyboard drivers.
+
+ In addition, the QWSServer class can handle key events from both
+ physical and virtual keyboards using the processKeyEvent() and
+ sendKeyEvent() functions, respectively. Use the
+ addKeyboardFilter() function to filter the key events from
+ physical keyboard drivers, the most recently added filter can be
+ removed and deleted using the removeKeyboardFilter() function.
+
+ See also: QWSKeyboardHandler and \l{Qt for Embedded Linux Character Input}.
+
+ \section1 Display Handling
+
+ When a screen update is required, the server runs through all the
+ top-level windows that intersect with the region that is about to
+ be updated, and ensures that the associated clients have updated
+ their memory buffer. Then the server uses the screen driver
+ (represented by an instance of the QScreen class) to copy the
+ content of the memory to the screen.
+
+ In addition, the QWSServer class provides some means of managing
+ the screen output: Use the refresh() function to refresh the
+ entire display, or alternatively a specified region of it. The
+ enablePainting() function can be used to disable (and enable)
+ painting onto the screen. QWSServer also provide the
+ setMaxWindowRect() function restricting the area of the screen
+ which \l{Qt for Embedded Linux} applications will consider to be the
+ maximum area to use for windows. To set the brush used as the
+ background in the absence of obscuring windows, QWSServer provides
+ the static setBackground() function. The corresponding
+ backgroundBrush() function returns the currently set brush.
+
+ QWSServer also controls the screen saver: Use the setScreenSaver()
+ to install a custom screen saver derived from the QWSScreenSaver
+ class. Once installed, the screensaver can be activated using the
+ screenSaverActivate() function, and the screenSaverActive()
+ function returns its current status. Use the
+ setScreenSaverInterval() function to specify the timeout interval.
+ \l{Qt for Embedded Linux} also supports multilevel screen saving, use the
+ setScreenSaverIntervals() function to specify the various levels
+ and their timeout intervals.
+
+ Finally, the QWSServer class controls the cursor's appearance,
+ i.e., use the setCursorVisible() function to hide or show the
+ cursor, and the isCursorVisible() function to determine whether
+ the cursor is visible on the display or not.
+
+ See also: QScreen and \l{Qt for Embedded Linux Display Management}.
+
+ \section1 Input Method Handling
+
+ Whenever the server receives an event, it queries its stack of
+ top-level windows to find the window containing the event's
+ position (each window can identify the client application that
+ created it). Then the server forwards the event to the appropriate
+ client. If an input method is installed, it is used as a filter
+ between the server and the client application.
+
+ Derive from the QWSInputMethod class to create custom input
+ methods, and use the server's setCurrentInputMethod() function to
+ install it. Use the sendIMEvent() and sendIMQuery() functions to
+ send input method events and queries.
+
+ QWSServer provides the IMMouse enum describing the various mouse
+ events recognized by the QWSInputMethod::mouseHandler()
+ function. The latter function allows subclasses of QWSInputMethod
+ to handle mouse events within the preedit text.

+ \class QWSInputMethod
+ \preliminary
+ \ingroup qws
+
+ \brief The QWSInputMethod class provides international input methods
+ in Qt for Embedded Linux.
+
+ Note that this class is only available in \l{Qt for Embedded Linux}.
+
+ A \l{Qt for Embedded Linux} application requires a server application to be
+ running, or to be the server application itself. All system
+ generated events, including keyboard and mouse events, are passed
+ to the server application which then propagates the event to the
+ appropriate client.
+
+ An input method consists of a filter and optionally a graphical
+ interface, and is used to filter input events between the server
+ and the client application.
+
+ \tableofcontents
+
+ \section1 Creating Custom Input Methods
+
+ To implement a custom input method, derive from the QWSInputMethod
+ class, and use the server's \l
+ {QWSServer::}{setCurrentInputMethod()} function to install it.
+
+ When subclassing QWSInputMethod, you can reimplement the filter()
+ functions to handle input from both physical and virtual keyboards
+ as well as mouse devices. Note that the default implementations do
+ nothing. Use the setInputResolution() function to control the
+ number of bits shifted when filtering mouse input, i.e., when
+ going from pointer resolution to screen resolution (the current
+ resolution can be retrieved using the inputResolutionShift()
+ function).
+
+ Reimplement the reset() function to restore the state of the input
+ method. Note that the default implementation calls the sendEvent()
+ function with empty preedit and commit strings if the input method
+ is in compose mode (i.e., if the input method is actively
+ composing a preedit string).
+
+ To receive replies to an input method query (sent using the
+ sendQuery() function), you must reimplement the queryResponse()
+ function, while the mouseHandler() function must be reimplemented
+ if you want to handle mouse events within the preedit
+ text. Reimplement the updateHandler() function to handle update
+ events including resets and focus changes. The UpdateType enum
+ describes the various types of update events recognized by the
+ input method.
+
+ \section1 Using Input Methods
+
+ In addition to the filter(), reset(), queryResponse(),
+ mouseHandler() and updateHandler() function mentioned in the
+ previous section, the QWSInputMethod provides several other
+ functions helping the window system to manage the installed input
+ methods.
+
+ The sendEvent() function sends the given event to the focus
+ widget, while the sendPreeditString() function sends the given
+ preedit text (encapsulated by an event). QWSInputMethod also
+ provides the sendCommitString() convenience function which sends
+ an event encapsulating the given commit string to the current
+ focus widget, and the sendMouseEvent() function which sends the
+ given mouse event.
+
+ Finally, the QWSInputMethod class provides the sendQuery()
+ function for sending input method queries. This function
+ encapsulates the event with a QWSEvent instance of the \l
+ {QWSEvent::}{IMQuery} type.

+ \ingroup qws
+
+ \brief The KeyboardFilter class is a base class for global
+ keyboard event filters in Qt for Embedded Linux.
+
+ Note that this class is only available in \l{Qt for Embedded Linux}.
+
+ In \l{Qt for Embedded Linux}, all system generated events, including
+ keyboard events, are passed to the server application which then
+ propagates the event to the appropriate client. The KeyboardFilter
+ class is used to implement a global, low-level filter on the
+ server side. The server applies the filter to all keyboard events
+ before passing them on to the clients:
+
+ \image qwsserver_keyboardfilter.png
+
+ This feature can, for example, be used to filter things like APM
+ (advanced power management) suspended from a button without having
+ to filter for it in all applications.
+
+ To add a new keyboard filter you must first create the filter by
+ deriving from this class, reimplementing the pure virtual filter()
+ function. Then you can install the filter on the server using
+ QWSServer's \l {QWSServer::}{addKeyboardFilter()}
+ function. QWSServer also provides a \l
+ {QWSServer::}{removeKeyboardFilter()} function.
+
+ \sa {Qt for Embedded Linux Architecture}, QWSServer, QWSInputMethod
+*/
+
+/*!
+ \fn QWSServer::KeyboardFilter::~KeyboardFilter()
+
+ Destroys the keyboard filter.
+*/
+
+/*!
+ \fn bool QWSServer::KeyboardFilter::filter(int unicode, int keycode, int modifiers, bool isPress, bool autoRepeat)
+
+ Implement this function to return true if a given key event should
+ be stopped from being processed any further; otherwise it should
+ return false.
+
+ A key event can be identified by the given \a unicode value and
+ the \a keycode, \a modifiers, \a isPress and \a autoRepeat
+ parameters.
+
+ The \a keycode parameter is the Qt keycode value as defined by the
+ Qt::Key enum. The \a modifiers is an OR combination of
+ Qt::KeyboardModifier values, indicating whether \gui
+ Shift/Alt/Ctrl keys are pressed. The \a isPress parameter is true
+ if the event is a key press event and \a autoRepeat is true if the
+ event is caused by an auto-repeat mechanism and not an actual key
+ press.

+ in Qt for Embedded Linux.
+
+ Note that this class is only available in \l{Qt for Embedded Linux}.
+
+ QWSEmbedWidget inherits QWidget and acts as any other widget, but
+ in addition it is capable of embedding another top-level widget.
+
+ An example of use is when painting directly onto the screen using
+ the QDirectPainter class. Then the reserved region can be embedded
+ into an instance of the QWSEmbedWidget class, providing for
+ example event handling and size policies for the reserved region.
+
+ All that is required to embed a top-level widget is its window ID.
+
+ \sa {Qt for Embedded Linux Architecture}

+/*!
+ \class QWSEvent
+ \ingroup qws
+
+ \brief The QWSEvent class encapsulates an event in Qt for Embedded Linux.
+
+ When running a \l{Qt for Embedded Linux} application, it either runs as a
+ server or connects to an existing server. All system generated
+ events are passed to the server application which then propagates
+ the event to the appropriate client.
+
+ Whenever the server receives an event, it queries its stack of
+ top-level windows to find the window containing the event's
+ position. Each window can identify the client application that
+ created it, and returns its ID to the server upon
+ request. Finally, the server forwards the event, encapsulated by
+ an instance of the QWSEvent class, to the appropriate client.
+
+ \image qt-embedded-client.png
+
+ The server communicates with the client applications over the UNIX
+ domain socket. You can retrieve direct access to all the events a
+ client receives from the server, by reimplementing QApplication's
+ \l {QApplication::}{qwsEventFilter()} function.
+
+ QWSEvent provides the \l Type enum specifying the origin of the
+ event. Internally, each type is represented by a QWSEvent
+ subclass, e.g., \c QWSKeyEvent.
+
+ \sa QWSServer, QWSClient, {Qt for Embedded Linux Architecture}
+*/
+
+/*!
+ \enum QWSEvent::Type
+
+ This enum describes the origin of the event.
+
+ \value NoEvent No event has occurred.
+ \value Connected An application has connected to the server.
+ \value Mouse A mouse button is pressed or released, or the mouse cursor is moved.
+ See also \l{Qt for Embedded Linux Pointer Handling}.
+ \value Focus A window has lost or received focus.
+ \value Key A key is pressed or released. See also \l{Qt for Embedded Linux Character Input}.
+ \value Region A region has changed.
+ \value Creation The server has created an ID, typically for a window.
+ \value PropertyNotify A property has changed.
+ \value PropertyReply The server is responding to a request for a property's value.
+ \value SelectionClear A selection is deleted.
+ \value SelectionRequest The server has queried for a selection.
+ \value SelectionNotify A new selection has been created.
+ \value MaxWindowRect The server has changed the maximum window for an application.
+ \value QCopMessage A new Qt Cop message has appeared. See also QCopChannel
+ \value WindowOperation A window operation, e.g. resizing, has occurred.
+ \value IMEvent An input method has been used to enter text for languages with
+ non-Latin alphabets. See also QWSInputMethod.
+ \value IMQuery An input method query for a specified property has occurred.
+ See also QWSInputMethod.
+ \value NEvent The number of events has changed.
+ \value Embed An event used internally to implement embedded windows. See also
+ QWSEmbedWidget.
+ \value ScreenTransformation An event used internally to notify the client processes
+ that the screen has changed for example, rotation, etc.
