DESCRIPTION
       The QWSServer class provides server-specific functionality in
       Qt/Embedded.

       When you run a Qt/Embedded application, it either runs as a server or
       connects to an existing server. If it runs as a server, some additional
       operations are provided by this class.

       This class is instantiated by QApplication for Qt/Embedded server
       processes. You should never construct this class yourself.

       A pointer to the QWSServer instance can be obtained via the global
       qwsServer variable.

       The mouse and keyboard devices can be opened with openMouse() and
       openKeyboard(). (Close them with closeMouse() and closeKeyboard().)

       The display is refreshed with refresh(), and painting can be enabled or
       disabled with enablePainting().

       Obtain the list of client windows with clientWindows() and find out
       which window is at a particular point with windowAt().

       Many static functions are provided, for example, setKeyboardFilter(),
       setKeyboardHandler(), setDefaultKeyboard() and setDefaultMouse().

       The size of the window rectangle can be set with setMaxWindowRect(),
       and the desktop's background can be set with setDesktopBackground().

       The screen saver is controlled with setScreenSaverInterval() and
       screenSaverActivate().

       See also Qt/Embedded.

   Member Type Documentation
QWSServer::GUIMode
       This determines what sort of QWS server to create:

       QWSServer::NoGui - This is used for non-graphical Qt applications.

       QWSServer::NormalGUI - A normal Qt/Embedded application (not the
       server).

       QWSServer::Server - A Qt/Embedded server (e.g. if -qws has been
       specified on the command line.

QWSServer::ServerFlags
       This enum is used to pass various options to the window system server.

       QWSServer::DisableKeyboard - Ignore all keyboard input.

       QWSServer::DisableMouse - Ignore all mouse input.

QWSServer::WindowEvent
       This specifies what sort of event has occurred to a top-level window:

       QWSServer::Create - A new window has been created (QWidget
       constructor).

       QWSServer::Destroy - The window has been closed and deleted (QWidget
       destructor).

       QWSServer::Hide - The window has been hidden with QWidget::hide().

       QWSServer::Show - The window has been shown with QWidget::show() or
       similar.

       QWSServer::Raise - The window has been raised to the top of the
       desktop.

       QWSServer::Lower - The window has been lowered.

       QWSServer::Geometry - The window has changed size or position.

       QWSServer::Active - The window has become the active window (has
       keyboard focus).

       QWSServer::Name - The window has been named.

MEMBER FUNCTION DOCUMENTATION
QWSServer::QWSServer ( int flags = 0, QObject * parent = 0, const char * name
       = 0 )
       Construct a QWSServer object.

       Warning: This class is instantiated by QApplication for Qt/Embedded
       server processes. You should never construct this class yourself.

       The flags are used for keyboard and mouse setting. The server's parent
       is parent and it is called name.

QWSServer::~QWSServer ()
       Destruct QWSServer

const QPtrList<;QWSWindow> & QWSServer::clientWindows ()
       Returns the list of top-level windows. This list will change as
       applications add and remove wigdets so it should not be stored for
       future use. The windows are sorted in stacking order from top-most to
       bottom-most.

void QWSServer::closeKeyboard ()
       Closes keyboard device(s).

void QWSServer::closeMouse ()
       Closes the pointer device(s).

void QWSServer::enablePainting ( bool e )
       If e is TRUE, painting on the display is enabled; if e is FALSE,
       painting is disabled.

bool QWSServer::isCursorVisible () [static]
       Returns TRUE if the cursor is visible; otherwise returns FALSE.

       See also setCursorVisible().

const KeyMap * QWSServer::keyMap () [static]
       Returns the keyboard mapping table used to convert keyboard scancodes
       to Qt keycodes and Unicode values. It's used by the keyboard driver in
       qkeyboard_qws.cpp.

QWSKeyboardHandler * QWSServer::keyboardHandler () [static]
       Returns the primary keyboard handler.

QWSPropertyManager * QWSServer::manager ()
       Returns the QWSPropertyManager, which is used for implementing
       X11-style window properties.

QWSMouseHandler * QWSServer::mouseHandler () [static]
       Returns the primary mouse handler.

void QWSServer::newChannel ( const QString & channel ) [signal]
       This signal is emitted when the QCopChannel channel is created.

void QWSServer::openKeyboard ()
       Opens the keyboard device(s).

void QWSServer::openMouse ()
       Opens the mouse device(s).

void QWSServer::refresh ()
       Refreshes the entire display.

void QWSServer::refresh ( QRegion & r )
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       Refreshes the region r.

void QWSServer::removedChannel ( const QString & channel ) [signal]
       This signal is emitted immediately after the QCopChannel channel is
       destroyed. Note that a channel is not destroyed until all its listeners
       have unregistered.

void QWSServer::screenSaverActivate ( bool activate ) [static]
       If activate is TRUE the screensaver is activated immediately; if
       activate is FALSE the screensaver is deactivated.

bool QWSServer::screenSaverActive () [static]
       Returns TRUE if the screensaver is active (i.e. the screen is blanked);
       otherwise returns FALSE.

void QWSServer::sendIMEvent ( IMState state, const QString & txt, int cpos,
       int selLen )
       This function sends an input method event to the server. The current
       state is passed in state and the current text in txt. The cursor's
       position in the text is given by cpos, and the selection length (which
       could be 0) is given in selLen.

void QWSServer::sendKeyEvent ( int unicode, int keycode, int modifiers, bool
       isPress, bool autoRepeat ) [static]
       Send a key event. You can use this to send key events generated by"
       virtual keyboards". unicode is the Unicode value of the key to send,
       keycode the Qt keycode (e.g. Key_Left), modifiers indicates whether,
       Shift/Alt/Ctrl keys are pressed, isPress is TRUE if this is a key down
       event and FALSE if it's a key up event, and autoRepeat is TRUE if this
       is an autorepeat event (i.e. the user has held the key down and this is
       the second or subsequent key event being sent).

void QWSServer::setCursorVisible ( bool vis ) [static]
       If vis is TRUE, makes the cursor visible; if vis is FALSE, makes the
       cursor invisible.

       See also isCursorVisible().

void QWSServer::setDefaultKeyboard ( const char * k ) [static]
       Set the keyboard driver to k, e.g. if $QWS_KEYBOARD is not defined. The
       default is platform-dependent.

void QWSServer::setDefaultMouse ( const char * m ) [static]
       Set the mouse driver m to use if $QWS_MOUSE_PROTO is not defined. The
       default is platform-dependent.

void QWSServer::setDesktopBackground ( const QImage & img ) [static]
       Sets the image img to be used as the background in the absence of
       obscuring windows.

void QWSServer::setDesktopBackground ( const QColor & c ) [static]
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       Sets the color c to be used as the background in the absence of
       obscuring windows.

void QWSServer::setKeyboardFilter ( KeyboardFilter * f ) [static]
       Adds a filter f to be invoked for all key events from physical keyboard
       drivers (events sent via processKeyEvent()).

       The filter is not invoked for keys generated by virtual keyboard
       drivers (events sent via sendKeyEvent()).

       If f is 0, the most-recently added filter is removed and deleted. The
       caller is responsible for matching each addition with a corresponding
       removal.

void QWSServer::setKeyboardHandler ( QWSKeyboardHandler * kh ) [static]
       Sets the primary keyboard handler to kh.

void QWSServer::setMaxWindowRect ( const QRect & r ) [static]
       Sets the area of the screen which Qt/Embedded applications will
       consider to be the maximum area to use for windows to r.

       See also QWidget::showMaximized().

void QWSServer::setScreenSaverInterval ( int ms ) [static]
       Sets the timeout for the screensaver to ms milliseconds. A setting of
       zero turns off the screensaver.

void QWSServer::setScreenSaverIntervals ( int * ms ) [static]
       Sets an array of timeouts for the screensaver to a list of ms
       milliseconds. A setting of zero turns off the screensaver. The array
       must be 0-terminated.

QWSWindow * QWSServer::windowAt ( const QPoint & pos )
       Returns the window containing the point pos or 0 if there is no window
       under the point.

void QWSServer::windowEvent ( QWSWindow * w, QWSServer::WindowEvent e )
       [signal]
       This signal is emitted whenever something happens to a top-level window
       (e.g. it's created or destroyed). w is the window to which the event of
       type e has occurred.
