The TQWSServer class provides server-specific functionality in TQt/Embedded.
< p >
< p > When you run a TQt/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.
< p > This class is instantiated by < a href = "ntqapplication.html" > TQApplication< / a > for TQt/Embedded server
processes. You should never construct this class yourself.
< p > A pointer to the TQWSServer instance can be obtained via the global
< tt > qwsServer< / tt > variable.
< p > The mouse and keyboard devices can be opened with < a href = "#openMouse" > openMouse< / a > () and
< a href = "#openKeyboard" > openKeyboard< / a > (). (Close them with < a href = "#closeMouse" > closeMouse< / a > () and
< a href = "#closeKeyboard" > closeKeyboard< / a > ().)
< p > The display is refreshed with < a href = "#refresh" > refresh< / a > (), and painting can be
enabled or disabled with < a href = "#enablePainting" > enablePainting< / a > ().
< p > Obtain the list of client windows with < a href = "#clientWindows" > clientWindows< / a > () and find
out which window is at a particular point with < a href = "#windowAt" > windowAt< / a > ().
< p > Many static functions are provided, for example,
< a href = "#setKeyboardFilter" > setKeyboardFilter< / a > (), < a href = "#setKeyboardHandler" > setKeyboardHandler< / a > (), < a href = "#setDefaultKeyboard" > setDefaultKeyboard< / a > ()
and < a href = "#setDefaultMouse" > setDefaultMouse< / a > ().
< p > The size of the window rectangle can be set with
< a href = "#setMaxWindowRect" > setMaxWindowRect< / a > (), and the desktop's background can be set with
< a href = "#setDesktopBackground" > setDesktopBackground< / a > ().
< p > The screen saver is controlled with < a href = "#setScreenSaverInterval" > setScreenSaverInterval< / a > () and
< a href = "#screenSaverActivate" > screenSaverActivate< / a > ().
< p > See also < a href = "qws.html" > TQt/Embedded< / a > .

< li > < tt > TQWSServer::Destroy< / tt > - The window has been closed and deleted (TQWidget destructor).
< li > < tt > TQWSServer::Hide< / tt > - The window has been hidden with < a href = "ntqwidget.html#hide" > TQWidget::hide< / a > ().
< li > < tt > TQWSServer::Show< / tt > - The window has been shown with < a href = "ntqwidget.html#show" > TQWidget::show< / a > () or similar.
< li > < tt > TQWSServer::Raise< / tt > - The window has been raised to the top of the desktop.
< li > < tt > TQWSServer::Lower< / tt > - The window has been lowered.
< li > < tt > TQWSServer::Geometry< / tt > - The window has changed size or position.

keyboard drivers (events sent via processKeyEvent()).
< p > The filter is not invoked for keys generated by virtual keyboard
drivers (events sent via < a href = "#sendKeyEvent" > sendKeyEvent< / a > ()).
< p > If < em > f< / em > is 0, the most-recently added filter is removed and deleted.
The caller is responsible for matching each addition with a
corresponding removal.

< / h3 >
Sets an array of timeouts for the screensaver to a list of < em > ms< / em >
milliseconds. A setting of zero turns off the screensaver. The
array must be 0-terminated.

< / h3 >
Returns the window containing the point < em > pos< / em > or 0 if there is no
window under the point.
< h3 class = fn > void < a name = "windowEvent" > < / a > TQWSServer::windowEvent ( < a href = "qwswindow.html" > TQWSWindow< / a > * w, < a href = "qwsserver.html#WindowEvent-enum" > TQWSServer::WindowEvent< / a > e )< tt > [signal]< / tt >

window (e.g. it's created or destroyed). < em > w< / em > is the window to
which the event of type < em > e< / em > has occurred.
