<hr><a name="details"></a><h2>Detailed Description</h2>
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::Lower</tt> - The window has been lowered.
<li><tt>TQWSServer::Geometry</tt> - The window has changed size or position.
<li><tt>TQWSServer::Active</tt> - The window has become the active window (has <a href="focus.html#keyboard-focus">keyboard focus</a>).

"virtual keyboards". <em>unicode</em> is the Unicode value of the key to
send, <em>keycode</em> the TQt keycode (e.g. <tt>Key_Left</tt>), <em>modifiers</em>
indicates whether, Shift/Alt/Ctrl keys are pressed, <em>isPress</em> is
TRUE if this is a key down event and FALSE if it's a key up event,

</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.
