|
|---|
| 90 | The QWSServer class provides server-specific functionality in Qt/Embedded.
|
|---|
| 91 | <p>
|
|---|
| 92 | <p> When you run a Qt/Embedded application, it either runs as a server
|
|---|
| 93 | or connects to an existing server. If it runs as a server, some
|
|---|
| 94 | additional operations are provided by this class.
|
|---|
| 95 | <p> This class is instantiated by <a href="qapplication.html">QApplication</a> for Qt/Embedded server
|
|---|
| 96 | processes. You should never construct this class yourself.
|
|---|
| 97 | <p> A pointer to the QWSServer instance can be obtained via the global
|
|---|
| 98 | <tt>qwsServer</tt> variable.
|
|---|
| 99 | <p> The mouse and keyboard devices can be opened with <a href="#openMouse">openMouse</a>() and
|
|---|
| 100 | <a href="#openKeyboard">openKeyboard</a>(). (Close them with <a href="#closeMouse">closeMouse</a>() and
|
|---|
| 101 | <a href="#closeKeyboard">closeKeyboard</a>().)
|
|---|
| 102 | <p> The display is refreshed with <a href="#refresh">refresh</a>(), and painting can be
|
|---|
| 103 | enabled or disabled with <a href="#enablePainting">enablePainting</a>().
|
|---|
| 104 | <p> Obtain the list of client windows with <a href="#clientWindows">clientWindows</a>() and find
|
|---|
| 105 | out which window is at a particular point with <a href="#windowAt">windowAt</a>().
|
|---|
| 106 | <p> Many static functions are provided, for example,
|
|---|
| 107 | <a href="#setKeyboardFilter">setKeyboardFilter</a>(), <a href="#setKeyboardHandler">setKeyboardHandler</a>(), <a href="#setDefaultKeyboard">setDefaultKeyboard</a>()
|
|---|
| 108 | and <a href="#setDefaultMouse">setDefaultMouse</a>().
|
|---|
| 109 | <p> The size of the window rectangle can be set with
|
|---|
| 110 | <a href="#setMaxWindowRect">setMaxWindowRect</a>(), and the desktop's background can be set with
|
|---|
| 111 | <a href="#setDesktopBackground">setDesktopBackground</a>().
|
|---|
| 112 | <p> The screen saver is controlled with <a href="#setScreenSaverInterval">setScreenSaverInterval</a>() and
|
|---|
| 113 | <a href="#screenSaverActivate">screenSaverActivate</a>().
|
|---|
| 114 | <p>See also <a href="qws.html">Qt/Embedded</a>.

| 122 | <li><tt>QWSServer::NormalGUI</tt> - A normal Qt/Embedded application (not the server).
|
|---|
| 123 | <li><tt>QWSServer::Server</tt> - A Qt/Embedded server (e.g. if <tt>-qws</tt> has been specified

| 134 | <h3 class=fn><a name="WindowEvent-enum"></a>QWSServer::WindowEvent</h3>
|
|---|
| 135 |
|

|
|---|
| 137 | <ul>
|
|---|
| 138 | <li><tt>QWSServer::Create</tt> - A new window has been created (<a href="qwidget.html">QWidget</a> constructor).
|
|---|
| 139 | <li><tt>QWSServer::Destroy</tt> - The window has been closed and deleted (QWidget destructor).
|
|---|
| 140 | <li><tt>QWSServer::Hide</tt> - The window has been hidden with <a href="qwidget.html#hide">QWidget::hide</a>().
|
|---|
| 141 | <li><tt>QWSServer::Show</tt> - The window has been shown with <a href="qwidget.html#show">QWidget::show</a>() or similar.
|
|---|
| 142 | <li><tt>QWSServer::Raise</tt> - The window has been raised to the top of the desktop.
|
|---|
| 143 | <li><tt>QWSServer::Lower</tt> - The window has been lowered.
|
|---|
| 144 | <li><tt>QWSServer::Geometry</tt> - The window has changed size or position.
|
|---|
| 145 | <li><tt>QWSServer::Active</tt> - The window has become the active window (has <a href="focus.html#keyboard-focus">keyboard focus</a>).
|
