## Detailed Description

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 via the QWSServer 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.

## Member Type Documentation

### QWSServer::WindowEvent

This enum type defines the Qt/Embedded window system events:

- `Create` - a new window has been created.
- `Destroy` - a window has been destroyed.
- `Hide` - a window has been hidden.
- `Show` - a window has been shown.
- `Raise` - a window has been raised.
- `Lower` - a window has been lowered.
- `Geometry` - the size and/or position of a window has changed.
- `Active` - a window has become the active window (has keyboard focus).

## Member Function Documentation

### QWSServer::QWSServer ( int flags = 0, QObject * parent=0, const char * name=0 )

Construct a QWSServer class.

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

### QWSServer::~QWSServer ()

Destruct QWSServer.

### const QList<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 lowest.

### void QWSServer::closeKeyboard ()

Closes keyboard device(s).

### void QWSServer::closeMouse ()

Closes pointer device(s).

### void QWSServer::enablePainting ( bool e )

Disables all painting on the display.

### bool QWSServer::isCursorVisible () `[static]`

Returns TRUE is the cursor is visible, or FALSE if it is hidden.

See also setCursorVisible().

### QWSKeyboardHandler* QWSServer::keyboardHandler () `[static]`

Returns the primary keyboard handler.

### QWSMouseHandler * QWSServer::mouseHandler () `[static]`

Returns the primary mouse handler.

### void QWSServer::newChannel ( const QString & channel ) `[signal]`

This signal is emitted when QCopChannel channel is created.

### void QWSServer::openKeyboard ()

Open keyboard device(s).

### void QWSServer::openMouse ()

Opens the mouse device(s).

### void QWSServer::refresh ()

Refreshes the entire display.

### 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 listeners have unregistered.

### void QWSServer::screenSaverActivate ( bool activate ) `[static]`

Activates the screensaver immediately if `activate` is TRUE otherwise deactivates the screensaver.

### bool QWSServer::screenSaverActive () `[static]`

Returns TRUE if the screensaver is active (i.e. blanked).

### 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".

### void QWSServer::sendMouseEvent ( const QPoint & pos, int state ) `[static]`

Send a mouse event.

### void QWSServer::setCursorVisible ( bool visible ) `[static]`

Shows the cursor if visible is TRUE, otherwise hides the cursor.

See also isCursorVisible().

### void QWSServer::setDefaultKeyboard ( const char * k ) `[static]`

Set the keyboard driver to use if $QWS_KEYBOARD is not defined. The default is platform-dependant.

### void QWSServer::setDefaultMouse ( const char * m ) `[static]`

Set the mouse driver to use if $QWS_MOUSE_PROTO is not defined. The default is platform-dependant.

### void QWSServer::setDesktopBackground ( const QColor & c ) `[static]`

Sets the color to use as the background in the absence of obscuring windows.

### void QWSServer::setDesktopBackground ( const QImage & img ) `[static]`

Sets the image to use as the background in the absence of obscuring windows.

### void QWSServer::setKeyboardFilter ( KeyboardFilter * f ) `[static]`

Adds a filter 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 send 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 application will consider to be the maximum area to use for windows.

See also QWidget::showMaximized().

### void QWSServer::setOverrideKeys ( QIntDict<QWSServer::KeyMap> * map ) `[static]`

Changes the mapping of the keyboard; adding the scancode to Unicode mappings from map. The server takes over ownership of map and will delete it. Use QCollection::setAutoDelete() to control whether the contents of map should be deleted.

Passing a null pointer for map will revert to the default keymap.

### 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 * window, QWSServer::WindowEvent event ) `[signal]`

This signal is emitted when a window system event event has been processed for window.

### void QWSServer::beginDisplayReconfigure () `[static]`

For internal use only.

### void QWSServer::closedown () `[static]`

For internal use only.

### void QWSServer::endDisplayReconfigure () `[static]`

For internal use only.

### void QWSServer::processEventQueue () `[static]`

For internal use only.

### void QWSServer::processKeyEvent ( int unicode, int keycode, int modifiers, bool isPress, bool autoRepeat ) `[static]`

For internal use only.

### void QWSServer::sendPropertyNotifyEvent ( int property, int state )

For internal use only.

### void QWSServer::setMouseHandler ( QWSMouseHandler * mh ) `[static]`

For internal use only.

### void QWSServer::startup ( int flags ) `[static]`

For internal use only.

### QList<QWSInternalWindowInfo> * QWSServer::windowList () `[static]`

For internal use only.
