Detailed 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 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.
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.
Currently defined are:
- 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
Member Function Documentation
QWSServer::QWSServer ( int flags = 0, QObject * parent = 0, const char * name = 0 )
Construct a QWSServer class with parent parent, called name
and flags flags.
This class is instantiated by QApplication for Qt/Embedded server processes.
You should never construct this class yourself.
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 lowest.
void QWSServer::closeKeyboard ()
Closes keyboard device(s).
void QWSServer::closeMouse ()
Closes pointer device(s).
void QWSServer::enablePainting ( bool e )
Enables (if e is true) or disables all painting on the display.
const KeyMap * QWSServer::keyMap () [static]
This 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::openKeyboard ()
Open keyboard device(s).
void QWSServer::openMouse ()
Opens the mouse device(s).
void QWSServer::refresh ()
Refreshes the entire display.
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". unicode is the unicode value of the key to
send, keycode the Qt keycode (e.g. Key_Left), modifiers
indicates whether, shift/alt/control keys are pressed, isPress
is true if this is a key down event, 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::sendMouseEvent ( const QPoint & pos, int state ) [static]
Send a mouse event. pos is the position on screen of the mouse
event, state is a mask indicating which buttons are pressed.
void QWSServer::setDefaultKeyboard ( const char * k ) [static]
Set the keyboard driver k to use if $QWS_KEYBOARD is not defined.
The default is platform-dependant.
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-dependant.
void QWSServer::setDesktopBackground ( const QImage & img ) [static]
Sets the image img to use 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 use as the background in the absence of obscuring
windows.
void QWSServer::setKeyboardFilter ( KeyboardFilter * f ) [static]
Sets 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 send via sendKeyEvent()).
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 r which Qt/Embedded applications will consider
to be the maximum area to use for windows.
See also QWidget::showMaximized().
void QWSServer::setScreenSaverInterval ( int ms ) [static]
Sets the timeout for the screensaver to ms milliseconds. A setting
of zero turns of the screensaver.
QWSWindow * QWSServer::windowAt ( const QPoint & pos )
Returns the window containing the point pos or 0 if there is no window
under the point.
This signal is triggered whenever something happens to a top level
window (e.g. it's created or destroyed). w is the window
to which an event has happened, e specifies what type of event
has occurred.
