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 by this 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. +

The mouse and keyboard devices can be opened with openMouse() and +openKeyboard(). (Close them with closeMouse() and +closeKeyboard().) +

The display is refreshed with refresh(), and painting can be +enabled or disabled with enablePainting(). +

Obtain the list of client windows with clientWindows() and find +out which window is at a particular point with windowAt(). +

Many static functions are provided, for example, +setKeyboardFilter(), setKeyboardHandler(), setDefaultKeyboard() +and setDefaultMouse(). +

The size of the window rectangle can be set with +setMaxWindowRect(), and the desktop's background can be set with +setDesktopBackground(). +

The screen saver is controlled with setScreenSaverInterval() and +screenSaverActivate(). +

Member Type Documentation

+

QWSServer::GUIMode

+ +

This determines what sort of QWS server to create: +

+

QWSServer::ServerFlags

+ +

This enum is used to pass various options to the window system +server. +

+

QWSServer::WindowEvent

+ +

This specifies what sort of event has occurred to a top-level window: +

+

Member Function Documentation

+

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

+Construct a QWSServer object. +

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

The flags are used for keyboard and mouse setting. The server's +parent is parent and it is called name. + +

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 bottom-most. + +

void QWSServer::closeKeyboard () +

+Closes keyboard device(s). + +

void QWSServer::closeMouse () +

+Closes the pointer device(s). + +

void QWSServer::enablePainting ( bool e ) +

+If e is TRUE, painting on the display is enabled; if e is +FALSE, painting is disabled. + +

bool QWSServer::isCursorVisible () [static] +

+Returns TRUE if the cursor is visible; otherwise returns FALSE. +

See also setCursorVisible(). + +

const KeyMap * QWSServer::keyMap () [static] +

+ +

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::newChannel ( const QString & channel ) [signal] +

+ +

This signal is emitted when the QCopChannel channel is created. + +

void QWSServer::openKeyboard () +

+Opens the keyboard device(s). + +

void QWSServer::openMouse () +

+Opens the mouse device(s). + +

void QWSServer::refresh () +

+Refreshes the entire display. + +

void QWSServer::refresh ( QRegion & r ) +

+This is an overloaded member function, provided for convenience. It behaves essentially like the above function. +

Refreshes the region r. + +

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 its listeners have unregistered. + +

void QWSServer::screenSaverActivate ( bool activate ) [static] +

+If activate is TRUE the screensaver is activated immediately; +if activate is FALSE the screensaver is deactivated. + +

bool QWSServer::screenSaverActive () [static] +

+Returns TRUE if the screensaver is active (i.e. the screen is +blanked); otherwise returns FALSE. + +

void QWSServer::sendIMEvent ( IMState state, const QString & txt, int cpos, int selLen ) +

+This function sends an input method event to the server. The +current state is passed in state and the current text in txt. The cursor's position in the text is given by cpos, and +the selection length (which could be 0) is given in selLen. + +

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/Ctrl keys are pressed, isPress is +TRUE if this is a key down event and 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::setCursorVisible ( bool vis ) [static] +

+If vis is TRUE, makes the cursor visible; if vis is FALSE, +makes the cursor invisible. +

See also isCursorVisible(). + +

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

+Set the keyboard driver to k, e.g. if $QWS_KEYBOARD is not +defined. The default is platform-dependent. + +

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-dependent. + +

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

+Sets the image img to be used 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 be used as the background in the absence of +obscuring windows. + +

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

+Adds 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 sent 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 applications will +consider to be the maximum area to use for windows to r. +

See also QWidget::showMaximized(). + +

void QWSServer::setScreenSaverInterval ( int ms ) [static] +

+Sets the timeout for the screensaver to ms milliseconds. A +setting of zero turns off the screensaver. + +

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 * w, QWSServer::WindowEvent e ) [signal] +

+ +

This signal is emitted whenever something happens to a top-level +window (e.g. it's created or destroyed). w is the window to +which the event of type e has occurred. + + +
