The QWSKeyboardHandler class implements the keyboard driver for Qt/Embedded.

The keyboard driver handles events from system devices and generates key events.

A QWSKeyboardHandler will usually open some system device in its constructor, create a QSocketNotifier on that opened device and when it receives data, it will call processKeyEvent() to send the event to Qt/Embedded for relaying to clients.

See also Qt/Embedded.


QWSKeyboardHandler::QWSKeyboardHandler ()

Constructs a keyboard handler. The handler may be passed to the system for later destruction with QWSServer::setKeyboardHandler(), although even without doing this, the handler can function, calling processKeyEvent() to emit events.

QWSKeyboardHandler::~QWSKeyboardHandler () [virtual]

Destroys a keyboard handler. Note that if you have called QWSServer::setKeyboardHandler(), you must not delete the handler.

void QWSKeyboardHandler::processKeyEvent ( int unicode, int keycode, int modifiers, bool isPress, bool autoRepeat ) [virtual protected]

Subclasses call this function to send a key event. The server may additionally filter the event before sending it on to applications.
