Detailed Description
The QWSKeyboardHandler class implements the keyboard driver/handler for Qt/Embedded.
The keyboard handler (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.
Member Function Documentation
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 may 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.
- unicode is the Unicode value for the key, or 0xFFFF is none is appropriate.
- keycode is the Qt keycode for the key (see Qt::Key). for the list of codes).
- modifiers is the set of modifier keys (see Qt::Modifier).
- isPress says whether this is a press or a release.
- autoRepeat says whether this event was generated by an auto-repeat mechanism, or an actual key press.
