.SH DESCRIPTION
The QWSKeyboardHandler class implements the keyboard driver for Qt/Embedded.
.PP
The keyboard driver handles events from system devices and generates key events.
.PP
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.
.PP
See also Qt/Embedded.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QWSKeyboardHandler::QWSKeyboardHandler ()"
Constructs a keyboard handler. The handler \fImay\fR 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.
.SH "QWSKeyboardHandler::~QWSKeyboardHandler ()\fC [virtual]\fR"
Destroys a keyboard handler. Note that if you have called QWSServer::setKeyboardHandler(), you must not delete the handler.
.SH "void QWSKeyboardHandler::processKeyEvent ( int unicode, int keycode, int modifiers, bool isPress, bool autoRepeat )\fC [virtual protected]\fR"
Subclasses call this function to send a key event. The server may additionally filter the event before sending it on to applications.
