The TQWSKeyboardHandler class implements the keyboard driver
for TQt/Embedded.
< p >
< p > The keyboard driver handles events from system devices and
generates key events.
< p > A TQWSKeyboardHandler will usually open some system device in its
constructor, create a < a href = "ntqsocketnotifier.html" > TQSocketNotifier< / a > on that opened device and
when it receives data, it will call < a href = "#processKeyEvent" > processKeyEvent< / a > () to send the
event to TQt/Embedded for relaying to clients.
< p > See also < a href = "qws.html" > TQt/Embedded< / a > .
< hr > < h2 > Member Function Documentation< / h2 >
< h3 class = fn > < a name = "TQWSKeyboardHandler" > < / a > TQWSKeyboardHandler::TQWSKeyboardHandler ()
< / h3 >
Constructs a keyboard handler. The handler < em > may< / em > be passed to the
system for later destruction with < a href = "qwsserver.html#setKeyboardHandler" > TQWSServer::setKeyboardHandler< / a > (),
although even without doing this, the handler can function,
calling < a href = "#processKeyEvent" > processKeyEvent< / a > () to emit events.
< h3 class = fn > < a name = "~TQWSKeyboardHandler" > < / a > TQWSKeyboardHandler::~TQWSKeyboardHandler ()< tt > [virtual]< / tt >
< / h3 >
Destroys a keyboard handler. Note that if you have called
< a href = "qwsserver.html#setKeyboardHandler" > TQWSServer::setKeyboardHandler< / a > (), you must not delete the handler.
< h3 class = fn > void < a name = "processKeyEvent" > < / a > TQWSKeyboardHandler::processKeyEvent ( int unicode, int keycode, int modifiers, bool isPress, bool autoRepeat )< tt > [virtual protected]< / tt >
< / h3 >
Subclasses call this function to send a key event. The server may
additionally filter the event before sending it on to
applications.
