|
|
|
|
|
|
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>.

|
|
<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.
