The handler <em>may</em> be passed to the system for later destruction with <a href="qwsserver.html#setKeyboardHandler">QWSServer::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="~QWSKeyboardHandler"></a>QWSKeyboardHandler::~QWSKeyboardHandler ()<tt> [virtual]</tt> </h3> Destroys a keyboard handler. Note that if you have called <a href="qwsserver.html#setKeyboardHandler">QWSServer::setKeyboardHandler</a>(), you must not delete the handler. <h3 class=fn>void <a name="processKeyEvent"></a>QWSKeyboardHandler::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. <p> <center><table cellpadding="4" cellspacing="2" border="0"> <tr bgcolor="#a2c511"> <th valign="top">Parameter <th valign="top">Meaning <tr bgcolor="#f0f0f0"> <td valign="top"><em>unicode</em> <td valign="top">The Unicode value for the key, or 0xFFFF is none is appropriate. <tr bgcolor="#d0d0d0"> <td valign="top"><em>keycode</em> <td valign="top">The Qt keycode for the key (see <a href="qt.html#Key-enum">Qt::Key</a> for the list of codes). <tr bgcolor="#f0f0f0"> <td valign="top"><em>modifiers</em> <td valign="top">The set of modifier keys (see <a href="qt.html#Modifier-enum">Qt::Modifier</a>). <tr bgcolor="#d0d0d0"> <td valign="top"><em>isPress</em> <td valign="top">Whether this is a press or a release. <tr bgcolor="#f0f0f0"> <td valign="top"><em>autoRepeat</em> <td valign="top">Whether this event was generated by an auto-repeat mechanism, or an actual key press. </table></center> <!-- eof --> <hr><p> This file is part of the <a href="index.html">Qt toolkit</a>.
