Key events may come from several different -sources. -<p> <h2> Keyboard drivers -</h2> -<a name="1"></a><p> A keyboard driver reads data from a device and gives key events to the -server. -<p> Keyboard drivers can be compiled into the library or loaded as -plugins. Running ./configure -help lists the available keyboard drivers. -The "tty" driver is enabled in the default configuration. -<p> The keyboard drivers all follow the same pattern. They read keyboard -data from a device, find out which keys were pressed, and then call -the static function TQWSServer::processKeyEvent() with the key information. -<p> At present, the console keyboard driver also handles console switching -(<b>Ctrl+Alt-F1</b>...<b>Ctrl+Alt+F10</b>) and termination -(<b>Ctrl+Alt+Backspace</b>). -<p> To add a keyboard driver for a new device, subclasses of -<a href="qwskeyboardhandler.html">TQWSKeyboardHandler</a> and <a href="qkbddriverplugin.html">TQKbdDriverPlugin</a> can be -written and installed as plugins. -<p> <h2> Key event filters (input methods) -</h2> -<a name="2"></a><p> When the server receives a key event from a keyboard driver, it first -passes it through a filter. -<p> This can be used to implement input methods, providing input of -characters that are not on the keyboard. -<p> To make an input method, subclass TQWSServer::KeyboardFilter (in <tt>src/kernel/qwindowsystem_qws.h</tt>) and implement the virtual function <tt>filter()</tt>. If <tt>filter()</tt> returns <tt>FALSE</tt>, the event will be sent to -the clients (using <a href="qwsserver.html#sendKeyEvent">TQWSServer::sendKeyEvent</a>()). If <tt>filter()</tt> returns -<tt>TRUE</tt>, the event will be stopped. To generate new key events, use -TQWSServer::sendKeyEvent(). (Do not use processKeyEvent(), since this -will lead to infinite recursion.) -<p> To install a keyboard event filter, use -<a href="qwsserver.html#setKeyboardFilter">TQWSServer::setKeyboardFilter</a>(). Currently, only one filter -can be installed at a time. -<p> Filtering must be done in the server process. -<p> The launcher example contains an example of a simple input method, -<tt>SimpleIM</tt> which reads a substitution table from a file. -<p> <h2> Pen input -</h2> -<a name="3"></a><p> Key events do not need to come from a keyboard device. The server -process may call TQWSServer::sendKeyEvent() at any time. -<p> Typically, this is done by popping up a widget, and letting the user -specify characters with the pointer device. -<p> <b>Note</b>: the key input widget should not take focus, since the -server would then just send the key events back to the input widget. -One way to make sure that the input widget never takes focus is to set -the <tt>WStyle_Customize</tt> and <tt>WStyle_Tool</tt> widget flags in -the <a href="tqwidget.html">TQWidget</a> constructor. -<p> The <a href="http://www.trolltech.com/products/qtopia/">TQtopia</a> -environment contains various input widgets such as -Handwriting Recognition and Virtual Keyboard. -<p> -<!-- eof --> -<p><address><hr><div align=center> -<table width=100% cellspacing=0 border=0><tr> -<td>Copyright © 2007 -<a href="troll.html">Trolltech</a><td align=center><a href="trademarks.html">Trademarks</a> -<td align=right><div align=right>TQt 3.3.8</div> -</table></div></address></body> -</html> |
