<h2>Detailed Description</h2>
<p>The QKbdDriverPlugin class is an abstract base class for keyboard driver plugins in Qt for Embedded Linux.</p>
<p>Note that this class is only available in <a href="qt-embedded-linux.html">Qt for Embedded Linux</a>.</p>
<p><a href="qt-embedded-linux.html">Qt for Embedded Linux</a> provides ready-made drivers for several keyboard protocols, see the <a href="qt-embedded-charinput.html">character input</a> documentation for details. Custom keyboard drivers can be implemented by subclassing the <a href="qwskeyboardhandler.html">QWSKeyboardHandler</a> class and creating a keyboard driver plugin.</p>
<p>A keyboard driver plugin can be created by subclassing QKbdDriverPlugin and reimplementing the pure virtual <a href="qkbddriverplugin.html#keys">keys</a>() and <a href="qkbddriverplugin.html#create">create</a>() functions. By exporting the derived class using the <a href="qtplugin.html#Q_EXPORT_PLUGIN2">Q_EXPORT_PLUGIN2</a>() macro, the default implementation of the <a href="qkbddriverfactory.html">QKbdDriverFactory</a> class will automatically detect the plugin and load the driver into the server application at run-time. See <a href="plugins-howto.html">How to Create Qt Plugins</a> for details.</p>
<p>See also <a href="qkbddriverfactory.html">QKbdDriverFactory</a> and <a href="qwskeyboardhandler.html">QWSKeyboardHandler</a>.</p>

<h2>Member Function Documentation</h2>
<a name="//apple_ref/cpp/instm/QKbdDriverPlugin/QKbdDriverPlugin"></a>
<h3 class="fn"><a name="QKbdDriverPlugin"></a>QKbdDriverPlugin::QKbdDriverPlugin ( <a href="qobject.html">QObject</a> * <i>parent</i> = 0 )</h3>
<p>Constructs a keyboard driver plugin with the given <i>parent</i>.</p>
<p>Note that this constructor is invoked automatically by the <a href="qtplugin.html#Q_EXPORT_PLUGIN2">Q_EXPORT_PLUGIN2</a>() macro, so there is no need for calling it explicitly.</p>
<a name="//apple_ref/cpp/instm/QKbdDriverPlugin/~QKbdDriverPlugin"></a>
<h3 class="fn"><a name="dtor.QKbdDriverPlugin"></a>QKbdDriverPlugin::~QKbdDriverPlugin ()</h3>
<p>Destroys the keyboard driver plugin.</p>
<p>Note that Qt destroys a plugin automatically when it is no longer used, so there is no need for calling the destructor explicitly.</p>
<a name="//apple_ref/cpp/instm/QKbdDriverPlugin/create"></a>
<h3 class="fn"><a name="create"></a><a href="qwskeyboardhandler.html">QWSKeyboardHandler</a> * QKbdDriverPlugin::create ( const <a href="qstring.html">QString</a> & <i>key</i>, const <a href="qstring.html">QString</a> & <i>device</i> ) <tt> [pure virtual]</tt></h3>
<p>Implement this function to create a driver matching the type specified by the given <i>key</i> and <i>device</i> parameters. Note that keys are case-insensitive.</p>
<p>See also <a href="qkbddriverplugin.html#keys">keys</a>().</p>
<a name="//apple_ref/cpp/instm/QKbdDriverPlugin/keys"></a>
<h3 class="fn"><a name="keys"></a><a href="qstringlist.html">QStringList</a> QKbdDriverPlugin::keys () const <tt> [pure virtual]</tt></h3>
<p>Implement this function to return the list of valid keys, i.e. the keyboard drivers supported by this plugin.</p>
<p><a href="qt-embedded-linux.html">Qt for Embedded Linux</a> provides ready-made drivers for several keyboard protocols, see the <a href="qt-embedded-charinput.html">character input</a> documentation for details.</p>
