<h2>Detailed Description</h2>
<p>The QGenericPlugin class is an abstract base class for window-system related plugins in Qt QPA.</p>
<p>Note that this class is only available in Qt QPA.</p>
<p>A mouse plugin can be created by subclassing QGenericPlugin and reimplementing the pure virtual <a href="qgenericplugin.html#keys">keys</a>() and <a href="qgenericplugin.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="qgenericpluginfactory.html">QGenericPluginFactory</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>

<h3 class="fn"><a name="QGenericPlugin"></a>QGenericPlugin::<span class="name">QGenericPlugin</span> ( <span class="type"><a href="qobject.html">QObject</a></span> * <i>parent</i> = 0 )</h3>
<p>Constructs a 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>

<!-- $$$~QGenericPlugin[overload1]$$$~QGenericPlugin -->
<h3 class="fn"><a name="dtor.QGenericPlugin"></a>QGenericPlugin::<span class="name">~QGenericPlugin</span> ()</h3>
<p>Destroys the 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>
<!-- @@@~QGenericPlugin -->

<p>Implement this function to create a driver matching the type specified by the given <i>key</i> and <i>specification</i> parameters. Note that keys are case-insensitive.</p>
