See the <a href="plugins-howto.html">plugins documentation</a> for an example. <p>See also <a href="plugins.html">Plugins</a>. <hr><h2>Member Function Documentation</h2> <h3 class=fn><a name="TQStylePlugin"></a>TQStylePlugin::TQStylePlugin () </h3> Constructs a style plugin. This is invoked automatically by the <tt>Q_EXPORT_PLUGIN</tt> macro. <h3 class=fn><a name="~TQStylePlugin"></a>TQStylePlugin::~TQStylePlugin () </h3> Destroys the style plugin. <p> You never have to call this explicitly. TQt destroys a plugin automatically when it is no longer used. <h3 class=fn><a href="ntqstyle.html">TQStyle</a> * <a name="create"></a>TQStylePlugin::create ( const <a href="ntqstring.html">TQString</a> & key )<tt> [pure virtual]</tt> </h3> <p> Creates and returns a <a href="ntqstyle.html">TQStyle</a> object for the style key <em>key</em>. The style key is usually the class name of the required style. <p> <p>See also <a href="#keys">keys</a>(). <h3 class=fn><a href="ntqstringlist.html">TQStringList</a> <a name="keys"></a>TQStylePlugin::keys () const<tt> [pure virtual]</tt> </h3> <p> Returns the list of style keys this plugin supports. <p> These keys are usually the class names of the custom styles that are implemented in the plugin. <p> <p>See also <a href="#create">create</a>(). <!-- eof --> <hr><p> This file is part of the <a href="index.html">TQt toolkit</a>.
