The TQGfxDriverPlugin class provides an abstract base for
TQt/Embedded graphics driver plugins.
<p> 
<p> The graphics driver plugin is a simple plugin interface that makes
it easy to create custom graphics drivers.
<p> Writing a graphics driver plugin is achieved by subclassing this
base class, reimplementing the pure virtual functions <a href="#keys">keys</a>() and
<a href="#create">create</a>(), and exporting the class with the <tt>TQ_EXPORT_PLUGIN</tt>
macro. See the <a href="plugins-howto.html">Plugins
    documentation</a> for details.
<p> This class is only available in TQt/Embedded.
<p>See also <a href="plugins.html">Plugins</a>.

<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQGfxDriverPlugin"></a>TQGfxDriverPlugin::TQGfxDriverPlugin ()
</h3>
Constructs a graphics driver plugin. This is invoked automatically
by the <tt>TQ_EXPORT_PLUGIN</tt> macro.

<h3 class=fn><a name="~TQGfxDriverPlugin"></a>TQGfxDriverPlugin::~TQGfxDriverPlugin ()
</h3>
Destroys the graphics driver 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="qscreen.html">TQScreen</a>&nbsp;* <a name="create"></a>TQGfxDriverPlugin::create ( const&nbsp;<a href="ntqstring.html">TQString</a>&nbsp;&amp;&nbsp;driver, int&nbsp;displayId )<tt> [pure virtual]</tt>
</h3>

<p> Creates a driver matching the type specified by <em>driver</em>, that
will use display <em>displayId</em>.
<p> <p>See also <a href="#keys">keys</a>().

<h3 class=fn><a href="ntqstringlist.html">TQStringList</a> <a name="keys"></a>TQGfxDriverPlugin::keys () const<tt> [pure virtual]</tt>
</h3>

<p> Returns the list of graphics drivers this plugin supports.
<p> <p>See also <a href="#create">create</a>().
