.SH DESCRIPTION
The QGfxDriverPlugin class provides an abstract base for Qt/Embedded graphics driver plugins.
.PP
The graphics driver plugin is a simple plugin interface that makes it easy to create custom graphics drivers.
.PP
Writing a graphics driver plugin is achieved by subclassing this base class, reimplementing the pure virtual functions keys() and create(), and exporting the class with the \fCQ_EXPORT_PLUGIN\fR macro. See the Plugins documentation for details.
.PP
This class is only available in Qt/Embedded.
.PP
See also Plugins.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QGfxDriverPlugin::QGfxDriverPlugin ()"
Constructs a graphics driver plugin. This is invoked automatically by the \fCQ_EXPORT_PLUGIN\fR macro.
.SH "QGfxDriverPlugin::~QGfxDriverPlugin ()"
Destroys the graphics driver plugin.
.PP
You never have to call this explicitly. Qt destroys a plugin automatically when it is no longer used.
.SH "QScreen * QGfxDriverPlugin::create ( const QString & driver, int displayId )\fC [pure virtual]\fR"
Creates a driver matching the type specified by \fIdriver\fR, that will use display \fIdisplayId\fR.
.PP
See also keys().
.SH "QStringList QGfxDriverPlugin::keys () const\fC [pure virtual]\fR"
Returns the list of graphics drivers this plugin supports.
.PP
See also create().
