Detailed Description

The QGfxDriverPlugin class provides an abstract base for Qt/Embedded graphics driver plugins.

The graphics driver plugin is a simple plugin interface that makes it easy to create custom graphics drivers.

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 Q_EXPORT_PLUGIN macro. See the Plugins documentation for details.

This class is only available in Qt/Embedded.

See also Plugins.


Member Function Documentation

QGfxDriverPlugin::QGfxDriverPlugin ()

Constructs a graphics driver plugin. This is invoked automatically by the Q_EXPORT_PLUGIN macro.

QGfxDriverPlugin::~QGfxDriverPlugin ()

Destroys the graphics driver plugin.

You never have to call this explicitly. Qt destroys a plugin automatically when it is no longer used.

QScreen * QGfxDriverPlugin::create ( const QString & driver, int displayId ) [pure virtual]

Creates a driver matching the type specified by driver, that will use display displayId.

See also keys().

QStringList QGfxDriverPlugin::keys () const [pure virtual]

Returns the list of graphics drivers this plugin supports.

See also create().
