Detailed Description

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 TQ_EXPORT_PLUGIN macro. See the Plugins documentation for details.

This class is only available in TQt/Embedded.

See also Plugins.

Member Function Documentation

TQGfxDriverPlugin::TQGfxDriverPlugin ()

TQGfxDriverPlugin::~TQGfxDriverPlugin ()

TQScreen * TQGfxDriverPlugin::create ( const TQString & driver, int displayId ) [pure virtual]

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

See also keys().

Returns the list of graphics drivers this plugin supports.
