.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.
|
||
|
|

|
||
|
|
