# qgfxdriverplugin(3qt)

Abstract base for Qt/Embedded graphics driver plugins

## NAME

QGfxDriverPlugin - Abstract base for Qt/Embedded graphics driver plugins

## SYNOPSIS

`#include <qgfxdriverplugin_qws.h>`

### Public Members

**QGfxDriverPlugin ()**\
 **~QGfxDriverPlugin ()**\
 **virtual QStringList keys () const = 0**\
 **virtual QScreen \* create ( const QString & driver, int displayId ) = 0**\

## 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().
