QScreenDriverPlugin Class Reference

Member Function Documentation

QScreenDriverPlugin::QScreenDriverPlugin ( QObject * parent = 0 )

Constructs a screen driver plugin with the given parent.

Note that this constructor is invoked automatically by the Q_EXPORT_PLUGIN2() macro, so there is no need for calling it explicitly.

QScreenDriverPlugin::~QScreenDriverPlugin ()

Destroys this screen driver plugin.

Note that Qt destroys a plugin automatically when it is no longer used, so there is no need for calling the destructor explicitly.

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

Implement this function to create a driver matching the type specified by the given key and displayId parameters. Note that keys are case-insensitive.

See also keys().

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

Implement this function to return the list of valid keys, i.e. the screen drivers supported by this plugin.

Qt for Embedded Linux provides ready-made drivers for several screen protocols, see the display management documentation for details.
