Detailed Description

Plasma Applet that is fully rendered using OpengGL.

Definition at line 37 of file glapplet.h.

Constructor & Destructor Documentation

Plasma::GLApplet::GLApplet	(	QGraphicsItem *	parent,
		const QString &	serviceId,
		int	appletId
	)

Parameters

parent	the QGraphicsItem this applet is parented to
serviceId	the name of the .desktop file containing the information about the widget
appletId	a unique id used to differentiate between multiple instances of the same Applet type

Definition at line 67 of file glapplet.cpp.

Plasma::GLApplet::GLApplet	(	QObject *	parent,
		const QVariantList &	args
	)

This constructor is to be used with the plugin loading systems found in KPluginInfo and KService.

The argument list is expected to have two elements: the KService service ID for the desktop entry and an applet ID which must be a base 10 number.

Parameters

parent	a QObject parent; you probably want to pass in 0
args	a list of strings containing two entries: the service id and the applet id

void Plasma::GLApplet::paintGLInterface ( QPainter *  painter, const QStyleOptionGraphicsItem *  option  )

virtual

Reimplement this method to render using OpenGL.

QPainter passed to this method will always use OpenGL engine and rendering using OpenGL api directly is supported.
