Implicitly flushes the rendering pipeline and executes all received rendering commands before posting.

Implemented in kanzi::GlGraphicsOutput, and kanzi::NullGraphicsOutput.

unsigned int kanzi::GraphicsOutput::getWidth ( ) const

inline

Returns the width of rendering area in pixels.

unsigned int kanzi::GraphicsOutput::getHeight ( ) const

inline

Returns the height of rendering area in pixels.

enum KzsDisplayOrientationAngle kanzi::GraphicsOutput::getOrientationAngle ( ) const

inline

Returns the orientations of the rendering area.

void kanzi::GraphicsOutput::resize	(	unsigned int	width,
		unsigned int	height
	)

Resizes the rendering area.

virtual void kanzi::GraphicsOutput::handleEvents ( const struct KzsEventQueue *  eventQueue )

pure virtual

Handles appropriate events.

Implemented in kanzi::GlGraphicsOutput, and kanzi::NullGraphicsOutput.

virtual void kanzi::GraphicsOutput::resizeOverride ( unsigned int  width, unsigned int  height  )

inlineprotectedvirtual

Override function for resize().

Reimplemented in kanzi::GlGraphicsOutput.

void kanzi::GraphicsOutput::updateSize ( unsigned int  width, unsigned int  height  )

inlineprotected

Updates the rendering area size.
