virtual void BALL::VIEW::GLRenderWindow::refresh

(

)

[virtual]

Request that the image is actually displayed on the screen or other device the window encapsulated.

You should implement this method in subclass. This is different from RenderTarget releaseBuffer. ReleaseBuffer only informs the window that a buffer is ready, but does not imply the buffer is actually displayed somewhere. This is done by refresh. On the other hand, refresh called inbetween getBuffer and releaseBuffer has no effect.

Reimplemented from BALL::VIEW::RenderWindow< float >.

virtual bool BALL::VIEW::GLRenderWindow::resize	(	const unsigned int	width,
		const unsigned int	height
	)			[virtual]

Request new window size.

Returns false if such a size cannot be supplied This call must be made before the window buffer is handed out to be rendered. This precondition is being checked automatically, see getBuffer
