Public Member Functions
virtual bool	initialize (const SDuckcppCreationParameters &params, const SExposedVideoData &data)=0
	Initialize manager with device creation parameters and device window (passed as exposed video data)
virtual void	terminate ()=0
	Terminate manager, any cleanup that is left over. Manager needs a new initialize to be usable again.
virtual bool	generateSurface ()=0
	Create surface based on current window set.
virtual void	destroySurface ()=0
	Destroy current surface.
virtual bool	generateContext ()=0
	Create context based on current surface.
virtual void	destroyContext ()=0
	Destroy current context.
virtual const SExposedVideoData &	getContext () const =0
	Get current context.
virtual bool	activateContext (const SExposedVideoData &videoData, bool restorePrimaryOnZero=false)=0
	Change render context, disable old and activate new defined by videoData.
virtual bool	swapBuffers ()=0
	Swap buffers.

Member Function Documentation

activateContext()

virtual bool dcpp::video::IContextManager::activateContext ( const SExposedVideoData &  videoData, bool  restorePrimaryOnZero = false  )

pure virtual

Change render context, disable old and activate new defined by videoData.

This is mostly used internally by IVideoDriver::beginScene(). But if you want to switch threads which access your OpenGL driver you will have to call this function as follows: Old thread gives up context with: activateContext(dcpp::video::SExposedVideoData()); New thread takes over context with: activateContext(videoDriver->getExposedVideoData()); Note that only 1 thread at a time may access an OpenGL context.
