#include <rendereventhandler.h>
A render event handler object is notified by the RenderDevice about noteworthy events.
To react to those events, derive a class from RenderEventHandler, and attach to the render device via RenderDevice::AttachEventHandler().
Inherits Core::RefCounted.
Inherited by CoreGraphics::ThreadSafeRenderEventHandler.

called when an event should be processed, override this method in your subclass
Handle a render event.
This method is usually called by PutEvent(), but subclasses of RenderEventHandler may choose to implement a different behaviour. Override this method in your subclass to process the incoming event.
Reimplemented in CoreGraphics::ThreadSafeRenderEventHandler.

called by RenderDevice when an event happens
This method is called by the RenderDevice when an event happens.
The default behaviour of this class is to call the HandleEvent() method directly. Subclasses of RenderEventHandler may choose to implement a different behaviour.
Reimplemented in CoreGraphics::ThreadSafeRenderEventHandler.
