Function documentation

Bool_t MouseEnter(TGLOvlSelectRecord& selRec)

 Mouse has enetered this element.
 Return TRUE if you want additional events.

Bool_t MouseStillInside(TGLOvlSelectRecord& selRec)

 A new overlay hit is about to be processed.
 By returning FALSE one can force mouse-leave (MouseLeave will be
 called shortly).
 If you return TRUE, Handle will be called soon.
 Use this if your overlay object has some inactive parts,
 see TGLManipSet.

Bool_t Handle(TGLRnrCtx& rnrCtx, TGLOvlSelectRecord& selRec, Event_t* event)

 Handle overlay event.
 Return TRUE if event was handled.

void MouseLeave()

 Mouse has left the element.

TGLOverlayElement& operator=(const TGLOverlayElement& )

virtual ~TGLOverlayElement()

{}

void Render(TGLRnrCtx& rnrCtx)
