class TGLEventHandler: public TGEventHandler


 Base-class and default implementation of event-handler for TGLViewer.

 This allows for complete disentanglement of GL-viewer from GUI
 event handling. Further, alternative event-handlers can easily be
 designed and set at run-time.

 The signals about object being selected or hovered above are
 emitted via the TGLViewer itself.

 This class is still under development.

Function documentation

TGLEventHandler(const char* name, TGWindow* w, TObject* obj, const char* title = "")
 Constructor.
~TGLEventHandler()
 Destructor.
void ExecuteEvent(Int_t event, Int_t px, Int_t py)
 Process event of type 'event' - one of EEventType types,
 occuring at window location px, py
 This is provided for use when embedding GL viewer into pad
Bool_t HandleEvent(Event_t* event)
 Handle generic Event_t type 'event' - provided to catch focus changes
 and terminate any interaction in viewer.
Bool_t HandleFocusChange(Event_t* event)
 Handle generic Event_t type 'event' - provided to catch focus changes
 and terminate any interaction in viewer.
Bool_t HandleCrossing(Event_t* event)
 Handle generic Event_t type 'event' - provided to catch focus changes
 and terminate any interaction in viewer.
Bool_t HandleButton(Event_t* event)
 Handle mouse button 'event'.
Bool_t HandleDoubleClick(Event_t* event)
 Handle mouse double click 'event'.
Bool_t HandleConfigureNotify(Event_t* event)
 Handle configure notify 'event' - a window resize/movement.
Bool_t HandleExpose(Event_t* event)
 Handle window expose 'event' - show.
Bool_t HandleKey(Event_t* event)
 Handle keyboard 'event'.
Bool_t HandleMotion(Event_t* event)
 Handle mouse motion 'event'.
Bool_t Rotate(Int_t xDelta, Int_t yDelta, Bool_t mod1, Bool_t mod2)
 Method to handle action TGLViewer::kDragCameraRotate.
Bool_t HandleTimer(TTimer* t)
 If mouse delay timer times out emit signal.
void StartMouseTimer()
 Start mouse timer in single-shot mode.
void StopMouseTimer()
 Make sure mouse timers are not running.
void ClearMouseOver()
 Clear mouse-over state and emit mouse-over signals.
 Current overlay element is also told the mouse has left.
void Repaint()
 Handle window expose 'event' - show.
void TriggerTooltip(const char* text)
 Trigger display of tooltip.
void RemoveTooltip()
 Hide the tooltip.
void SetMouseOverSelectDelay(Int_t ms)
 Set delay of mouse-over probe (highlight).
void SetMouseOverTooltipDelay(Int_t ms)
 Set delay of tooltip timer.
Int_t GetTooltipPixelTolerance() const
{ return fTooltipPixelTolerance; }
void SetTooltipPixelTolerance(Int_t t)
{ fTooltipPixelTolerance = t; }
