Bool_t IsGrabSelected(UInt_t selectEventMask)
 return the selection by "grabButton" / "grabPointer"
void AddKeyEvent(const int& event, TQtClientWidget* widget)
 Map and and to the ROOT event queue Qt KeyBoard event mapped to the ROOT Event_t
 For "dest" widget
bool SelectGrab(Event_t& event, UInt_t selectEventMask, int& me)
 Select Event:  --  04.12.2005  --
bool eventFilter(QObject* o, QEvent* e)
 Dispatch The Qt event from event queue to Event_t structure
 Not all of the event fields are valid for each event type,
 except fType and fWindow.
void GrabPointer(TQtClientWidget* grabber, UInt_t evmask, Window_t confine, QCursor* cursor, Bool_t grab = kTRUE, Bool_t owner_events = kTRUE)
 Set the X11 style active grabbing for ROOT TG widgets
