Class Description

______________________________________________________________________________________
Bool_t IsGrabSelected(UInt_t selectEventMask)
 return the selection by "grabButton" / "grabPointer"
~TQtClientFilter()


void AddKeyEvent( const QKeyEvent &keyEvent, TQtClientWidget *frame)


 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,QMouseEvent &mouse)


 Select Event:  --  04.12.2005  --



bool eventFilter( QObject *qWidget, 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.
