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 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

{ fButtonGrabList.append(widget);}
