Class Description

~TQtClientFilter()

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.

void GrabPointer(TQtClientWidget *grabber, UInt_t evmask, Window_t /*confine*/, QCursor *cursor, Bool_t grab, Bool_t owner_events)

 Set the X11 style active grabbing for ROOT TG widgets
