IAcPiPropertyEditEventsSink

The IAcPiPropertyEditControlEventSink interface is implemented by property edit controls, with the Property Inspector as its listener. Property edit controls are not aware of other controls; to help the Property Inspector coordinate its handling of all controls, editor controls should use this sink to notify the Property Inspector when they receive user events. For instance, to facilitate tab stop handling, a control can use the OnKeyDown() notification to tell the Property Inspector that it has been clicked.
