Jenya,
Look at vtkSMNewWidgetRepresentationProxy::ExecuteEvent. It fires
events when one interacts with the widget. You can add observers for
those events.
As far as documentation for such things goes, the source code if your
best guide -- attaching debugger and back tracking to determine why
that error is being thrown serves as a good starting point.
