Sorry if these seem like ridiculous questions guys, but I'm still
trying to figure out what is going on.

I invoked SelectionChanged from the OnLeftButtonUp override:

void vtkInteractorStyleRubberBand2D::OnLeftButtonUp()
{
  vtkstd::cout << "Left Button Up." << vtkstd::endl;
  InvokeEvent(vtkCommand::SelectionChangedEvent);
}

My SelectionChangedCallbackFunction then gets called (which it didn't
when I didn't invoke that event), but the rubberband still does not
disappear when I release the left mouse button. I tried invoking
EndPickEvent after SelectionChangedEvent but nothing changed.

Thoughts?

Thanks,

David
