Commit f60dee46 authored by Jeff Baumes's avatar Jeff Baumes

ENH: QtView class cleanup.

 - ENH: The adapter now handles vtk/qt selection conversion.

 - ENH: Removed lots of 'maps'

 - COMP: Fix ambiguous calls to createIndex by casting vtkIdType to int.

 - BUG: Fixing an over aggressive error message.

 - COMP: Use new selection conversion api in vtkQtAbstractModelAdapter.
