// .NAME vtkQtRecordView - Superclass for QAbstractItemView-based views.
//
// .SECTION Description
// This superclass provides all the plumbing to integrate a QAbstractItemView 
// into the VTK view framework, including reporting selection changes and 
// detecting selection changes from linked views.
//
// .SECTION Thanks
// Thanks to Brian Wylie from Sandia National Laboratories for implementing
// this class
