[vtkusers] PropPicker

[Rashed Karim]

Hi everyone ..

I am finding it difficult to set a callback for a vtkPropPicker .. is this
what i do:

vtkPropPicker *picker = vtkPropPicker::New( );
picker->InitializePickList( );
picker->AddPickList( someActor );
.....

vtkCallbackCommand *cbc_pickcells = vtkCallbackCommand::New();
cbc_pickcells->SetCallback(PickCells);
picker->AddObserver(vtkCommand::EndPickEvent, cbc_pickcells);

When i hit the ''p' button on the rendering window, the callback function is
not getting called. Anyone suspect anything I could be doing wrong here?

Best Regards,
