Hi Dr  Ingo,

Thanks for your quick and helpful reply. Based on your suggestion, my
code works now.

But I also got another question:

How to change the colour of the "picked" cell which is implemented by 
vtkCellPicker?
I work with a 3D vtkPolyData model.

Thanks in advance.

Tracy

Hi Tracy,

you get "-1" because you didn't start the picker callback.
with StartPickCallback. Look at the lines of vtkInteractorStyle.cxx:
Search for "'p'". This is what happens, when you press "p". Your version
works with LeftButtonPressEvent when you press "p" before you press the
left mouse button.

The easiest way for you would be to write your own interactor.

greets
  Ingo
