[vtkusers] How to customize mouse actions on vtkImagePlaneWidget?

[Wagner Sales]

Hi Dean,

Thnks. This aproach can solve my problem now.
But, I think if you have a widget with interactions, probably sometimes 
you'll need override another interactions in this widget by implement an 
application requirement. I think certanly that's are possible to do and 
I was taked a look at http://www.vtk.org/Wiki/VTKWidgets#Basic_Concepts, 
but I'm little bit confused ( i'm not a c++ guru, and since I use qt, 
i'm not familiarized with callbacks and event implementation in VTK ). 
Because that, if someone can give a start point to learn about that, or 
a little example how to override events manipulation, to me will be very 
useful.

Thnks in advance,

Wagner Sales
