[vtkusers] QVTKWidget mouse event in python

[Eric E. Monson]

Hey Nicola,

I haven't used this myself, so hopefully someone else can also help with more details, but I think what you need to use is vtkEventQtSlotConnect:

http://www.vtk.org/doc/nightly/html/classvtkEventQtSlotConnect.html

On that page there are links to two examples (C++) and a test (Python). The Python test is pretty minimal, so you'll probably have to look at those cxx tests to get more ideas of how to use it. I think the Qt events example in [vtk_src]/Examples/GUI/Qt/Events/GUI4.cxx will be most useful.

Good luck,
-Eric
