[vtkusers] vtkRenderWindowInteractor::Initialize has a different behavior on windows and linux

[Joël Schaerer]

Hello all,

I am creating a vtkRenderWindow from a wxWidgets application. I don't
want vtk handling the main loop, so I only do Initialize() on the
Interactor and don't call Start(). On Windows, this has the desired
behavior: the interactor doesn't block program flow but still handles
events. On linux, the interactor doesn't seem to handle events and the
vtkRenderWindow never repaints.

Is this normal? Is there a workaround?

Many thanks
