[vtkusers] vtkRenderWindowInteractor does not process key events

[Daniel Lüken]

Odd. It works quite fine for me. (vtk5, c++, win32 api gui)

Speaking of the interactor, do you also find that it is not using
SetCapture()? It seems if I click in the renderer and start rotating
the camera, then move the mouse outside the window boundaries, the
interactor locks - until the mouse moves back within the window
boundaries. I know a call to SetCapture() would fix this but shouldn't
it be happening in the interactor already for windows platforms?

Thanks,
Mark
