Arrow-key press-events are not seen by vtkRenderWindowInteractor on Windows
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Why are arrow key-press events not forwarded to the vtkRenderWindowInteractor on Windows? Is there a workaround? Is there a general difference between arrow-key events on Windows and Mac?
I can reproduce the problem with the sample code attached. On Mac OS, I see 'Up', 'Down', 'Left' and 'Right' if I press the arrow keys. But on Windows, I don't see anything (the callback is not entered). I wondered why this is the case.
I use VTK 6.2.0 for python 2.7. I tested on Windows Server 2012 (similar to Windows 8) and Windows 7 (on a virtual machine), showing both the same behaviour.
