[vtkusers] wxVTKRenderWindowInteractor Problem on Win32 [Resolved]

[Paul]

The code in my previous email didn't make much sense, sorry about
that. It was extricated/reduced from a larger program by a
temperamental monkey who didn't do a very good job (haven't fed him in
a while)..

It turns out that the problem is caused by "style = wx.SIMPLE_BORDER"
on the vtkrwi. It makes the vtkrwi window incorrectly grow in size
when you move or resize the containing frame under Windows.

If you add "style = wx.SIMPLE_BORDER" to the vtkrwi in
wxVTKRenderWindowInteractorConeExample() in
wxVTKRenderWindowInteractor.py you should see this behaviour (in
Windows). This could be symptomatic of a broader problem with wx.

So, don't use borders on wxVTKRenderWindowInteractor() until further notice.

For instance, if I drag the Window frame and move it around the screen, the render window inside gets progressively bigger. This size increase is reflected in the widget's reported size (panel.GetSize() < widget.GetSize()). The render window ("widget") seems to get sporadic OnSize() events as I drag around the containing frame around, although in principal it shouldn't. The sizes reported by event.GetSize() during the OnSize() events are wrong as well.
