[wxVTK] Crash with wxVTKRWI as a wxAuiManager pane

[Juha-Ville J. <jul...@gm...>]

Hello,

Not sure if this is the right place to report possible bugs ? Anyways:

I'm using a wxVTKRenderWindowInteractor as a wxAUIManager pane. When trying
to undock the pane I get crash with

...
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 54 error_code 3 request_code 12 minor_code 0)
...

This happens on both GTK2 and MSW versions.

After a bit of debugging I found out that the crash happens on this line in
wxVTKRenderWindowInteractor::UpdateSize(int x, int y):

    RenderWindow->SetSize(x, y);

and only when x = y = 20  !?

Seems that when the undock/drag starts the dragged wxWindow/wxAUI pane is
sets to some minimum size that happens to be 20 and is not taken nicely by
RenderWindow->SetSize ?!

I was able solve this problem by  following temporary hack:

      if (x!=20 && y!=20) RenderWindow->SetSize(x, y);

I'm using wxGTK 2.8.7, wxVTK version is (wxVTKRWI.cxx)
