[wxVTK] Proposal for patch to support 'Frozen' window

[Sander N. <nie...@st...>]

Hi Mathieu,

I would like to propose the following patch for wxVTK.

The patch contains the following changes:

- turn RenderAllowed in a local variable
There were no Set/Get methods for this variable anyway and its value  
was always reset at each call of Render().

- make explicit invocation of wxVTKRenderWindowInteractor::Render()  
dependent on Frozen state of wxWindow
This means that if you call Freeze() on a wxVTKRenderWindowInteractor,  
an invocation of Render() on the interactor will have no effect until  
the window has been 'thawed' again with Thaw().

Let me know if you agree with the patch.

P.S. I already have commit privileges.

Best regards,
Sander Niemeijer
