[vtkusers] RE: Windows 2000 - Resize

Hi Meintjes,

Sounds like you've tried all the usual vtk-based fixes!

The above image appears to be taken when the vtk window
is maximized.  Is the resizing behaviour correct when
the vtk window is "resizable", e.g. not maximized?

Some thoughts:  

Has anyone else had this problem under Win2000?

Has the way Vtk uses Win32::OpenGL changed between the 
time it last worked for you, and your current problem?

How about the OpenGL drivers for your graphics card?

How about the amount of video memory the card has?  
To run hardware-accelerated double-buffered OpenGL at 
1024x768, I think requires at least 8MB video memory.

Is it possible that when Vtk last worked for you under 
Win2000, your machine was doing OpenGL in software rather 
than hardware?  What sort of graphics card, and which 
drivers are you using?  

A mystery!  Cannot sleep 'till solution found  :-)

Nigel.
