[vtkusers] How to intercept Window Size Change Event

[Sebastian Gatzka]

Yes you can drag it past 400.
And if it reaches 0 the window will crash.
It's due to implicit plane widgets representation of the plane origin (a
sphere) in my case.
I think it will get a 0-radius with 0-sized window and will send the code
flying ...

Here is an example:
http://www.vtk.org/Wiki/VTK/Examples/WindowModifiedEvent

The window horizontal size is limited to 400. However, it will let you
drag it past that, it just snaps back when you release the mouse.

Anyone know if it can be limited before it goes past 400?

Thanks,

David
