[vtkusers] QVTKWidget and size of actor/renderwindow

[Eric E. Monson]

There was this recent mailing list thread:

http://markmail.org/message/ju7ei75tdjdqzhcn

which also references an example from the Wiki (for setting image to the background of the window) and another recent mailing list thread.

Maybe those will help, too.

I also checked the render window's size, but the size seems correct (ie 500*500 in my case). I'm using vtkImageReslice to reslice the volume and I'm setting the OutputExtent with the size I want (500*500).
