Window Size in vtkCanvas Does Not Affect Interactor
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
There is a bug in vtkCanvas (line 31), where the interactor is initially set to 200 by 200. Consequenty, when the window is initially set to be larger than 200 x 200, the screen coordinates of the mouse position returned by the interactor are off by 200.
Calling resize on a vtkPanel does not result in the correct size in the interactor. However, manually (expanding/shrinking the window with the mouse) resizing the window fixes this problem.
The work around that I've found is to set the interactor of the render window to the size of my window when I first create my window.
