[vtkusers] VTK tutorial, step 5 (Cone5), OSX-Cocoa: fails to capture keyboard events

[Michael Jackson]

But aren't there times when you want to make the OpenGL context the  
current context but NOT bring the window to the front? Your code would  
do that, which might be a bit annoying.

  The code I submitted is designed for _you_ to put in _your_ code and  
NOT into any of the vtk code. Well maybe the cone examples and stuff  
like that but NOT the render classes.

  I also may be way wrong on that but last time I ran my code the code  
worked just fine with keyboard events and all.
