[vtkusers] vtkGenericRenderWindowInteractor

[LOUIS-JORDAN DEERING (RIT Student)]

Hello All,

When I try to link the vtkGenericRenderWindowInteractor to the renWin, the window doesn't render until I click inside of it. How do I fix this? I need the Interactor to perform certain functions, but I need the window to render. If don't link the two together, the window renders correctly. They commented out block below is where I'm having trouble. Any suggestions? Thank you!
