How do I close window adjusting of vtkResliceCursorWidget

I’m trying to change the FourPaneViewer project that comes with vtk, but I’m finding that I can’t turn off the window adjusting and zoom of the vtkResliceCursorWidget. The class doesn’t seem to provide a public function to turn it off either!
vtk version 9.0.3, qt version 5.12, vs2015
