[vtkusers] Autodesk ViewCube in VTK?

[Justin Weber]

I tried to access the mouse events of vtkOrientationMarkerWidget by adding
observers, however this does not seem to work.

class CustomOrientationMarkerWidget(vtk.vtkOrientationMarkerWidget):

    def __init__(self, parent=None):
        self.AddObserver("LeftButtonPressEvent",
self.left_button_press_event)

    def left_button_press_event(self, obj, event):
        print('pressed')

any ideas?
