[vtk-developers] create a widget vs the camera

[Will Schroeder]

It sounds to me like the widget you created is observing / capturing all
events, even the ones that are not meant for your new widget (i.e., events
never propagate to the vtkRenderWindowInteractor and its style class e.g.
vtkInteractorStyleJoystickCamera or equivalent). Yes, new widgets have to
specify which events they process, and then process them appropriately.

Why are you not using vtkHandleWidget and vtkPointHandleRepresentation3D or
something similar? These are typically used to move points around.
