Hello everyone  
I tried to disable right click zoom function through

```auto
interactorStyle = slicer.app.layoutManager().sliceWidget('Red').sliceView().sliceViewInteractorStyle()
interactorStyle.SetActionEnabled(interactorStyle.Zoom, False)

```

but it can also lead to that I cannot observe mouse position change event in CrosshairNode

```auto
   self.mycrosshairNode = slicer.util.getNode('Crosshair')
   self.observationId_rightclick = self.mycrosshairNode.AddObserver(slicer.vtkMRMLCrosshairNode.CursorPositionModifiedEvent, self.mouse_move_event)

def mouse_move_event(self, observer, eventid):
    ras = [0, 0, 0]
    pos = self.interactor_red.GetEventPosition()
    self.mycrosshairNode.GetCursorPositionRAS(ras)
    print(ras)

```

Could you tell me how to only disable right click zoom function?

Due to a small bug, you need to re-enable cursor position setting after you disable any action:

```auto
interactorStyle = slicer.app.layoutManager().sliceWidget('Red').sliceView().sliceViewInteractorStyle()
interactorStyle.SetActionEnabled(interactorStyle.Zoom, False)
interactorStyle.SetActionEnabled(interactorStyle.SetCursorPosition, True)

```

We’ll fix this soon in the Slicer Preview Release, se this re-enabling `SetCursorPosition` will no longer be necessary.

I believe like this:

`interactorStyle = slicer.app.layoutManager().threeDWidget(0).threeDView().interactorStyle()`
