Adjust Window Level is not working (nightly release 4.11.0)

Support

In the latest nigthly release (13-05-2019, windows), adjusting window/level by left-click + dragging is not working anymore. It is still possible to adjust window/level through the Volumes module however.

Furthermore, when checking the interactorstyle, it shows that AdjustWindowLevelForeground and AdjustWindowLevelBackground are enabled.

>>> interactorStyle = slicer.app.layoutManager().sliceWidget('Red').sliceView().sliceViewInteractorStyle()
>>> interactorStyle.GetActionEnabled(interactorStyle.AdjustWindowLevelForeground)
True
>>> interactorStyle.GetActionEnabled(interactorStyle.AdjustWindowLevelBackground)
True

HI Joost,

Mouse modes have recently changed. To window/level you need to switch to W/L mode by clicking on the button on the toolbar that is activated in this screenshot:

@cpinter Thanks! Is there a way to set the default to W/L adjustment on startup?

You can put this in the slicerrc.py

appLogic = slicer.app.applicationLogic()
interactionNode = appLogic.GetInteractionNode()
interactionNode.SetCurrentInteractionMode(slicer.vtkMRMLInteractionNode.AdjustWindowLevel)
