I know you have a flag for this already but I preferr to keep the hide/show flag separate from the creation flag.

At the time I did not find a way to hide the slider widget, which you seem to have found. I used EnabledOn.

Lines 1565 to 1569 in cf6cb86

	sw = vtk.vtkSliderWidget()
	sw.SetInteractor(self.getInteractor())
	sw.SetRepresentation(sr)
	sw.SetAnimationModeToAnimate()
	sw.EnabledOn()

It would be useful to add a method setSliderWidgetEnabled to be able to control the visibility of the slider widget. This would allow a proper treatment of the visibility and creation of the widget.

I did not create a new method to control the visibility as the SetEnabled method already exists. The creation of the widget in a viewer is a different matter. I was not sure what you wanted to do with the enabled parameter. Perhaps we can discuss this in a meeting.
