Summary0007430: vtkScalarBarWidget does not take position, width and height from vtkScalarBarActor
DescriptionI am creating a vtkScalarBarActor and a vtkScalarBarWidget to handle interaction with a scalar bar. Even though the position, width and height properties of the scalar bar are set the widget displays the scalar bar as a square in the bottom right corner. Further interaction with the widgit produces normal results but I am unable to force the widget to be a certain size.

Also I have attached a vtkTextProperty but the text still changes font size as the window changes size. It would be nice if it didn't do that.

Thanks in advance,
Sarah

 In the new widget/representation classes, the representation is responsible for controlling the size of the scalar bar. It, too, does not get the width, height, or position from the vtkScalarBarActor.
