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
Steps To Reproduce
Additional Information_prop = new vtkTextProperty();
_scalarBarActor = new vtkScalarBarActor();
_scalarBarWidget = new vtkScalarBarWidget();
          
_prop.SetFontFamilyToArial();
_prop.SetFontSize(10);
_prop.SetColor(0,0,0);
_prop.SetJustificationToCentered();

_scalarBarActor.GetPositionCoordinate().SetCoordinateSystemToNormalizedViewport();
_scalarBarActor.SetPosition(.1, .1);
_scalarBarActor.SetOrientationToHorizontal();
_scalarBarActor.SetWidth(.8);
_scalarBarActor.SetHeight(0.17);
_scalarBarActor.SetLabelFormat("%g");
_scalarBarActor.SetLabelTextProperty(_prop);
_scalarBarActor.SetTextPositionToSucceedScalarBar();
_scalarBarActor.SetTitleTextProperty(_prop);

_scalarBarWidget.SetInteractor(ren.GetRenderWindow().GetInteractor());
_scalarBarWidget.SetCurrentRenderer(ren);
_scalarBarWidget.SetScalarBarActor(_scalarBarActor);

_scalarBarWidget.EnabledOn();


// Forcibly trying to change the widget does not work

_scalarBarWidget.GetScalarBarActor().SetHeight(.17);
_scalarBarWidget.GetScalarBarActor().SetWidth(.8);
_scalarBarWidget.GetScalarBarActor().SetPosition(.1, .1);
_scalarBarActor.Modified();
_scalarBarWidget.Modified();

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.
