[vtkusers] vtkScalarbarWidget

[Eric E. Monson]

Hey Rakesh,

Here's an example (Python) of how I set up the vtkScalarBarWidget. I did the sizing by setting the "position coordinates" (relative to window size) on the representation:

vertexScalarBar = vtk.vtkScalarBarWidget()
vertexScalarBar.SetInteractor(iren)
vertexScalarBar.SetDefaultRenderer(view.GetRenderer())
vertexScalarBar.SetCurrentRenderer(view.GetRenderer())
vertexScalarBar.SetEnabled(True)
sbActor = vertexScalarBar.GetScalarBarActor()
sbActor.SetLookupTable(vertMapper.GetLookupTable())
sbActor.SetTitle(vertMapper.GetArrayName())
sbActor.SetNumberOfLabels(3)
scalarBarRep = vertexScalarBar.GetRepresentation()
scalarBarRep.SetOrientation(1)  # 0 = Horizontal, 1 = Vertical
scalarBarRep.GetPositionCoordinate().SetValue(0.05,0.05)
scalarBarRep.GetPosition2Coordinate().SetValue(0.15,0.25)
