[vtkusers] Basic question about widgets

[Mike Gagnon]

Hi,

I'm learning about widgets and tried to create a vtkSliderWidget.  I 
have an existing renderer and interactor with actors already in my scene 
etc.

I have the following code:
m_pSliderRep->GetPoint1Coordinate()->SetCoordinateSystemToDisplay();
     m_pSliderRep->GetPoint1Coordinate()->SetValue(100,50,0);
m_pSliderRep->GetPoint2Coordinate()->SetCoordinateSystemToDisplay();
     m_pSliderRep->GetPoint2Coordinate()->SetValue(400,50,0);

I want the slider to stay at the bottom left, but when I left click with 
the mouse, my existing actor rotates as before, but so does the slider - 
and then it snaps back into place at the bottom left but the text is 
backwards on the slider (or rotated even).  Can anyone tell me what I'm 
missing?

Thanks,
Mike
