I'm not sure what that code snippet does, but this is totally not the right way to resize any widget. <br><br>The slider representation has a Point1Coordinate and a Point2Coordinate. These define the end points of the slider (in normlized coordinates [-1, 1]). These iVars just aren't exposed. Modify the code yourself (or derive from vtkSliderRepresentation2D) and expose them so as to resize the widget.<br>
