set a value by manipulating a slider
The vtkCenteredSliderWidget is used to adjust a scalar value in an application. This class measures deviations form the center point on the slider. Moving the slider modifies the value of the widget, which can be used to set parameters on other objects. Note that the actual appearance of the widget depends on the specific representation for the widget.
To use this widget, set the widget representation. The representation is assumed to consist of a tube, two end caps, and a slider (the details may vary depending on the particulars of the representation). Then in the representation you will typically set minimum and maximum value, as well as the current value. The position of the slider must also be set, as well as various properties.
Note that the value should be obtain from the widget, not from the representation. Also note that Minimum and Maximum values are in terms of value per second. The value you get from this widget's GetValue method is multiplied by time.
If the slider bead is selected: LeftButtonPressEvent - select slider (if on slider) LeftButtonReleaseEvent - release slider (if selected) MouseMoveEvent - move slider If the end caps or slider tube are selected: LeftButtonPressEvent - move (or animate) to cap or point on tube;
vtkWidgetEvent::Select -- some part of the widget has been selected vtkWidgetEvent::EndSelect -- the selection process has completed vtkWidgetEvent::Move -- a request for slider motion has been invoked

Specify an instance of vtkWidgetRepresentation used to represent this widget in the scene. Note that the representation is a subclass of vtkProp so it can be added to the renderer independent of the widget.
