/**
* @class vtkContinuousValueWidget
* @brief set a value by manipulating something
*
* The vtkContinuousValueWidget is used to adjust a scalar value in an
* application. 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 details may
* vary depending on the particulars of the representation).
*
*
* @par Event Bindings:
* By default, the widget responds to the following VTK events (i.e., it
* watches the vtkRenderWindowInteractor for these events):
* <pre>
* If the slider bead is selected:
* LeftButtonPressEvent - select slider
* LeftButtonReleaseEvent - release slider
* MouseMoveEvent - move slider
* </pre>
*
* @par Event Bindings:
* Note that the event bindings described above can be changed using this
* class's vtkWidgetEventTranslator. This class translates VTK events
* into the vtkContinuousValueWidget's widget events:
* <pre>
* 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
* </pre>
*
* @par Event Bindings:
* In turn, when these widget events are processed, the vtkContinuousValueWidget
* invokes the following VTK events on itself (which observers can listen for):
* <pre>
* vtkCommand::StartInteractionEvent (on vtkWidgetEvent::Select)
* vtkCommand::EndInteractionEvent (on vtkWidgetEvent::EndSelect)
* vtkCommand::InteractionEvent (on vtkWidgetEvent::Move)
* </pre>
*
