// .NAME vtkContinuousValueWidget - set a value by manipulating something
// .SECTION Description
// 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).
//
//
// .SECTION 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>
//
// 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>
//
// 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>
//
