Detailed Description

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).

Event Bindings:

By default, the widget responds to the following VTK events (i.e., it watches the vtkRenderWindowInteractor for these events):

 If the slider bead is selected:
   LeftButtonPressEvent - select slider 
   LeftButtonReleaseEvent - release slider 
   MouseMoveEvent - move slider

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:

   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

Event Bindings:

In turn, when these widget events are processed, the vtkContinuousValueWidget invokes the following VTK events on itself (which observers can listen for):

   vtkCommand::StartInteractionEvent (on vtkWidgetEvent::Select)
   vtkCommand::EndInteractionEvent (on vtkWidgetEvent::EndSelect)
   vtkCommand::InteractionEvent (on vtkWidgetEvent::Move)

Events:: vtkCommand::EndInteractionEvent vtkCommand::InteractionEvent vtkCommand::StartInteractionEvent

void vtkContinuousValueWidget::SetRepresentation ( vtkContinuousValueWidgetRepresentation * r ) [inline]

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.

vtkContinuousValueWidgetRepresentation* vtkContinuousValueWidget::GetContinuousValueWidgetRepresentation ( ) [inline]

Return the representation as a vtkContinuousValueWidgetRepresentation.

double vtkContinuousValueWidget::GetValue ( )

Get the value for this widget.

void vtkContinuousValueWidget::SetValue ( double v )

Get the value for this widget.
