Detailed Description

measure the distance between two points

The vtkDistanceWidget is used to measure the distance between two points. The two end points can be positioned independently, and when they are released, a special PlacePointEvent is invoked so that special operations may be take to reposition the point (snap to grid, etc.) The widget has two different modes of interaction: when initially defined (i.e., placing the two points) and then a manipulate mode (adjusting the position of the two points).

To use this widget, specify an instance of vtkDistanceWidget and a representation (a subclass of vtkDistanceRepresentation). The widget is implemented using two instances of vtkHandleWidget which are used to position the end points of the line. The representations for these two handle widgets are provided by the vtkDistanceRepresentation.

Event Bindings:
By default, the widget responds to the following VTK events (i.e., it watches the vtkRenderWindowInteractor for these events):
  LeftButtonPressEvent - add a point or select a handle
  MouseMoveEvent - position the second point or move a handle
  LeftButtonReleaseEvent - release the handle
Event Bindings:
Note that the event bindings described above can be changed using this class's vtkWidgetEventTranslator. This class translates VTK events into the vtkDistanceWidget's widget events:
  vtkWidgetEvent::AddPoint -- add one point; depending on the state
                              it may the first or second point added. Or,
                              if near a handle, select the handle.
  vtkWidgetEvent::Move -- move the second point or handle depending on the state.
  vtkWidgetEvent::EndSelect -- the handle manipulation process has completed.
Event Bindings:
This widget invokes the following VTK events on itself (which observers can listen for):
  vtkCommand::StartInteractionEvent (beginning to interact)
  vtkCommand::EndInteractionEvent (completing interaction)
  vtkCommand::InteractionEvent (moving after selecting something)
  vtkCommand::PlacePointEvent (after point is positioned;
                               call data includes handle id (0,1))

The method for activating and deactivating this widget.

This method must be overridden because it is a composite widget and does more than its superclasses' vtkAbstractWidget::SetEnabled() method.

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.

Methods to change the whether the widget responds to interaction.

Overridden to pass the state to component widgets.

Reimplemented from vtkAbstractWidget.

◆ SetWidgetStateToStart()

virtual void vtkDistanceWidget::SetWidgetStateToStart ( )
virtual

Set the state of the widget.

If the state is set to "Manipulate" then it is assumed that the widget and its representation will be initialized programmatically and is not interactively placed. Initially the widget state is set to "Start" which means nothing will appear and the user must interactively place the widget with repeated mouse selections. Set the state to "Start" if you want interactive placement. Generally state changes must be followed by a Render() for things to visually take effect.

◆ SetWidgetStateToManipulate()

virtual void vtkDistanceWidget::SetWidgetStateToManipulate ( )
virtual

Set the state of the widget.

If the state is set to "Manipulate" then it is assumed that the widget and its representation will be initialized programmatically and is not interactively placed.
