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))
