3D widget for manipulating a finite, straight line
This 3D widget defines a straight line that can be interactively placed in a scene. The widget is assumed to consist of two parts: 1) two end points and 2) a straight line connecting the two points. (The representation paired with this widget determines the actual geometry of the widget.) The positioning of the two end points is facilitated by using vtkHandleWidgets to position the points.
To use this widget, you generally pair it with a vtkLineRepresentation (or a subclass). Various options are available in the representation for controlling how the widget appears, and how the widget functions.
If one of the two end points are selected: LeftButtonPressEvent - activate the associated handle widget LeftButtonReleaseEvent - release the handle widget associated with the point MouseMoveEvent - move the point If the line is selected: LeftButtonPressEvent - activate a handle widget accociated with the line LeftButtonReleaseEvent - release the handle widget associated with the line MouseMoveEvent - translate the line In all the cases, independent of what is picked, the widget responds to the following VTK events: MiddleButtonPressEvent - translate the widget MiddleButtonReleaseEvent - release the widget RightButtonPressEvent - scale the widget's representation RightButtonReleaseEvent - stop scaling the widget MouseMoveEvent - scale (if right button) or move (if middle button) the widget
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

Override superclasses' SetEnabled() method because the line widget must enable its internal handle widgets.
Reimplemented from vtkAbstractWidget.
|
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.

|
inline |
Return the representation as a vtkLineRepresentation.

Create the default widget representation if one is not set.
Implements vtkAbstractWidget.

virtual |
Methods to change the whether the widget responds to interaction. Overridden to pass the state to component widgets.
