PathManipulator
public PathManipulator()
- Construct a new manipulator that uses rectangular grab-handles.
PathManipulator
public PathManipulator(GrabHandleFactory f)
- Construct a new manipulator using the given grab-handle factory.
newInstance
public FigureDecorator newInstance(Figure f)
- Create a new instance of this manipulator. The new
instance will have the same grab handle, and interactor
for grab-handles, as this one.

newInstance
in class FigureDecorator
refresh
public void refresh()
- Refresh the geometry.
- Specified by:
