Create a new instance of this manipulator. The new instance will have the same grab handle, and interactor for grab-handles, as this one.

Specified by:

newInstance in class FigureDecorator

refresh

public void refresh()

Refresh the geometry.

Specified by:

refresh in class Manipulator

setChild
