Constructor Detail

RangeManipulator

public RangeManipulator()

Construct a new manipulator that uses rectangular grab-handles.

RangeManipulator

public RangeManipulator(GrabHandleFactory f)

Construct a new manipulator using the given grab-handle factory.

Method Detail

newInstance

public FigureDecorator newInstance(Figure f)

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

Overrides:

newInstance in class BoundsManipulator

setChild

public void setChild(Figure child)

Set the child figure. If we have any grab-handles, lose them. Then get a rectangle geometry object and create grab-handles on its sites. Override to modify Geometry object, so we can match "range" rather than "bounds" handles.

Overrides:

setChild in class BoundsManipulator
