Field Detail

_geometry

protected BoundsGeometry _geometry

The geometry "helper"

_dragInteractor

protected Interactor _dragInteractor

The interactor that is attached to a move handle.

Constructor Detail

BoundsManipulator

public BoundsManipulator()

Construct a new manipulator that uses rectangular grab-handles.

BoundsManipulator

public BoundsManipulator(GrabHandleFactory f)

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

Method Detail

getGeometry

protected BoundsGeometry getGeometry()

Return the geometry of this manipulator PWD: change protection to protected from private(!).

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.

Specified by:

newInstance in class FigureDecorator

refresh

public void refresh()

Refresh the geometry. This adjusts the bounds of the geometry to match the bounds of the child figure.

Specified by:

refresh in class Manipulator

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.

Overrides:

setChild in class FigureDecorator

setDragInteractor

public void setDragInteractor(Interactor dragger)

Set the drag interactor for figures wrapped by this manipulator. If set, the manipulator displays an additional handle that can be used to drag the figure. This is useful for certain types of figure that are outlines only.
