public class InterpolatedCurveManipulator
extends Manipulator

A manipulator for InterpolatedCurveFigure figures. This attaches handles to the vertices of the curve and allows them to be moved, the corresponding InterpolatedCurveFigure should then re-draw itself with a new interpolation.

Field Detail

curve

protected InterpolatedCurveFigure curve

The InterpolatedCurveFigure.

curve2d

protected InterpolatedCurve2D curve2d

The InterpolatedCurve2D.

Constructor Detail

InterpolatedCurveManipulator

public InterpolatedCurveManipulator()

Construct a new manipulator that uses rectangular grab-handles.

InterpolatedCurveManipulator

public InterpolatedCurveManipulator(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 interactor for grab-handles, as this one.

Specified by:

newInstance in class FigureDecorator

refresh

public void refresh()

Refresh the underlying InterpolatedCurveFigure.

Specified by:

refresh in class Manipulator

paint

public void paint(Graphics2D g2d)

Description copied from class: Manipulator

Paint the manipulator. This default implementation first paints the child figure, and then paints each of the grab-handles.

Specified by:

paint in interface VisibleComponent

Overrides:

paint in class Manipulator

setChild

public void setChild(Figure f)

Set the child figure. If we have any grab-handles, lose them and create new ones.

Overrides:

setChild in class FigureDecorator

orderVertices

protected void orderVertices()

Make the X vertex coordinates monotonic and re-order the Vertex instances as appropriate.
