Constructor Detail

GroupFigure

public GroupFigure()

Creates a new instance.

Method Detail

chop

public java.awt.geom.Point2D.Double chop(java.awt.geom.Point2D.Double from)

This is a default implementation that chops the point at the rectangle returned by getBounds() of the figure.

Figures which have a non-rectangular shape need to override this method.

FIXME Invoke chop on each child and return the closest point.

isTransformable

public boolean isTransformable()

Returns true if all children of the group are transformable.

Specified by:

isTransformable in interface Figure

Overrides:

isTransformable in class AbstractFigure
