IFigure
- public class PolylineConnection
- extends
Polyline
- implements
Connection,
AnchorListener
An implementation of
Connection based on Polyline. PolylineConnection adds
the following additional features:
-
A
ConnectionRouter may be provided which will be used to determine the
connections points.
-
Children may be added. The bounds calculation is extended such that the bounds is
the smallest Rectangle which is large enough to display the Polyline and all of its
children figures.
-
A
DelegatingLayout is set as the default layout. A delegating layout allows
children to position themselves via
Locators.
