Class ChopboxAnchor
java.lang.Object
org.eclipse.draw2d.ConnectionAnchorBase
org.eclipse.draw2d.AbstractConnectionAnchor
org.eclipse.draw2d.ChopboxAnchor
- All Implemented Interfaces:
AncestorListener
,ConnectionAnchor
- Direct Known Subclasses:
LabelAnchor
,RoundedRectangleAnchor
The ChopboxAnchor's location is found by calculating the intersection of a
line drawn from the center point of its owner's box to a reference point on
that box. Thus
Connections
using the ChopBoxAnchor will be
oriented such that they point to their owner's center.-

Method Details
-
getLocation
Gets a Rectangle fromgetBox()
and returns the Point where a line from the center of the Rectangle to the Point reference intersects the Rectangle.- Parameters:
reference
- The reference point- Returns:
- The anchor location
-
getBox
Returns the bounds of this ChopboxAnchor's owner. Subclasses can override this method to adjust the box the anchor can be placed on. For instance, the owner figure may have a drop shadow that should not be included in the box.- Returns:
- The bounds of this ChopboxAnchor's owner
- Since:
- 2.0
-
getReferencePoint
Returns the anchor's reference point. In the case of the ChopboxAnchor, this is the center of the anchor's owner.- Specified by:
getReferencePoint
in interfaceConnectionAnchor
- Overrides:

in classAbstractConnectionAnchor
- Returns:
- The reference point
