createDragTracker
protected DragTracker createDragTracker()
By default,null
is returned for the DragTracker.- Specified by:
createDragTracker
in classAbstractHandle
- Returns:
- returns null by default
-
getIndex
public int getIndex()
Returns the index. This could mean different things for different subclasses. It could be the index of the point the handle belongs to. Or it could be the index of the handle itself. ForBendpointCreationHandle
s andBendpointMoveHandle
s, this is the index of the handle itself, where these two types of handles are indexed separately. For example, if you have one bendpoint, you will have 2 creation handles, indexed as 0 and 1, and 1 move handle, indexed as 0.- Returns:
- the index
-
propertyChange
public void propertyChange(java.beans.PropertyChangeEvent event)
Revalidates this handle when the connection's points change.- Specified by:
propertyChange
in interfacejava.beans.PropertyChangeListener
- Overrides:
propertyChange
in classConnectionHandle
- Parameters:
event
- the event that caused the points change- See Also:
PropertyChangeListener.propertyChange(java.beans.PropertyChangeEvent)
-
setIndex
protected void setIndex(int i)
Sets the index.- Parameters:
i
- the new index- See Also:
getIndex()
