Constructor Detail

BendpointHandle

public BendpointHandle()
Method Detail

addNotify

public void addNotify()
Adds a PropertyChangeListener to this handle's owner figure (a Connection), so that the handle can be revalidated when the Connection's points change.

Specified by:
addNotify in interface IFigure
Overrides:
addNotify in class ConnectionHandle

createDragTracker

protected DragTracker createDragTracker()
By default, null is returned for the DragTracker.

Specified by:
createDragTracker in class AbstractHandle
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. For BendpointCreationHandles and BendpointMoveHandles, 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(PropertyChangeEvent event)
Revalidates this handle when the connection's points change.

Specified by:
propertyChange in interface PropertyChangeListener
Overrides:
propertyChange in class ConnectionHandle
Parameters:
event - the event that caused the points change
See Also:
PropertyChangeListener.propertyChange(java.beans.PropertyChangeEvent)

removeNotify

public void removeNotify()
Removes this PropertyChangeListener from its owner figure.

Specified by:
removeNotify in interface IFigure
Overrides:
removeNotify in class ConnectionHandle
See Also:
IFigure.removeNotify()

setIndex

protected void setIndex(int i)
Sets the index.

See Also:
getIndex()
