Constructor Detail

BendpointHandle

public BendpointHandle()

Method Detail

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)

setIndex

protected void setIndex(int i)

Sets the index.

Parameters:

i - the new index
