Method Summary

void	connectorDragged(ConnectorEvent e) Called when a connector end is dragged.
void	connectorDropped(ConnectorEvent e) Called when a connector end is dropped.
void	connectorSnapped(ConnectorEvent e) Called when a connector end is snapped to a possible target.
void	connectorUnsnapped(ConnectorEvent e) Called when a connector end is unsnapped from the site that it was originally attached to, or a possible target.

Method Detail

connectorDragged

void connectorDragged(ConnectorEvent e)

Called when a connector end is dragged. If currently over a target (and regardless of whether the connector is snapped to that target), the source field will be non-null.

connectorDropped

void connectorDropped(ConnectorEvent e)

Called when a connector end is dropped. If the connector is currently snapped to a target, the target can be obtained from the event as the source field.

connectorSnapped

void connectorSnapped(ConnectorEvent e)

Called when a connector end is snapped to a possible target. The target can be obtained as the source field of the event.

connectorUnsnapped

void connectorUnsnapped(ConnectorEvent e)

Called when a connector end is unsnapped from the site that it was originally attached to, or a possible target. The figure that it was unsnapped from is the source field of the event.
