Constructor Summary

JGraphpadEdgeView.JGraphpadEdgeHandle(org.jgraph.graph.EdgeView edge, org.jgraph.graph.GraphContext ctx)
Constructs a new edge handle for the specified edge and context.

Method Summary

boolean	isAddPointEvent(MouseEvent event) Overrides the parent implementation to support the shift key to add points to edges.
boolean	isRemovePointEvent(MouseEvent event) Overrides the parent implementation to support the shift key to remove points from edges.
void	mousePressed(MouseEvent event) Overrides the parent implementation to reset the port offset if a remove event has been performed on either port.
protected void	processNestedMap(Map nested, boolean clone) Overrides the parent implementation to reset the port offset if the resetOffset flag is set.
protected boolean	snap(boolean isSource, Point2D point) Overrides the parent implementation to set the port offset if the mousepointer is over the port's parent view but not over the port's non-floating location (eg center).

Constructor Detail

JGraphpadEdgeView.JGraphpadEdgeHandle

public JGraphpadEdgeView.JGraphpadEdgeHandle(org.jgraph.graph.EdgeView edge,
                                             org.jgraph.graph.GraphContext ctx)

Constructs a new edge handle for the specified edge and context.

Parameters:

edge - The edge to create the handle for.

ctx - The context to use for the handle.

Method Detail

isRemovePointEvent

public boolean isRemovePointEvent(MouseEvent event)

Overrides the parent implementation to support the shift key to remove points from edges.

Parameters:

event - The object that describes the event.

Returns:

Returns true if the event is a remove point event.

isAddPointEvent

public boolean isAddPointEvent(MouseEvent event)

Overrides the parent implementation to support the shift key to add points to edges.

Parameters:

event - The object that describes the event.

Returns:

Returns true if the event is a add point event.

mousePressed

public void mousePressed(MouseEvent event)

Overrides the parent implementation to reset the port offset if a remove event has been performed on either port.

Parameters:

event - The object that describes the event.

snap

protected boolean snap(boolean isSource,
                       Point2D point)

Overrides the parent implementation to set the port offset if the mousepointer is over the port's parent view but not over the port's non-floating location (eg center).

Parameters:

isSource - Whether to snap the source or target port.

point - The point that should be used for snapping.

processNestedMap

protected void processNestedMap(Map nested,
                                boolean clone)

Overrides the parent implementation to reset the port offset if the resetOffset flag is set.

Parameters:

nested - The nested attribute map that is used to change the layout cache.

clone - Whether the control key was pressed.
