- All Implemented Interfaces:
GraphMousePlugin
,MouseListener
,MouseMotionListener
,EventListener
public class EditingGraphMousePlugin<V,E>
extends AbstractGraphMousePlugin
implements MouseListener, MouseMotionListener
A plugin that can create vertices, undirected edges, and directed edges
using mouse gestures.
vertexSupport and edgeSupport member classes are responsible for actually
creating the new graph elements, and for repainting the view when changes
were made.

checkModifiers
Overridden to be more flexible, and pass events with key combinations. The default responds to both ButtonOne and ButtonOne+Shift- Specified by:
checkModifiers
in interfaceGraphMousePlugin
- Overrides:
checkModifiers
in classAbstractGraphMousePlugin
- Parameters:
e
- an event to compare to- Returns:
- whether the member modifiers match the event modifiers
-
mousePressed
If the mouse is pressed in an empty area, create a new vertex there. If the mouse is pressed on an existing vertex, prepare to create an edge from that vertex to another- Specified by:
mousePressed
in interfaceMouseListener
-
mouseReleased
If startVertex is non-null, and the mouse is released over an existing vertex, create an undirected edge from startVertex to the vertex under the mouse pointer. If shift was also pressed, create a directed edge instead.- Specified by:
mouseReleased
in interfaceMouseListener
-
mouseDragged
If startVertex is non-null, stretch an edge shape between startVertex and the mouse pointer to simulate edge creation- Specified by:
mouseDragged
in interfaceMouseMotionListener
-
mouseClicked
