Class LinkEditor

java.lang.Object
  edu.uci.ics.jung.visualization.control.AbstractGraphMousePlugin
      com.alveole.studio.web.designer.LinkEditor

All Implemented Interfaces:

edu.uci.ics.jung.visualization.control.GraphMousePlugin, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.util.EventListener

public class LinkEditor
extends edu.uci.ics.jung.visualization.control.AbstractGraphMousePlugin
implements java.awt.event.MouseListener, java.awt.event.MouseMotionListener

A plugin that can create vertices, undirected edges, and directed edges using mouse gestures. This class was imported from JUNG project and modified to integrate callbacks to GuiActionsManager, when a link is created.

Constructor Detail

LinkEditor

public LinkEditor(GuiActionsManager manager)

LinkEditor

public LinkEditor(GuiActionsManager manager,
                  int modifiers)

create instance and prepare shapes for visual effects

Parameters:

modifiers -

Method Detail

checkModifiers

public boolean checkModifiers(java.awt.event.MouseEvent e)

overrided to be more flexible, and pass events with key combinations. The default responds to both ButtonOne and ButtonOne+Shift

Specified by:

checkModifiers in interface edu.uci.ics.jung.visualization.control.GraphMousePlugin

Overrides:

checkModifiers in class edu.uci.ics.jung.visualization.control.AbstractGraphMousePlugin

mousePressed

public void mousePressed(java.awt.event.MouseEvent e)

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 interface java.awt.event.MouseListener

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent e)

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 interface java.awt.event.MouseListener

mouseDragged

public void mouseDragged(java.awt.event.MouseEvent e)

If startVertex is non-null, stretch an edge shape between startVertex and the mouse pointer to simulate edge creation

Specified by:

mouseDragged in interface java.awt.event.MouseMotionListener

mouseClicked

public void mouseClicked(java.awt.event.MouseEvent e)

Specified by:

mouseClicked in interface java.awt.event.MouseListener

mouseEntered

public void mouseEntered(java.awt.event.MouseEvent e)

Specified by:

mouseEntered in interface java.awt.event.MouseListener

mouseExited

public void mouseExited(java.awt.event.MouseEvent e)

Specified by:

mouseExited in interface java.awt.event.MouseListener

mouseMoved

public void mouseMoved(java.awt.event.MouseEvent e)

Specified by:

mouseMoved in interface java.awt.event.MouseMotionListener

isEdgeIsDirected

public boolean isEdgeIsDirected()

setEdgeIsDirected

public void setEdgeIsDirected(boolean edgeIsDirected)
