Constructor and Description
EditingGraphMousePlugin(org.apache.commons.collections4.Factory<V> vertexFactory, org.apache.commons.collections4.Factory<E> edgeFactory)
EditingGraphMousePlugin(int modifiers, org.apache.commons.collections4.Factory<V> vertexFactory, org.apache.commons.collections4.Factory<E> edgeFactory) create instance and prepare shapes for visual effects

Method Summary

Modifier and Type	Method and Description
boolean	checkModifiers(MouseEvent e) Overridden to be more flexible, and pass events with key combinations.
void	mouseClicked(MouseEvent e)
void	mouseDragged(MouseEvent e) If startVertex is non-null, stretch an edge shape between startVertex and the mouse pointer to simulate edge creation
void	mouseEntered(MouseEvent e)
void	mouseExited(MouseEvent e)
void	mouseMoved(MouseEvent e)
void	mousePressed(MouseEvent e) If the mouse is pressed in an empty area, create a new vertex there.
void	mouseReleased(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.

Method Detail

checkModifiers

public boolean checkModifiers(MouseEvent e)

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

Specified by:

checkModifiers in interface GraphMousePlugin

Overrides:

checkModifiers in class AbstractGraphMousePlugin

Parameters:

e - an event to compare to

Returns:

whether the member modifers match the event modifiers

mousePressed

public void mousePressed(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 MouseListener

mouseReleased

public void mouseReleased(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 MouseListener

mouseDragged

public void mouseDragged(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 MouseMotionListener

mouseClicked

public void mouseClicked(MouseEvent e)

Specified by:

mouseClicked in interface MouseListener

mouseEntered

public void mouseEntered(MouseEvent e)

Specified by:

mouseEntered in interface MouseListener

mouseExited

public void mouseExited(MouseEvent e)

Specified by:

mouseExited in interface MouseListener

mouseMoved

public void mouseMoved(MouseEvent e)

Specified by:

mouseMoved in interface MouseMotionListener
