Class PickingGraphMousePlugin<V,E>

java.lang.Object

edu.uci.ics.jung.visualization.control.AbstractGraphMousePlugin

edu.uci.ics.jung.visualization.control.PickingGraphMousePlugin<V,E>

All Implemented Interfaces:

GraphMousePlugin, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.util.EventListener

public class PickingGraphMousePlugin<V,E>
extends AbstractGraphMousePlugin
implements java.awt.event.MouseListener, java.awt.event.MouseMotionListener

PickingGraphMousePlugin supports the picking of graph elements with the mouse. MouseButtonOne picks a single vertex or edge, and MouseButtonTwo adds to the set of selected Vertices or EdgeType. If a Vertex is selected and the mouse is dragged while on the selected Vertex, then that Vertex will be repositioned to follow the mouse until the button is released.

Constructor Detail

PickingGraphMousePlugin

public PickingGraphMousePlugin()

create an instance with default settings

PickingGraphMousePlugin

public PickingGraphMousePlugin(int selectionModifiers,
                               int addToSelectionModifiers)

create an instance with overides

Parameters:

selectionModifiers - for primary selection

addToSelectionModifiers - for additional selection

Method Detail

getLensColor

public java.awt.Color getLensColor()

Returns:

Returns the lensColor.

setLensColor

public void setLensColor(java.awt.Color lensColor)

Parameters:

lensColor - The lensColor to set.

mousePressed

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

For primary modifiers (default, MouseButton1): pick a single Vertex or Edge that is under the mouse pointer. If no Vertex or edge is under the pointer, unselect all picked Vertices and edges, and set up to draw a rectangle for multiple selection of contained Vertices. For additional selection (default Shift+MouseButton1): Add to the selection, a single Vertex or Edge that is under the mouse pointer. If a previously picked Vertex or Edge is under the pointer, it is un-picked. If no vertex or Edge is under the pointer, set up to draw a multiple selection rectangle (as above) but do not unpick previously picked elements.

Specified by:

mousePressed in interface java.awt.event.MouseListener

Parameters:

e - the event

mouseReleased

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

If the mouse is dragging a rectangle, pick the Vertices contained in that rectangle clean up settings from mousePressed

Specified by:

mouseReleased in interface java.awt.event.MouseListener

mouseDragged

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

If the mouse is over a picked vertex, drag all picked vertices with the mouse. If the mouse is not over a Vertex, draw the rectangle to select multiple Vertices

Specified by:
