Field Detail

vertex

protected V vertex

the picked Vertex, if any

edge

protected E edge

the picked Edge, if any

offsetx

protected double offsetx

the x distance from the picked vertex center to the mouse point

offsety

protected double offsety

the y distance from the picked vertex center to the mouse point

locked

protected boolean locked

controls whether the Vertices may be moved with the mouse

rect

protected Rectangle2D rect

used to draw a rectangle to contain picked vertices

lensPaintable

protected edu.uci.ics.jung.visualization.VisualizationServer.Paintable lensPaintable

the Paintable for the lens picking rectangle

lensColor

protected Color lensColor

color for the picking rectangle

Constructor Detail

VerticesPickingGraphMousePlugin

public VerticesPickingGraphMousePlugin()

Create an instance with default settings.

Method Detail

getLensColor

public Color getLensColor()

Returns:

Returns the lensColor.

setLensColor

public void setLensColor(Color lensColor)

Parameters:

lensColor - The lensColor to set.

mousePressed

public void mousePressed(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 MouseListener

Parameters:

e - the event

mouseReleased

public void mouseReleased(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 MouseListener

mouseDragged

public void mouseDragged(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:

mouseDragged in interface MouseMotionListener

pickContainedVertices

protected void pickContainedVertices(edu.uci.ics.jung.visualization.VisualizationViewer<V,E> vv,
                                     Point2D down,
                                     Point2D out,
                                     boolean clear)

pick the vertices inside the rectangle created from points 'down' and 'out'
