NodeView

public NodeView()

Method Detail

addGeometryObserver

public void addGeometryObserver(NodeGeometryObserver o)

By implementing the NodeGeometryObserver interface an EdgeView can register with this NodeView to be notified of any changes to its geometry so that it can update itself accordingly

Parameters:

o -

draw

public void draw()

Specified by:

draw in interface Viewable

getNode

public Node getNode()

Description copied from interface: NodeAbility

Get the Node that this ability is registered with

Specified by:

getNode in interface NodeAbility

setNode

public void setNode(Node node)

Description copied from interface: NodeAbility

Called by Node when this ability is registered with that node.

Specified by:

setNode in interface NodeAbility

getIcon

public javax.swing.ImageIcon getIcon()

Specified by:

getIcon in class GraphElementView

showLabel

protected void showLabel(java.lang.String text)

Specified by:

showLabel in class GraphElementView

showAnchor

public void showAnchor()

hideAnchor

public void hideAnchor()

getVWorldPosition

public javax.vecmath.Point3f getVWorldPosition()

getCanvasPosition

public java.awt.Point getCanvasPosition(java.awt.Component canvas)

Specified by:

getCanvasPosition in interface NodeView

Returns:

position of node on 2D canvas, removing all local transforms

moveToCanvasPos

public void moveToCanvasPos(GraphCanvas c,
                            int x,
                            int y)

Move the node in a plane parallel to the view plate, such that it appears at the point on the canvas specified in x and y. The x and y parameters are in AWT coordinates with 0,0 at the top left of the canvas.

Parameters:

c - the canvas

x - the x awt coordinate

y - the y awt coordinate

setColour

public void setColour(javax.vecmath.Color3f c)

When a new colour is set any GeometryObservers that have been added to this object will be notified

Overrides:

setColour in class GraphElementView

Parameters:

c - new colour for this NodeView
