public class VMDGraphScene
extends GraphPinScene<String,String,String>

This class represents a GraphPinScene for the VMD visualization style. Nodes, edges and pins are represented using String class. The visualization is done by: VMDNodeWidget for nodes, VMDPinWidget for pins, ConnectionWidget fro edges.

The scene has 4 layers: background, main, connection, upper.

The scene has following actions: zoom, panning, rectangular selection.

Constructor Details

VMDGraphScene

public VMDGraphScene()

Creates a VMD graph scene.

VMDGraphScene

public VMDGraphScene(VMDColorScheme scheme)

Creates a VMD graph scene with a specific color scheme.

Parameters:

scheme - the color scheme

Method Details

attachNodeWidget

protected Widget attachNodeWidget(String node)

Implements attaching a widget to a node. The widget is VMDNodeWidget and has object-hover, select, popup-menu and move actions.

Specified by:

attachNodeWidget in class GraphPinScene<String,String,String>

Parameters:

node - the node

Returns:

the widget attached to the node

attachPinWidget

protected Widget attachPinWidget(String node,
 String pin)

Implements attaching a widget to a pin. The widget is VMDPinWidget and has object-hover and select action. The the node id ends with "#default" then the pin is the default pin of a node and therefore it is non-visual.

Specified by:

attachPinWidget in class GraphPinScene<String,String,String>

Parameters:

node - the node

pin - the pin

Returns:

the widget attached to the pin, null, if it is a default pin

attachEdgeWidget

protected Widget attachEdgeWidget(String edge)

Implements attaching a widget to an edge. the widget is ConnectionWidget and has object-hover, select and move-control-point actions.

Specified by:

attachEdgeWidget in class GraphPinScene<String,String,String>

Parameters:

edge - the edge

Returns:

the widget attached to the edge

attachEdgeSourceAnchor

protected void attachEdgeSourceAnchor(String edge,
 String oldSourcePin,
 String sourcePin)

Attaches an anchor of a source pin an edge. The anchor is a ProxyAnchor that switches between the anchor attached to the pin widget directly and the anchor attached to the pin node widget based on the minimize-state of the node.

Specified by:

attachEdgeSourceAnchor in class GraphPinScene<String,String,String>

Parameters:

edge - the edge

oldSourcePin - the old source pin

sourcePin - the new source pin

attachEdgeTargetAnchor

protected void attachEdgeTargetAnchor(String edge,
 String oldTargetPin,
 String targetPin)

Attaches an anchor of a target pin an edge. The anchor is a ProxyAnchor that switches between the anchor attached to the pin widget directly and the anchor attached to the pin node widget based on the minimize-state of the node.

Specified by:

attachEdgeTargetAnchor in class GraphPinScene<String,String,String>

Parameters:

edge - the edge

oldTargetPin - the old target pin

targetPin - the new target pin

layoutScene

public void layoutScene()

Invokes layout of the scene.
