public class VMDGraphScene
extends GraphPinScene<java.lang.String,java.lang.String,java.lang.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.

    scheme - the color scheme
- Method Detail
  - attachNodeWidget
```
protected Widget attachNodeWidget(java.lang.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<java.lang.String,java.lang.String,java.lang.String>
    
    Parameters:
    
    node - the node
    
    Returns:
    
    the widget attached to the node
  - attachPinWidget
```
protected Widget attachPinWidget(java.lang.String node,
                                 java.lang.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<java.lang.String,java.lang.String,java.lang.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(java.lang.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<java.lang.String,java.lang.String,java.lang.String>
    
    Parameters:
    
    edge - the edge
    
    Returns:
    
    the widget attached to the edge
  - attachEdgeSourceAnchor
```
protected void attachEdgeSourceAnchor(java.lang.String edge,
                                      java.lang.String oldSourcePin,
                                      java.lang.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<java.lang.String,java.lang.String,java.lang.String>
    
    Parameters:
    
    edge - the edge
    
    oldSourcePin - the old source pin
    
    sourcePin - the new source pin
  - attachEdgeTargetAnchor
```
protected void attachEdgeTargetAnchor(java.lang.String edge,
                                      java.lang.String oldTargetPin,
                                      java.lang.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<java.lang.String,java.lang.String,java.lang.String>
    
    Parameters:
    
    edge - the edge
    
    oldTargetPin - the old target pin
    
    targetPin - the new target pin
  - layoutScene
```
public void layoutScene()
```
    Invokes layout of the scene.
