Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`GraphDisplayListener`	`cloneWith(GraphDisplay graphDisplay)`	Makes a new GraphDisplayListener of the same type as the specific instance of this GraphDisplayListener
`void`	`dispose()`	Tells the listener that it is no longer needed and it can release any listeners/resources
`void`	`graphClosed()`	Notification that the graph window has been closed
`void`	`locationFocusChanged(AttributedVertex vertex)`	Notification that the "focused" (active) vertex has changed
`void`	`selectionChanged(java.util.Set<AttributedVertex> vertices)`	Notification that the set of selected vertices has changed

- Method Detail
  - graphClosed
```
void graphClosed()
```
    Notification that the graph window has been closed
  - selectionChanged
```
void selectionChanged(java.util.Set<AttributedVertex> vertices)
```
    Notification that the set of selected vertices has changed
    
    Parameters:
    
    vertices - the set of currently selected vertices
  - locationFocusChanged
```
void locationFocusChanged(AttributedVertex vertex)
```
    Notification that the "focused" (active) vertex has changed
    
    Parameters:
    
    vertex - the vertex that is currently "focused"
  - cloneWith
```
GraphDisplayListener cloneWith(GraphDisplay graphDisplay)
```
    Makes a new GraphDisplayListener of the same type as the specific instance of this GraphDisplayListener
    
    Parameters:
    
    graphDisplay - the new GraphDisplay the new listener will support
    
    Returns:
    
    A new instance of a GraphDisplayListener that is the same type as as the instance on which it is called
  - dispose
```
void dispose()
```
    Tells the listener that it is no longer needed and it can release any listeners/resources
