Class IltFacesObjectSelectActionListener

java.lang.Object
  ilog.tgo.faces.graph.dhtml.event.IltFacesObjectSelectActionListener

All Implemented Interfaces:

ServerActionListener, EventListener

public class IltFacesObjectSelectActionListener
extends Object
implements ServerActionListener

This class implements a server action listener that is invoked by the clientSelectInteractor tag to process object selection and actions.

By default this listener will check for the supported object actions. If no actions are supported, it will perform regular single or multiple selection. The supported object actions are:

• expand subnetworks
• collapse subnetworks
• expand information icons
• collapse information windows
• expand system icons
• collapse system windows

The default object action behavior is implemented by the IltFacesDefaultObjectAction.performObjectAction(IlpGraphView, int, int) method.

The user may override or extend the object action behavior by setting a method binding to the objectActionMethodBinding tag attribute of the clientSelectInteractor tag. The method binding should have the following signature:

 boolean method_name(IlpGraphView view, int xPos, int yPos)
 

Where:

• method_name is the method name
• view is the graph view containing the object
• xPos is the x component of the clicked point
• yPos is the y component of the clicked point

If the method returns true, no selection will be processed and a new image will be generated.
