```
public class IlvGraphicSet
extends IlvBidiGraphic
implements IlvGraphicBag, GraphicBagHierarchyEventReceiver, ManagerViewsHierarchyEventReceiver
```
An IlvGraphicSet instance is used to group several graphic objects together.
For an IlvGraphicSet object contained inside an IlvGraphicBag instance (for instance inside IlvManager, the following methods must be called from the applyToObject method of the IlvGraphicBag instance holding this IlvGraphicSet object.
- applyTransform
- setVisible
Example

The following code example shows how to use IlvGraphicSet in a simple Java application:
```
  IlvManager manager = new IlvManager();
      
  IlvGraphicSet graphicSet = new IlvGraphicSet();
  // Set an object interactor that makes the graphic objects sensitive to events.
  graphicSet.setObjectInteractor(new IlvGraphicSet.DelegateObjectInteractor());

  // Create the graphic objects and add them to the graphic set.
  IlvReliefRectangle border = new IlvReliefRectangle(new IlvRect(10,10,60,90));
  border.setBackground(new Color(228,225,224));
  graphicSet.addObject(border, false);
  
  IlvText label1 = new IlvText(new IlvPoint(27,40), "ILOG");
  Font font = new Font(label1.getFont().getName(), Font.BOLD,
                       label1.getFont().getSize());
  label1.setFont(font);
  graphicSet.addObject(label1, false);
  
  IlvText label2 = new IlvText(new IlvPoint(20,60), "JViews");
  label2.setFont(font);
  graphicSet.addObject(label2, false);
  
  // Add the graphic set containing all the graphic objects to the manager.
  manager.addObject(graphicSet, true);
 
```
The following image shows the graphic objects created in the code example:

The following code example shows how to remove an object from the graphic set, even when the graphic set is already inside a manager:
```
 graphicSet.removeObject(label2, false);
 
```
About Graphic Objects

IlvGraphicSet is a custom graphic object, that is, a subclass of IlvGraphic. Graphic objects are controlled using an instance of IlvManager or one of its subclasses, and displayed using one or more IlvManagerView instances in a Java Swing application. For information about generic features for graphic objects, see IlvGraphic.

public void draw(Graphics dst,
                 IlvTransformer t)
```
    Draws the object. This method simply calls the draw methods of contained objects. Objects not in the clip area are not drawn.
    
    Specified by:
    
    draw in class IlvGraphic
    
    Parameters:
    
    dst - The destination Graphics.

protected void drawCore(Graphics2D dst,
                        IlvTransformer t)
```
    Draws the object. This method is called from draw(java.awt.Graphics, ilog.views.IlvTransformer) after processing the alpha transparency. It can be overridden in subclasses.
    
    Parameters:
    
    dst - The destination Graphics.

```
public void applyTransform(IlvTransformer t)
```
    Applies a transformation to the shape of contained objects.
    Note that a call to this method can modify the bounding box of the graphic set. For this reason, if the graphic set is contained inside an IlvManager, this method can be called only using the method IlvManager.applyToObject(ilog.views.IlvGraphic, ilog.views.IlvApplyObject, java.lang.Object, boolean) of the manager.
    
    Specified by:
    
    applyTransform in class IlvGraphic

  - getIntersectionWithOutline
```
public IlvPoint getIntersectionWithOutline(IlvPoint innerPoint,
                                           IlvPoint outerPoint,
                                           IlvTransformer t)
```
    Returns the intersection of the line segment from inner point to outer point with the shape of the graphic object. This method is used the clip links against the shape of the node. The implementation of this method must be robust with respect to the input points: Even if innerPoint is not inside the graphic object, or if outerPoint is not outside the graphic object, it must return a valid point. For instance, if there is no intersection, it can return the start point.
    This implementation works well if no clip is set on this object, by choosing the best intersection with a subobject contained in the graphic set. If a clip is set on the object, it checks whether this intersection is inside the clip area. If it is outside the clip area, it returns the intersection with the clip area. This works well only if subobjects are not entirely outside the clip area.
    
    Overrides:
    
    getIntersectionWithOutline in class IlvGraphic
    
    Parameters:
    
    innerPoint - A point usually inside the graphic object, given in manager view coordinates.
    
    outerPoint - A point usually outside of the graphic object, given in manager view coordinates.
    
    t - The transformation used to draw the object.

```
public void write(IlvOutputStream stream)
           throws IOException
```
    Writes the object to an IlvOutputStream. You should not call this method directly; instead, you should use the write methods of the manager.
    
    Specified by:
    
    write in interface IlvPersistentObject
    
    Overrides:
    
    write in class IlvGraphic

```
public String getToolTipText(IlvPoint p,
                             IlvTransformer t)
```
    Returns the tooltip text to display when the mouse pointer is at a specified location inside the graphic object. It tries to retrieve the tooltip from one of the elements in this graphic set. If this fails, it tries to retrieve the tooltip of the entire graphic set.
    Note that you must enable the tooltip mechanism for the manager view by calling the static method IlvToolTipManager.registerView(ilog.views.IlvManagerView).
    
    Overrides:
    
    getToolTipText in class IlvGraphic
    
    Parameters:
    
    p - The location of the mouse (in view coordinates).
    
    t - The transformer that converts the coordinate system of this object (the manager coordinates) into the coordinate system of the manager view in which the tooltip is about to be displayed (the view coordinates).
    
    Returns:
    
    The tooltip at point p for transformation t, or null if no tooltip should be displayed.

```
    Returns the Swing pop-up menu to display when the pop-up is triggered while the mouse pointer is at a specified location inside the graphic object. It tries to retrieve the pop-up menu from one of the elements in this graphic set. If this fails, it tries to retrieve the pop-up menu of the entire graphic set.
    Note that you must enable the pop-up menu mechanism for the manager view by calling the static method IlvPopupMenuManager.registerView(ilog.views.IlvManagerView).
    
    Overrides:
    
    getPopupMenu in class IlvGraphic
    
    Parameters:
    
    p - The location of the mouse (in view coordinates).
