      extended by ilog.views.graphic.IlvGraphicSet
          extended by ilog.views.graphic.composite.IlvCompositeGraphic
All Implemented Interfaces:

public class IlvCompositeGraphic
extends IlvGraphicSet
implements IlvComposite, IlvAttachmentBounds, ManagerSelectionListener, IlvHotSpot, IlvDefinitionRectInterface

IlvCompositeGraphic stores and controls the layout of multiple IlvGraphic objects thus building complex graphic objects.

Child Graphic Objects

An IlvCompositeGraphic instance holds a collection of IlvGraphic objects organized into a tree structure. The first child, returned by calling getChildren(0), is called the base of the composite graphic object. Call setChildren to add or remove children.

Note: the following methods inherited from IlvGraphicSet should not be called directly:

Layout and Attachment Rules

A composite graphic object is made of child graphics and a layout manager object. Unlike graphic sets, composite graphics have the capability to control the layout and attachment of the child objects. Graphic objects in a composite graphic instance can be distributed across several layers. Their layout is controlled by an IlvLayoutManager instance. Possible layout styles are as follows:

The following code example shows how to set the layout style for the composite graphic object and how to add the base of the composite graphic. 

  // Create the composite graphic
  IlvCompositeGraphic composite = new IlvCompositeGraphic();
  
  // Set the layout style
  IlvAttachmentLayout layout = new IlvAttachmentLayout();
  composite.setLayout(layout);
  
  // Add the base graphic object to the composite graphic
  IlvRectangle rectangle = new IlvRectangle(new IlvRect(100, 100, 40, 40), true, true);
  composite.setChildren(0, rectangle);

You use attachment rules to set the position of child graphic objects in comparison to the base object. 

  IlvText text = new IlvText();
  text.setLabel("Composite Graphic");
  
  // Add the graphic object to the graphics tree
  composite.setChildren(1, text);
  
  // Set the position of the object at place 1 in the graphics
  // tree relative to the base object. In this case, the top center point of 
  // the IlvText object is aligned with the bottom center of the base 
  // IlvRectangle object.
  
  composite.setConstraints(1, 
         new IlvAttachmentConstraint(
                 IlvAttachmentLocation.TopCenter,
                 IlvAttachmentLocation.BottomCenter));

About Graphic Objects

IlvCompositeGraphic 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.

Limitation: IlvCompositeGraphic is not compatible with ILOG JViews Prototypes and should not be used inside a prototype.

Since:
JViews 6.0

Method Detail

copy

public IlvGraphic copy()
Returns a copy of this composite node.

Overrides:
copy in class IlvGraphicSet
Returns:
A new composite node that is a copy of this one.
See Also:
IlvGraphic

isValid

public boolean isValid()
Returns true when this object needs to be rebuilt.

Specified by:
isValid in interface IlvComposite

invalidate

public void invalidate()
Invalidates this IlvCompositeGraphic. This composite graphic and all parents above it are marked as needing to be laid out.

This method must also be called whenever bounding box is changed, even if this change does not require a relayout of the decorations.

Note that this method is automatically called when a change occurs for this composite graphic. It only needs to be called directly in special cases such as writing subclassing. For instance, the default implementation of moveResize(IlvRect) performs the invalidation. Hence, if this method is overridden without calling super.moveResize, invalidate must be called explicitly.

Specified by:
invalidate in interface IlvComposite

validate

public void validate()
Ensures that this component has a valid layout.

setLayout

public void setLayout(IlvLayoutManager layout)
Sets the layout manager for this composite graphic.

Parameters:
layout - the specified layout manager
See Also:
getLayout()

getLayout

public IlvLayoutManager getLayout()
Returns the layout manager for this composite graphic.

See Also:
setLayout(ilog.views.graphic.composite.layout.IlvLayoutManager)

setChildren

public void setChildren(IlvGraphic[] children)
Sets a new collection of children for this object. Note that a call to this method can modify the bounding box of this object. 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.

Parameters:
children - Array of children to be added. The value null removes all the children.

setChildren

public void setChildren(int index,
                        IlvGraphic child)
Removes the current child at the supplied position if any, and adds the given child to this object at the supplied position. Note that a call to this method can modify the bounding box of this object. 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.

Parameters:
index - The position of the child to be set.
child - The child to be added. The value null removes the current child at the supplied position.

getChildren

public IlvGraphic getChildren(int index)
Returns the child at the supplied position.

Specified by:
getChildren in interface IlvComposite
Parameters:
index - The position of the child to return.

resize

public void resize(float neww,
                   float newh)
Resizes this object. The way the bounding box of this object is modified depends on the resizingPolicy.
If the resizingPolicy is ResizingComposite, it sets its new size as (neww, newh).
If the resizingPolicy is ResizingBase, it sets the size of the base as (neww, newh). This method calls the applyTransform method.
