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:

• addObject
• addObjectAt
• removeObject
• removeObjectAt

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:

• IlvAttachmentLayout
• IlvCardLayout
• IlvCenteredLayout
• IlvStackerLayout

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.

  // Creates the composite graphic
  IlvCompositeGraphic composite = new IlvCompositeGraphic();

  // Sets the layout style
  IlvAttachmentLayout layout = new IlvAttachmentLayout();
  composite.setLayout(layout);

  // Adds 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");

  // Adds the graphic object to the graphics tree
  composite.setChildren(1, text);

  // Sets 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 Rogue Wave JViews Prototypes and should not be used inside a prototype.

Since:

JViews 6.0

A new composite graphic 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(boolean withParent)

Invalidates this IlvCompositeGraphic. This composite graphic and, optionally, all parents above it are marked as needing to be laid out.

Parameters:

withParent - Whether the parent gets invalidated as well.

Since:

JViews 8.5

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 be called whenever the bounding box is changed, even if this change does not require a new layout 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 when writing a subclass. 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

invalidateBBoxCache

protected void invalidateBBoxCache()

Invalidate the bounding box cache.

Overrides:

invalidateBBoxCache in class IlvGraphicSet

Since:

JViews 8.5

validate

moveResize

public void moveResize(IlvRect size)

Moves and resizes the object. The way the bounding box of this object is modified depends on the transformation mode, the resizing policy and the layout.
If the layout does not permit resizing the first child only (that is, IlvCardLayout and IlvStackerLayout), or if the transformation mode is TransformationModeAll, it resizes all elements of the composite graphic uniformly so that the attachment bounds of the composite graphic is the input size.
If the layout does permit resizing the first child only (that is, IlvAttachmentLayout and IlvCenteredLayout), and the transformation mode is TransformationModeBaseOnly, it resizes only the base element (child 0) and it respects the resizing policy. If the resizing policy is ResizingBase, the input size defines the new size of the base. If the resizing policy is ResizingComposite, the input size defines the new size of the entire composite graphic.
This method calls the applyTransform method.

Overrides:

moveResize in class IlvGraphic

Parameters:

size - The new bounding rectangle of this object.

See Also:

IlvLayoutManager.resizeFirstChildOnly(), setResizingPolicy(int), setTransformationMode(int), ResizingBase, ResizingComposite

resize

public void resize(double neww,
                   double newh)

Resizes this object. The way the bounding box of this object is modified depends on the transformation mode, the resizing policy and the layout.
If the layout does not permit resizing the first child only (that is, IlvCardLayout and IlvStackerLayout), or if the transformation mode is TransformationModeAll, it resizes all elements of the composite graphic uniformly so that the attachment bounds of the composite graphic are (neww, newh).
If the layout does permit resizing the first child only (that is, IlvAttachmentLayout and IlvCenteredLayout), and the transformation mode is TransformationModeBaseOnly, it resizes only the base element (child 0) and it respects the resizing policy. If the resizing policy is ResizingBase, the input size (neww, newh) is the new size of the base. If the resizing policy is ResizingComposite, the input size (neww, newh) is the new size of the entire composite graphic.
This method calls the applyTransform method.

Overrides:

resize in class IlvGraphic

Parameters:

neww - The new horizontal width.

newh - The new horizontal height.

setSensitive

public void setSensitive(boolean sensitive)

When this property is set to true, the object interactor IlvCompositeInteractor dispatches the AWT events to the Swing actions defined in the event maps.

Since:

JViews 8.0

IlvCompositeInteractor, setEventMap(IlvEventMap), setEventMaps(int, IlvEventMap)

isSensitive

public boolean isSensitive()

When returns true, the AWT events are dispatched to the Swing actions defined in the event maps.

Specified by:

isSensitive in interface IlvComposite

setJViews80BoundingBoxCompatibility

public static void setJViews80BoundingBoxCompatibility(boolean enable)

Enables or disables the compatibility mode how the bounding box of composite graphic objects are treated. In JViews 8.0 and earlier, the bounding box of the composite graphic object did not include the children that are in different layers. This is very inconvenient when handling children layers and makes it sometimes impossible to have a child which itself is a composite graphic object but uses layers.

Since JViews 8.1, the bounding box of the composite graphic object includes all visible children independent from their layer specification. Switching layers of children does not modify the bounding box anymore and hence the layer treatment is more easy.

By default, the compatibility is disabled (i.e. the new mode is enabled).

Since:

JViews 8.1

isJViews80BoundingBoxCompatibility

public static boolean isJViews80BoundingBoxCompatibility()

Returns whether the compatibility mode how the bounding box of composite graphic objects are treated.

Since:

JViews 8.1

isBaseTextDirectionSensitive

public boolean isBaseTextDirectionSensitive()

Returns true because the bounding boxes of object's children may depend on its text direction. This method overrides the isBaseTextDirectionSensitive method of the class IlvGraphic.

Overrides:

isBaseTextDirectionSensitive in class IlvGraphicSet

Returns:

true

baseTextDirectionChanged

public void baseTextDirectionChanged(int oldBaseTextDirection,
                                     int newBaseTextDirection)

Called when the object is base text direction sensitive and the resolved base text direction has changed.

Overrides:

baseTextDirectionChanged in class IlvGraphicSet

Parameters:

oldBaseTextDirection - Resolved base text direction of this object before the change.

newBaseTextDirection - Resolved base text direction of this object after the change.

Since:

JViews 8.8

isBaseTextDirectionSensitive()

componentOrientationChanged

public void componentOrientationChanged(ComponentOrientation oldOri,
                                        ComponentOrientation newOri)

Called when the object is component orientation sensitive and the component orientation has changed.

Overrides:

componentOrientationChanged in class IlvGraphicSet

Parameters:

oldOri - Orientation of this object before the orientation change.

newOri - Orientation of this object after the orientation change.

Since:

JViews 8.8
