The Decorator type exposes the following members.

Constructors

	Name	Description
	Decorator(ShapeField, PointD)	Initializes a new instance of the Decorator class.
	Decorator(ShapeField, PointD, Boolean)	Constructs a new decorator.

Properties

	Name	Description
	CanMove	Whether this decorator can be moved. A decorator can be moved only if it is instantiated as moveable and also requires a host.
	DecoratorAnchorMargins	Gets the margin around the field. The decorator can attach itself to the field in this area.
	Field	Gets the field to which the decorator is assigned.
	Offset	Gets or sets the offset that modifies the default position of the decorator.
	RequiresHost	Gets the decorator and verifies whether the position between it and the shape requires a host shape.

Methods

	Name	Description
	AssociateValueWith(Store, AssociatedPropertyInfo)	Associates the decorator with a store property that is assigned to the shape.
	AssociateValueWith(Store, Guid)	Associates the decorator with a store property that is assigned to the shape.
	AssociateValueWith(Store, Guid, AssociatedPropertyInfo)	Associates the decorator with a store property that is assigned to the shape.
	AssociateVisibilityWith(Store, AssociatedPropertyInfo)	Associates the visibility of the decorator with a store property that is assigned to a shape.
	AssociateVisibilityWith(Store, Guid)	Associates the visibility of the decorator with a store property that is assigned to a shape.
	AssociateVisibilityWith(Store, Guid, AssociatedPropertyInfo)	Associates the visibility of the decorator with a store property that is assigned to a shape.
	ConfigureHostShape	Creates a host shape or configures an existing host shape.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetHostShape	Gets the host shape.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetValue	Gets the association between the decorator and a shape.
	GetVisible	Gets the visibility of the decorator that is assigned to a shape.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnAfterOffsetChanged	Enables derived classes to modify the decorator after the offset has changed.
	RepositionHostShape	Repositions the host shape and sets its visibility.
	SetValue	Sets the association with the decoration and a shape.
	SetVisible	Sets the visibility of a decorator that is assigned to a shape.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	UpdateDecoratorHostShapes(ModelElement)	Updates the bounds for the host shapes.
	UpdateDecoratorHostShapes(ModelElement, Guid)	Updates the bounds for the host shapes.
	UpdateHostShapeVisibility	Updates the visibility of the host shape.

Remarks

Decorators are wrapped around other elements in the diagram to format them.

To guarantee that inner decorators do not overlap, you should anchor them to the diagram. To anchor decorators, first override InitializeShapeFields to call the base. Then use FindShapeField to locate the shape field to which you want to apply the decorator, and then call the appropriate anchoring method.

Examples

In the following example, the Name decorator is anchored to the right side of the Name2 decorator.

partial class WizardPageShape
{
    protected override void  InitializeShapeFields(IList<Microsoft.VisualStudio.Modeling.Diagrams.ShapeField> shapeFields)
        {
            base.InitializeShapeFields(shapeFields);
            ShapeField name = ShapeElement.FindShapeField(shapeFields, "Name");
            ShapeField name2 = ShapeElement.FindShapeField(shapeFields, "Name2");
            name.AnchoringBehavior.SetLeftAnchor(name2, AnchoringBehavior.Edge.Right, 0.01);
        }
}

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
