Remarks
Override this method in your shape class, to respond to a change of shape or location. This method will be called only if the old and new values are different. Make sure that you call OnAbsoluteBoundsChanged.
When to use this method
Use this method when you want to update values that are not in the Store – that is, they are not properties of the model or diagram elements. This method is always called after the bounding box changes, even when the user invokes the Undo command.
If you want to respond to the change by making another change inside the model or diagram – for example to adjust the position of neighboring shapes - create a ChangeRule to observe the AbsoluteBounds domain property in your shape class. In an Undo, all the in-store properties are reset by the Undo handler, and the change rule is not called. For more information, see the example in AbsoluteBoundsDomainPropertyId.
If you want to constrain the size or location of a shape, use BoundsRules.
