Description
Returns a sequence Dispatch IDs of the ambient properties that the control application would like to be notified of changes to. This notification consists of the container calling OLE-part-set-ambient-property upon a change to any of the ambient properties in the sequence.
The default method returns an empty sequence. If you would like to be notified of changes to particular ambient properties, define a method on this function to return a sequence containing the Dispatch IDs for those properties.
If you are defining a method on a subclass of <DUIM-OCX>, page 169 (that is, when using the DUIM-OLE-Control library), use union to merge your values with those returned by next-method.
