OpenGadgetList() from a different program?

[GBeebe]

... What I'm trying to do is have a program call a library and pass the GadgetID of a container gadget to a ProcedureDLL in it. What I want the library to do is add other gadgets to the container gadget. Basically to add "plug-in" functionality to later extend the program's capabilities. But OpenGadgetList() doesn't appear to recognize gadgetID's outside of its own program. Does anyone know if this can be done? And if so, can the library monitor the events of the gadgets that it created?
