Thread Subject: Setting uicontrol callbacks outside of the main gui .m file

I have a dynamic GUI that creates/destroys components at
runtime. I have written a class in a separate file to create
and set the properties of new uicontrols. I'm trying to set
the callbacks for the uicontrol, but I am having trouble
setting the callback function, which is located in the main
gui file, similar to a GUIDE .m file, where other callbacks
(for static uicontrols) are generated automatically.

Imagine this: I have a class 'myclass' that contains the
necessary information to generate some uicontrols. I also
have the main gui.m file that initializes the gui, and
passes a parent panel to a member function of myclass. The
member function generates some children uicontrols, modifies
their properties, assigns them to the parent panel, and
returns control to gui.m. Everything works except assigning
a callback, since the callback is located in the GUI file.

So my question is this: can it be done? What are some
suggestions for syntax to do this? Must I somehow specify
where the callback function is located?

Any ideas? I'm still lost on this one.

In order for a routine to set a function as a callback to a control,
the function must be the main file of a .m file on the path,
or the routine setting the callback must -somehow- have obtained
a handle to the function. It is not possible for B.m to set sub-function
Z of A.m as a callback unless B has access to a handle to Z.
