You might be interested in knowing that the current development branch
of Octave has changed nested functions:

Thanks. Even though I mentioned nested functions, I am not currently using any. My code is structured as follows:

- Main GUI function

  - Sub-function to create the UI controls

  - Sub-function for first callback

  - Sub-function for second callback

  - etc...

end

I just need to find a mechanism to pass (and modify) data to/from the callback functions to the main GUI function where the information is stored (in a struct).

It's good to know about nested functions though, I'll give them a try when I upgrade to the next stable release of Octave (hopefully there will have some improvement to the Octave GUI by then, fingers crossed). Right now, I need a solution for 3.6.2. I have tried defining the callback as a cell array, i.e. address@hidden,gui,k} or even address@hidden,"gui","k"}, but that didn't work either.

Using a cell array is the right approach. It is supported. What error do you get and what code are you using? Also please note that a GUI callback always get the object handle and an event data as first 2 arguments. Whatever arguments you specify in the cell array starts at position 3 in the callback argument list.
