Hello Roger.
I think you misunderstand the concept of callback functions. In your
example there is no appropriated callback function to deal with the changes
of spin button. And another thing, the 3rd parameters to register a
callback function must be a pointer.
I suggest to take a look at chapte
I don't now if I understood correctly your problem.
Maybe this:
gtk_window_present( GTK_WINDOW(ptr_to_your_window) );
