A Question On Gtk Menus

[Thomas Dineen <tdineen ix netcom com>]

Gentle People:

   A question on GTK menus. Following the examples found on the 
internet my menus
are created in the C main() function block.

   Now after block main() is successfully completed and drops into the 
function gtk_main()
is it possible or allowed to change the menus created above?

    My experiments indicate that I have been able to (outside of main):
1) Delete or append menu leaf entries.
2) Delete entire menus.

   But I have not successfully been able to append complete new menus 
and their leaf elements.

   I have an application that based on menu selections I would like to 
read some files
and create (append) entire new menus and their leaf contents.

    Also the same situation exists for Buttons is it possible to add a 
button outside of main().

   If this possible can you please post a simple example or URL pointer 
to an example.

Thanks for the help.
