1) In GTK is there a way to delete and recreate a large menu
submenus? Ideally one would delete or replace this menu at the head and
recreate it with different entries.
2) After user selection of a menu entry, is there a way to "reset"
the menu display to the initial value displayed
when the window was created? For example when the window opens the menu
displays the value "Joe",
then the use selects "Bill" and dose a transaction. Now can we S/W reset
the menu display to "Joe"?
