Fair enough.
The m_pLayout name is a fictive one. I was only trying to explain how to
add a menu item *when* you have a pointer to the right EV_Menu_Layout, etc.
To your question about how can you get a
EV_Menu_{Layout,ActionSet,LabelSet}, I replied saying that right now it's
*not* possible (if you're outside XAP_UnixFrame)
If you want to make it possible (and you want, belive me :) you should add
accessors to XAP_Frame (you can name it getMainMenuLayout(), or whatever).
If you're confused or you don't know how to do it, just drop me a note, I
will take a break to do that for you.
A Frame carries information about the layout and about the labelset, but not
about the actions (who are carried in the App object).

Nope. Sorry if I was not clear enough. Hope that you will be able to do
these functions (as I said, if you don't know how to do it just drop me a
note)

Entirely my fault. I was not clear enough
Sorry for the confusion
