Help with writing dynamic menus in gnome panel applets

[dbaker 0bits com]

Hi all,

I'm trying in vain to finish the last bit of my applet but can't seem to 
figure it out. Rather than spending more time reading i thought i may 
short circuit the learning process and ask for help.

I fundamentally need to build a dynamic menu on the panel. This i've 
done and it comes up fine and i can click on items and correct actions 
happen. I've also read the 'writing panel applets' tutorial, but what 
i'm requiring is not covered.

So what i currently have is a menu like below that appears in the panel 
when i right click on my applet icon.

+-------------------+
|      AAAAA        |
+-------------------+
|      BBBBB        |
|      CCCCC        |
+-------------------+
| Remove from Panel |
|       Move        |
+-------------------+
|   Lock to Panel   |
+-------------------+

The items AAAAA, BBBBB and CCCCC are created by me and the rest are the 
default panel items.

Now i need to programatically add new menu items at a specific location 
in the menu, like just after AAAAA and before BBBBB. If i use

  bonobo_ui_component_set_translate(uic, "/popups/popup", xml, ev);

it always *appends* to my previously crated items and appears after the 
CCCCC menu item.

So how do i add an item at a specific index in the menu ? Do i need to 
rebuild the complete menu xml every time by doing a thaw() and then 
bonobo_ui_component_rm() followed by a bonobo_ui_component_set_translate() ?

Am i missing something ?
Thanks
Dave
