Re: Help with writing dynamic menus in gnome panel applets

[dbaker 0bits com]

Hi Nickolay,

Thanks for your suggestions. I think that was exactly what i was looking 
for.

Just to address your concerns about useability of removing applet menu 
items, the reason is my applet will require creating, modifying and 
deletion of profiles. These profiles are listed in the panel applet and 
thus need to be removed as well as rearranged alphabetically, thus the 
requirement to delete and insert items at specific locations.

Thanks again for your pointer

Yes, you need to remove older items from the component and append new
items with set_translate.

To make things easier, you can add named placeholder with <placeholder>,
then you'll operate only on /popups/popup/removable_placeholder. For
reference please read
http://cvs.gnome.org/viewcvs/libbonoboui/doc/ui-xml.txt?rev=1.5&view=markup

And please note that removable menu items are bad thing in the usability
view, it's much better to mark unused actions as insensitive.
