G'day, It has been my impression that the gnome-panel's main menu is based on info in files in /usr/share/applications. However there are items in my menus (for example, other/kate and other/kwrite) without files and there are files without entries (for example, virtualbox.desktop).
I've tried 'killall gnome-panel' to force a restart and, hopefully, rebuild the menu tree. The panel did restart, but the menus didn't update and my icons for editor, mail, and browser were b0rked -- not what I wanted! Also, looking in ebuilds I've found menu and desktop related directives, like "make_desktop_entry ..." and "doins ... desktop", but sometimes /usr/share/applications doesn't have a corresponding entry. Can somebody please explain how the gnome main menu is built, where it resides, and how to force a rebuild? Thanks. David
