[Ubuntu] Modify the "Main Menu" item panel in Ubuntu

when using Ubuntu, we can add a "Main Menu" item to the panel

 

Where to add / modify the menu items? Here we go!

 

In fact that the items of Main Menu are stored under /usr/share/applications , here we will try to add a laucher of eclipse for example.

sudo vim /usr/share/applications/eclipse.desktop

 

In the file, add these code:

[Desktop Entry]
Name=Eclipse
Comment=c project manage software
Exec=/opt/eclipse/eclipse
Icon=/opt/eclipse/icon.xpm
Terminal=false
Type=Application
Categories=GNOME;GTK;Office;Eclipse;

 

Then you will see the icon under the Office now!
