ok finally i have find one solution, and one website is very useful to understand this: http://www.frankrock74.it/frankrock74/?p=1738
i do something like this:
open alacarte and made my personal menu "Script" as an empty menu.I can put this in any menu but i choose Application.
Now i create my personal .desktop file as is for example.:
#!/usr/bin/env xdg-open
[Desktop Entry]
Version=1.0
Type=Application
Terminal=false
Exec= /home/$USER/myscript/script.sh
Name=script1
Icon=/home/$USER/image/icon.png
Categories=Script
Now is important to made one modification inside a file:
Terminal: gedit ~/.config/menus/applications.menu
in this file is possible to view the desktop directories created with alacarte,
example:
<Name>alacarte-made-1</Name>
<Directory>alacarte-made-1.directory</Directory>
this second voice is the menù i have created "Script"
to make the launchers functionally inside this desktop.directory
is necessary to add this line after the upper voice.
A directive to the menu to include our category
As is:
<Include>
<And>
<Category>Script</Category>
</And>
</Include>
in finally we have somthing like this:
<Name>alacarte-made-1</Name>
<Directory>alacarte-made-1.directory</Directory>
<Include>
<And>
<Category>Music</Category>
</And>
</Include>
NOw saved and finally any my.desktop files i put inside the folder:
~/.local/share/applications/
is recognized in my personal menù and works well.
Is a good choice to read this web site to understanding desktop directories:
http://library.gnome.org/admin/system-admin-guide/stable/menustructure-desktopentry.html.en
hoping my english is comprensible.
