Screenlet-name is shown in global menu

Is there a way to exclude application from global menu like there is possibility to hide applications from taskbar or task switcher using extended window manager hints (EWMH)?

Here is a screenshot for people who don't exactly know what is meant. (look at the upper left)

If you move focus on screenlet, the filename of is shown in application menu. If you click on empty desktop, the filename disappears.

I am having this issue as well, if I deleted file from my DESKTOP, I focus on screenlet thank, its really annoying as you have double click on desktop, a filename to dissapear

I think this blog post might include a way to fix this:
http://www.webupd8.org/2011/03/disable-appmenu-global-menu-in-ubuntu.html

It includes a way how to disable the appmenu for a single application that should be usable.

OK sorry tried to apply this. Turns out it just affects the menu displayed not the name so no fix here.

Actually, displaying a name of screenlet in the application menu is intended behaviour in Ubuntu Natty. Maybe what should be displayed shouldn't be "WhateverScreenlet.py", but just "Whatever". This can be done by providing a desktop file in /usr/share/applications or ~/.local/share/applications. In future versions of screenlets, there will be screenlet.desktop file provided with screenlets, but I believe the default value will not be empty string (to make the application menu title disappear). But this is open to discussion.

If you want to modify the behaviour yourself, you have some options:

1. Create a laucher (desktop file) and specify the name for your screenlet there (it can be left empty, maybe you have to enter one space or something). Copy it to one of the directories specified above. Log out to update desktop files or find out how to refresh desktop file database. You can also copy desktop file from ~/.config/autostart if you have screenlet in auto start list.

2. Dont want to create desktop files? Use a custom command to start a screenlet. For example "cat /usr/share/screenlets/screenlets-pack-basic/Lipik/LipikScreenlet.py | python" gives interesting results, instead of the name of screenlet, the title will contain just a dot ("."). If you like "-" instead of "." you may try "cat /usr/share/screenlets/screenlets-pack-basic/Lipik/LipikScreenlet.py | python".

3. Change the name of the python script to modify the title (it may make the screenlet not functional, but this depends on the individual screenlet itself).

I commited the new versions of screenlets into Dev PPA (https://launchpad.net/~screenlets-dev/+archive/ppa). Now the deskop files are installed and instead of "WhateverScreenlet.py" the title is "Whatever". Logging out and back in may be required to update the titles (it's probably because of the relative youth of Unity).

If you still want to disable all the titles, you have to make an effort yourself. Maybe something like...

Copy screenlets desktop files to your own desktop file directory:
mkdir -p ~/.local/share/applications/
cp -rv /usr/share/applications/screenlets/ /usr/share/applications/screenlets-pack-all/ /usr/share/applications/screenlets-pack-basic/ ~/.local/share/applications/

Change all the name fields for them:
find ~/.local/share/applications/screenlets/ ~/.local/share/applications/screenlets-pack-all/ ~/.local/share/applications/screenlets-pack-basic/ -name "*.desktop" | xargs sed -ri -e "s/(Name.*=)(.*)/\1 /g"

Delete the files from your home directory, if you don't like the changes made:
rm -rv ~/.local/share/applications/screenlets/ ~/.local/share/applications/screenlets-pack-all/ ~/.local/share/applications/screenlets-pack-basic/
