emacsclient not integrated into modern window systems

[Rusi]

Student of mine asked me if its possible to have emacs open from the file 
browser. [By default it opens with gedit]
For 1/2 hour we tried to find properties/open-with etc to make it emacsclient
but to no avail

After a lot of struggle the best I came up with was the below steps.
So... If installing emacs (using say apt) makes emacs an established app to open
(some) mimetypes, why is emacsclient not setup similarly?

[I realize that this question may be more suitable for ubuntu/gnome/ etc 
folks...
Still thought I'd ask]

-------------------------
0. Put (server-start) into init.el
   Check that now 'emacsclient somefile' from a shell starts the same emacs

1. Put the following (between the --------- and ------------- )
into the file ~/.local/share/applications/emacs.desktop
---------
[Desktop Entry]
Name=EmacsClient
GenericName=Text Editor
Comment=Edit text
MimeType=text/english;text/plain;text/x-makefile;text/x-c++hdr;text/x-c++src;text/x-chdr;text/x-csrc;text/x-java;text/x-moc;text/x-pascal;text/x-tcl;text/x-tex;application/x-shellscript;text/x-c;text/x-c++;
Exec=emacsclient -n -a emacs %F
Icon=emacs
Type=Application
Terminal=false
Categories=Development;TextEditor;
StartupWMClass=Emacs
---------

2. Now in file browser, click on a file you want opened in emacs and
click properties -> open-with
Here you should find 'EmacsClient' somewhere down.
You can make it default

Note: Between 1 and 2 you may need to reboot (actually logout of X-windows is 
enough)
