Re: Associate an icon and an application to a mime type

It depends of what support you want to get. 

For example, to associate application with the mime type you should add
field 

MimeType=application/you-mime-type

to desktop file of your application which is installed
in /usr/share/applications.

To get support older gnome you should also install three files
- .applications, .keys, .mime, but this is gone since gnome 2.4.

To associate icon with mime type you should just install that icon with
default icon theme somewhere in /usr/share/icons/. This is more
complicated work, not many application does it, many just use gnome-
icon-theme, which contains icons.

Anyway there is a lot of examples of how to do it. Try any gnome
program, file-roller for example.
