How to get the icon for a MIME type?
I don't want to use
g_file_info_get_icon() because its input parameter is a file, not a MIME type.
My use case:
I have a wrapper file which embeds a media object, I can get the MIME type of the media object and want to find the icon of the MIME type. And I don't want to dump the media object to a separate file to use
