This raises two questions: > > 1) Is putting the icon into /usr/share/pixmap OK? Not really. That dir is obsolescent, effectively. I'm not sure if we'll ever manage to throw it away, but if you have the opportunity to control icon deployment for an app, it's really best to use the /usr/share/icons hierarchy, as it provides a lot of advantages over the 'dump a single picture in one huge directory' model. > I think I copied > this from another package, and certainly there are other applications > that have their icons there.

Yes, the icon theme specification: http://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html Basically, when you're just shipping an icon for an application, it is always going to go into hicolor. Other-named subdirectories are icon themes: if you pick an icon theme, icons from that theme's directory will be used in preference to the ones in hicolor, if they exist. Hicolor is the 'universal fallback' for icons which don't specifically exist in whatever theme the user may have chosen. So that's where you put your app's default icon. As the spec puts it: "In order to have a place for third party applications to install their icons there should always exist a theme called "hicolor" [1]. The data for the hicolor theme is available for download at: http://www.freedesktop.org/software/icon-theme/. Implementations are required to look in the "hicolor" theme if an icon was not found in the current theme." -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
