There are several related questions, but I found none that really answered this detail:

Where is the reference to the current icon theme stored?

Since the icon theme can be changed, hence so too the path to its folder, it must be stored somewhere. I'm making an application and I want it to draw its own icons from the icon theme currently in use. I've seen answers showing how to retrieve the path using Python and Gtk, but I am using PyQt and would like to avoid importing Gtk as well.

Is there a configuration file somewhere holding the current icon theme's name or path? Or do you know a PyQt means to do that?

A reference to the current icon theme can be found in gconf-editor at:

desktop > gnome > interface > icon_theme

enter image description here

You can alternatively read directly ~/.gconf/desktop/gnome/interface$ cat %gconf.xml file.

Unfortunately, this does not provide a path to the relevant icon theme. I'll check how this setting relates to the path and i'll let you know ;-)

Yes it's interesting. Especially in your case---Faenza Darkest---which in and of itself is incomplete and takes most of its icons from the main Faenza theme. – Benjamin Aug 21 '11 at 22:32
My case is not the best example, cause i've installed gnome3 and my system is currently mixed with gconf and dconf settings...but anyways.. – Pavlos G. Aug 22 '11 at 10:19

Have a look at PyXDG (package python-xdg in Ubuntu). xdg.IconTheme.getIconPath(iconname) gets you the path to the give icon.

This doesn't give me the icon of the current theme. If I take the result of IconTheme.getIconPath('anki'), it returns /usr/share/pixmaps/anki.xpm which is incorrect since the current theme is 'Faenza' and the corresponding file for Anki is at ~/.icons/Faenza/Apps/. The Anki desktop file does not specify this pixmaps path either. – Benjamin Aug 21 '11 at 22:42

This looks too easy, so I'm probably missing something here... but what about:

icon = QIcon.fromTheme("firefox")

QT is supposed to take care of this itself.

Thanks. Indeed, According to the doc, it should work :) I'll try that. – Benjamin Aug 22 '11 at 7:33
