Re: the directory for current theme used by Gtk

[Christoph Reiter <reiter christoph gmail com>]

I use the following to get a list of available themes, maybe it's useful:

    import os
    import gi
    gi.require_version("Gtk", "3.0")
    from gi.repository import Gtk, Gio

    def get_themes():
        theme_dir = Gtk.rc_get_theme_dir()
        theme_dirs = [theme_dir, os.path.join(os.path.expanduser("~"),
".themes")]

        themes = set()
        for theme_dir in theme_dirs:
            try:
                subdirs = os.listdir(theme_dir)
            except OSError:
                continue
            for dir_ in subdirs:
                gtk_dir = os.path.join(theme_dir, dir_, "gtk-3.0")
                if os.path.isdir(gtk_dir):
                    themes.add(dir_)

        try:
            resource_themes = Gio.resources_enumerate_children(
                "/org/gtk/libgtk/theme", 0)
        except GLib.GError:
            pass
        else:
            themes.update([t.rstrip("/") for t in resource_themes])

        return themes
