Adding an application icon about gtk4pythontutorial HOT 1 OPEN

I might add that, in general, using importlib is the recommended pythonic way of pointing to module resources, in this case to get a path for Gtk.IconTheme.add_search_path .

Updating that example (tested on Python 3.9+), assuming your module is my_package with a subdirectory (aka PEP 420 python namespace) called icons (containing an directory tree like hicolor/scalable/apps/icon.svg):

icon_theme = Gtk.IconTheme.get_for_display(Gdk.Display.get_default())
module_spec = importlib.util.find_spec('my_package.icons')
search_locations = module_spec.submodule_search_locations if module_spec else ()
for path in search_locations:
    icon_theme.add_search_path(path)

Just don't forget to specify zip_save=False on your package metadata and add that icon package namespace to your package data.
