How does GPermission work?

Question

GPermission seems to have little to no documentation. How do you actually use it? (I'm currently using it for a GTK LockButton).

Answer 1

I agree, the documentation is pretty lacking. GPermission is an abstract base class which isn't particularly useful by itself. You need something which actually implements GPermission, like polkit.

There are some examples in gnome-control-center, like the datetime panel.

Answer 2

Google found me this straight away: https://developer.gnome.org/gio/2.26/GPermission.html

Is that not sufficient?

Answer 3

You need to subclass GPermission. When you need to change the values, you call g_permission_impl_update. Very non-intuitive, but yeah that's how it's done.
