Warning
gtk_object_weakref is deprecated and should not be used in newly-written code. Use g_object_weak_ref() instead.
Adds a weak reference callback to an object. Weak references are used for notification when an object is
finalized. They are called "weak references" because they allow you to safely
hold a pointer to an object without calling g_object_ref() (g_object_ref() adds
a strong reference, that is, forces the object to stay alive).
