Method
GObjectObjectweak_ref
Declaration [src]
void
g_object_weak_ref (
  GObject* object,
  GWeakNotify notify,
  gpointer data
)
Description [src]
Adds a weak reference callback to an object. Weak references are
used for notification when an object is disposed. 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).
Note that the weak references created by this method are not
thread-safe: they cannot safely be used in one thread if the
object’s last g_object_unref() might happen in another thread. Use GWeakRef if thread-safety is required.
This method is not directly available to language bindings.
Parameters
- notify
- 
            Type: GWeakNotifyCallback to invoke before the object is freed. 
- data
- 
            Type: gpointerExtra data to pass to notify. The argument can be NULL.The data is owned by the caller of the method.
