You don't use it - we are campaigning to get it removed because it
slows down GTK a lot and is not particularly useful.
To get notification you connect to "notify::property_name", or just
"notify" to get notification on all properties.
To see how to send notifies in your own object implementations, look
at most any GTK widget. Typically:
void
set_foo (Object *obj, Foo *foo)
{
obj->foo = foo;
g_object_notify (obj, "foo");
}
obj_set_property (blah blah)
{
case PROP_FOO:
set_foo (obj, g_value_get_foo (value));
break;
}
