If you use GObject properties for these attributes, you can call
g_object_class_list_properties (); That will return an array of
GParamSpec* pointers, which describe all the properties installed in
that object's class. If your objects implement any GInterfaces which
install properties (A 2.3/2.4 feature), you should also use
g_object_interface_list_properties(); The return values of both these
functions should be freed with g_free();

Getting the value of the property can be done via
g_object_get/g_value_get_valist.
