Yes, call that first, something along these lines:
/* chain up to constructor of parent class */
object = G_OBJECT_CLASS (myobject_parent_class)->
constructor (type, n_construct_properties, construct_params);
myobject = MYOBJECT (object);
The variable saving the parent class is at the toplevel of the file:
static GObjectClass *myobject_parent_class = NULL;
And you'll have saved the parent class in the class init function:
myobject_parent_class = g_type_class_peek_parent (klass);
