MgGraphItem; guint mg_graph_item_get_type (void); GObject* mg_graph_item_new (MgConf *conf, MgBase *ref_obj); MgBase* mg_graph_item_get_ref_object (MgGraphItem *item); void mg_graph_item_set_position (MgGraphItem *item, gdouble x, gdouble y); void mg_graph_item_get_position (MgGraphItem *item, gdouble *x, gdouble *y);
Each graph item which needs to have its position kept in the MgConf object (and written in the dictionnary file) has a corresponding MgGraphItem object. A graph item can hold a reference to any MgBase object, meaning that the position it stores is the position where the references object's graphical representation will be on the canvas.
GObject* mg_graph_item_new (MgConf *conf, MgBase *ref_obj);
Creates a new MgGraphItem object
MgBase* mg_graph_item_get_ref_object (MgGraphItem *item);
Get the referenced MgBase object, if it exists.
