I don't experiment this problem. Sqlkit is based on treeview that load and display data from a database table. The model has classes arranged by sqlalchemy and each cell renderer picks data from that object to represent it via a cell_data_func. I display foreign key picking data from the related table so that loading data is somehow slowed down (2-10 seconds for 10.000 records depending on foreign keys). Destroying this table is done almost immediately, you don't perceive any significant delay. I'm testing it on Ubuntu 10.04 running on a notebook 1.8 GHz centrino. sandro -- Sandro Dentella *:-) http://www.reteisi.org Soluzioni libere per le scuole http://sqlkit.argolinux.org SQLkit home page - PyGTK/python/sqlalchemy _______________________________________________ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
