Me too :) If you're interested in some nice Gtk2-Perl objects that automate this sort of thing, check out my projects: Gtk2::Ex::DBI, Gtk2::Ex::Datasheet::DBI ( and PDF::ReportWriter for reports ). They're available on my website, http://entropy.homelinux.org/axis ... but unfortunately there's no power to our apartment at the moment ( damned thing caught on fire ), so you'll have to wait about 12 hours until the power comes back up and I boot up the server. > The data model often changes drastically, a lot of rows and > subtrees are modified, deleted, created, etc. If you change the model significantly, you want to do one of 2 things. Option 1 ) Create a new model, populate it, and then use gtk_tree_view_set_model to tell the treeview about the new model, and dump the old one. Option 2 ) use gtk_tree_view_set_model to point the treeview at another ( empty ) model ( or maybe NO model ... I'm not sure if you can do this, I've never tried it ). Then do your changes to the real model. Then use gtk_tree_view_set_model once more to point the treeview back at the real model. The idea with both of these approaches is that when you do lots of changes to the model, it forces the treeview to keep updating, and this is slow. It's best to do all your changes with the treeview *disconnected* from the model, and then connect it back. Works for me anyway. -- Daniel Kasak IT Developer NUS Consulting Group Level 5, 77 Pacific Highway North Sydney, NSW, Australia 2060 T: (+61) 2 9922-7676 / F: (+61) 2 9922 7989 email: dkasak@xxxxxxxxxxxxxxxxxxxx website: http://www.nusconsulting.com.au _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
