Re: Link Gtk.ListStore to the real data
Swap items in your data_list in response to rows-reordered signal on the model? As for data_list, in your example you have multiple sources but the data_list is only one, so working on it makes sense. Could you try applying these suggestions to your example so we can see what doesn't work?

You mean e. g. if the first row in the view is selected then it must be the first item in the 'data_list'? In that case I have to take care about that the order of the data items is the same then in the view. This is impossible because - the view can modify the ordering based on the columns - the view use more then one data_list at the same time. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: Link Gtk.ListStore to the real data
Try a relational database. Sqlite is an easy one to use. It can sort and save data to multiple tables. Use the list model and treeview to retrieve and view the data. That way the columns can be set up dynamically along with the renderer. Use SQL to update the database.

Re: Link Gtk.ListStore to the real data
Hello. Can you make the data_list a field on your class? It's a list with
indices, right? Then, on the iter you get from your selection, use
gtk_tree_model_get_path and gtk_tree_path_get_indices. Finally get the item
from your data_list by that index.

Re: Link Gtk.ListStore to the real data
Does no one has an idea?
Am I the only one facing such problems?
