Thanks to everyone who helped on the 64-bit internal ID question I posted. I end up maintaining a copy of index-and-id mapping to work around it.
Now I have a question on how to properly update the model. My model is a read-only representation of a database. I am using a QTreeView to hold the model. The data themselves are not tree-like but I like the visual of QTreeView better. The model needs to update itself periodically from the remote database. I keep a QList of data IDs and rebuild the list every time I get a new snapshot from the database. What's the recommended way to reflect the changes to the view? I need to keep the current selection and scroll position of the QTreeView between updates. Do I reset the model? Or do I remove deleted rows and insert new ones? Thanks. _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
