Hi,
I have a treeView using a custom model. I want to sort on certain levels of the tree. For example, lets say level 1 is fruits, level 2 is apples, and level 3 is types of apples. I want to skip sorting on level 3 (types of apples). My level 3 has a lot of items and it causes a decent pause when Qt tries to sort them. Is this possible? How would you do it? I'm using QSortFilterProxyModel, but re-implementing lessThan doesn't help because the sort still goes through all the items. Using QT4.4. Thanks.
