| * | Add benchmark for pathological O(N^2) behavior in QQmlChangeSet. | Milian Wolff | 2016-07-18 | 1 | -0/+10 |
| This patch is just here for documentation of this behavior and does not come with a fix yet. This hotspot was found while profiling the example code attached to QTBUG-34391. It is triggered by the repeated calls to _q_itemsMoved in QQmlDelegateModel::_q_layoutChanged.
