      If you create a QTreeWidget with setDragDropMode(QAbstractItemView::InternalMove) and setSelectionMode(QAbstractitemView::ExtendedSelection) and drag multiple items at the same time, when you drop them their order will be reversed.

      I believe that replacing the calls to takeFirst() with takeLast() at the end of void QTreeWidget::dropEvent(QDropEvent *event) in qtreewidget.cpp may fix this but I haven't tried it myself.

      I can write a sample application that demonstrates this if you're not able to reproduce the bug.
