4 Subject: [PATCH] QTreeView: do not scroll to top if last item is removed
6 When the last item is the current item and is removed,
7 QTreeViewPrivate::updateScrollBars() is called after QTreeViewPrivate's
8 viewItems member is cleared. This commit makes sure that viewItems is
9 restored by calling QTreeView::doItemsLayout() in this case, preventing
10 that the scroll bar range is set to zero temporarily and the view is
11 scrolled to the top unexpectedly (this was a regression in 4.7.0:
12 QTBUG-13567).
