     1.7 +Subject: [PATCH] QTreeView: do not scroll to top if last item is removed
     1.8 +
     1.9 +When the last item is the current item and is removed,
    1.10 +QTreeViewPrivate::updateScrollBars() is called after QTreeViewPrivate's
    1.11 +viewItems member is cleared. This commit makes sure that viewItems is
    1.12 +restored by calling QTreeView::doItemsLayout() in this case, preventing
    1.13 +that the scroll bar range is set to zero temporarily and the view is
    1.14 +scrolled to the top unexpectedly (this was a regression in 4.7.0:
    1.15 +QTBUG-13567).
