Revert "Fixed a crash in QListView"
qdoc: Completed task QTBUG-18790
qdoc: Completed task QTBUG-18733
Benchmark for layout hierarchies
Manual test for layout flickering
Improve invalidate() testcase.
Avoid flicker when invalidate is propagated in a widget/layout hierarchy
Do not call setSizePolicy from ctor, it might call a virtual function
qdoc: Last commit before merge into master.
Fixed a crash in QListView
Doc: Fixed reference to a name in a table.
qdoc: Fixed license comment.
Ensured that incomplete downloads are removed.
qdoc: Added missing copyright notice
