Raw Normal View History

Initial import from the monolithic Qt. This is the beginning of revision history for this module. If you want to look at revision history older than this, please refer to the Qt Git wiki for how to use Git history grafting. At the time of writing, this wiki is located here: http://qt.gitorious.org/qt/pages/GitIntroductionWithQt If you have already performed the grafting and you don't see any history beyond this commit, try running "git log" with the "--follow" argument. Branched from the monolithic repo, Qt master branch, at commit 896db169ea224deb96c59ce8af800d019de63f12

IMPORTANT.
In this testcase i follow a different approach than usual: I don't use the full power of
QtTestTable and QtTestData. This is done deliberately because QtTestData uses a QDataStream
itself to handle its data. So it would be a bit inapropriate to fully rely on QtTestData in this
testcase.
I do use QString in QtTestData because this is thouroughly tested in the selftest.
