I _definitely_ discourage to mark Qt versions of 4.2.x as "stable", because they have a major bug regarding QTableWidgets (see provided link of the Trolltech task tracker), which causes to render only the very last line of table, all the rest will stay empty. This bug will be fixed for Qt 4.3.0, please mark all 4.2.x versions either as "testing" or even as "blocked"! Reproducible: Always
This was not a request to fix the actual bug, this was a request to mark Qt ebuilds of version 4.2.x as either "testing" or "hard masked". That's why I reopen this report now.
(In reply to comment #1) > This was not a request to fix the actual bug, this was a request to mark Qt > ebuilds of version 4.2.x as either "testing" or "hard masked". That won't happen... So, what's exactly the point of this bug? Is there a patch available? No. Does upstream know about it? Yes. So... ???
Arguably there are bugs in the 4.1 series as well. I think it's too late to go back, and there's a security issue that is making us mark 4.2.3-r1 stable as well. Since you're the first to have this issue, I'd say the problem isn't widespread. Best case, you should just locally mask this version on your system so you stay at 4.1, or try installing 4.3 beta and working with that one.
I don't doubt that there are bugs in 4.1 as well, but this is a major one. All applications that use QTableWidgets are unusable with Qt 4.2.x.
My reading is that only QTableWidgets with setSortingEnabled(true) have this issue (default is false). Since this member function was introduced in Qt-4.2 this should not hit very many people. The Qt4-gui I am currently working on has lots of QTableWidgets all of which work fine under Qt-4.2.*. Granted, I don't call setSortingEnabled(true) on my QTableWidget instances;) Best, Markus
I've also put the first beta of 4.3 into portage if you'd prefer to use that instead.
(In reply to comment #5) Yes, this bug only occurs on setSortingEnabled(true), but this method was not introduced with Qt 4.2.x, it exists as long as class "QTableWidget" exists, that is since Qt 4.0.x: http://doc.trolltech.com/4.0/qtablewidget.html#sortingEnabled-prop And IMO setSortingEnabled(true) is essential for any table that shows more than only one columnt and more than just a couple of rows. (In reply to comment #6) Good to know that a first version of Qt 4.3 is in portage. But I'm not sure if I'm brave enough to test this beta already, especially as I just realized that there is no single 4.1.x version in portage anymore where I could downgrade in case this beta introduced another severe bug(s).
closing due to 4.3 now being in the tree and stable on many arches.
And that bug has actually been fixed with that version? Qt was marked as stable for many archs before, even though this IMO major bug existed.
