Hello,

Thanks for your hard work! I like the evolution of the tool, especially about the clang code model that improves a lot productivity.

It just happens that QTCREATORBUG-21709 (probably) is blocking me from upgrading to the 4.9. I tried the beta2 and for like one hour or two on a big project, the UI is really slow, typing takes seconds to be taken into account. After these hours, it becomes responsive again. I disabled clang code model and the result is the same. I suspect something is continuously eating the main thread CPU, even after the “parsing” message is gone.

Best regards,
Louis

Same issue with Unreal Engine via QtCreator. The best solution is to simply disable the ClangCodeModel plugin!

JD says:

Same here, I simply cannot use the ClangCodeModel plugin, because with it enabled, QtCreator takes ages to show any kind of auto completion and even longer to parse a file…
And that is on various different PCs AND operating systems, so it’s a bit of a mystery to me how anyone can actually use it.

I have reported the following blocking issue on Windows: https://bugreports.qt.io/browse/QTCREATORBUG-22211

Helmut M. says:

And Qt Creator 4.9 still does not like the padding properties (leftPadding, etc.) and others. See https://bugreports.qt.io/browse/QTCREATORBUG-22057

I’ve been pretty happy with the last two 4.9 betas. I’m curious, will the next version but 4.10 or 5.0 and what improvements are tentatively planned?

Loïc says:

Thanks for the .cxxflags/.cflags for generic project.

Is there a list of the required lib version to run QtCreator ? It does not work on debian 8 and I figured out I needed newer version of libfreetype6, lib-dbus, and libpng16.

It would be great if Qtcreator could check the required dependency at install or start to give meaningful error when this happens. But I suppose it is the usual issue with linux distribution and that there is no simple solution for that.

Elie Zedeck says:

Hi, thanks for the update. However, I think it still has too many blocking bugs. I’m not really the kind to report bugs, since the protocol to do so it too long, so TD;DD (too long, didn’t do). So, I’ll just say here as that’s simpler (life’s too short for too long stuffs).

First, in designer mode, have a:
property var members: [{“name”: “member1”}, {“name”: “member2”}]

Now, save it. It will break the value and will just leave [, ]

Secondly, this really needs to be solved, since 4.2: https://forum.qt.io/topic/72970/qt-creator-don-t-switch-to-design-mode-automatically … I mean, we’re talking 4.9 here, why is there still no option to disable auto-opening designer for UI files?

Thanks for reading, and hopefully, these will be addressed.
