It was first time when new version of QtCreator disappointed me.

It was first time when new version of QtCreator disappointed me.

I’m talking about QtCreator 4, and its new feature turned on by default – ClangCodeModel. I have 16 Gb RAM, not worst processor i5-3320M and all code I’m working on is located on SSD. Use Ubuntu 16.04×64 with XFCE, Qt 5.6 and gcc. Seems like perfect environment. Unfortunately, ClangCodeModel requires me to wait on each code-completion pop-up window. It drives me crazy!

All the time I code QtCreator seemed most speedy environment for C++/Qt with comprehensive debug tools and lots of pleasure stuff in it.

To show how it is slow I’ve recorded a video:


Of course, ClangCodeModel is switchable – anyone could switch it off. But I can’t understand why does developers of QtCreaor introduced such things enabled by default.


Another questionable moment is that each time I want turn off ClangCodeModel – I need go to Help -> About plugins..., turn it off and restart creator. To compare with QtCreator 3.6 – there was checkbox in Tools -> Options... -> C++ Tab -> Code model Tab where I could turn off Clang Code model Warnings.


If anyone could shed a light on what am I doing wrong – please do it. Otherwise, it makes me sad…
