Qt Creator's integrated C++ code model / code completion doesn't work or works partially when a project becomes larger.
I am providing test project where the code completion for QOpenGLFunctions_3_3_Core doesn't work at all using the Qt Creator's integrated C++ code completion:
I've written a forum topic about this:
... and there have been discussions in the Qt Creator's mailing list as well:
There is a bugreport that target's Qt Creator's code completion problems partially:
A possible cure for the problem is to enable the Clang's C++ code model and use it. It always completes code but it is awfully slow. Explicitly requesting the code completion with Ctrl + Space or implicitly triggering it by typing, results in several seconds waiting time - 2 to 4 seconds for the code completion to arrive.
I am using the following machine:
CPU: Core i7 2600 3.4 GHz
RAM: 16 GB
SSD: Samsung SSD 840 Pro
So, hardware shouldn't be the reason for the slow Clang's code completion.
The best thing about Qt is developer experience - the joy, convenience and motivation to code. Bad code completion ruins all of these.
