Qt Creator: Locator takes very long time to appear
-
Hello everyone,
I'm experiencing a serious usability issue with Qt Creator 6.0.2.
The issue:
When Ctrl+K is pressed, it takes 3+ seconds for the Locator to pop up. Subsequent uses soon after are pretty fast. But, after not using Ctrl+K for about a minute, the next invocation lags for several seconds before appearing.
It was not like this before. Locator used to allow me to navigate large code bases at the speed of thought. It would pop up the instant Ctrl+K was pressed. It "just worked". It was a joy to use. It never made me want to rage quit.
The problem crept in sometime around the last 4.x version of Qt Creator. At that time I was not using Creator much so I was annoyed but didn't think much of it.
Now, even working on a small, newly-created Qt Widgets project (with only 2 source files, mainwindow.h and mainwindow.cpp), using the Locator is an unnaturally irritating experience.
Things I've done to try to resolve this:
- Turned off all plugins. Tried different combinations of plugins enabled / disabled.
- Result: no change
- Wiped all Qt directories (C:\Qt). Did a fresh re-install of Qt and Qt Creator.
- Result: no change
Some other details:
- Platform: Windows 10 64-bit on a machine with 12-core CPU and 64GB RAM. Lots of free disk space.
- Project type: I most commonly work with CMake and generic C or C++ projects, and both exhibit the horrifically laggy Locator pop up issue
I am at my wits' end...
Has anyone else experienced this? If so, did you managed to resolve it? What did you do?
Thank you!

I've never experienced this, for me the locator always runs extremely fast.
Perhaps you need to wipe Qt Creator settings (on Linux they're in
.config/QtProject/but on Windows I don't know... search for file nameQtCreator.db). Maybe some old cache entries are slowing it down for you.Also, please consider reporting this on Qt bug tracker.

@sierdzio I tried your suggestion to wipe the Qt Creator settings, caches, etc. from my user directory (on Windows, these can be found at
C:\Users\$USERNAME\AppData\Roaming\QtProject).It worked! Locator is fast again!
I had to reconfigure a few things in Qt Creator, which I had previously, but that was no problem.
Thank you very much.
