I have the same problem, did you find the solution?
Hi, and welcome!
First, make sure that you are not committing your project's *.pro.user file (or CMakeLists.txt.user file) into Git. These files are only valid for the machine that generates them, so they should be ignored (by specifying them in your .gitignore file)
I have added my installed Qt versions to the plugin.
Let's do a sanity check first: Select "Create a new project" > "Qt Widgets Application". After entering a project name, you should get a dialog that says "Welcome to the Qt Widgets Application Wizard", and the wizard should let you select a "Qt Version".
Are you able to see your installed Qt versions in the list?
I have manually added Additional Qt Header Search Paths. I have tried Additional include directories under the normal project settings.
I can't believe that in 2023 we have to do this.. While some text editor made by a solo developer supports language change (e.g. Notepad++).
It tool nearly 12 years to make developers of Qt Creator add that feature to..Windows version of Creator. Or permit use source files with encoding that aren't "OS native" in their mind. Oddly enough, features exist on Linux version, just not on Widows.
Absense of QoL features in Creater along with clunky interface cause so much stigma that it is considered worst IDE in some corporate workspaces (e.g. my company) and people avoid it. Similar issues with Designer causes developers to move away from Native widgets to QML or ditch Qt UI altogether and use somethign else (OSG,of example). Is this actually the plan?
