Qt Creator and other tools

Was that a Qt 4 project or already a Qt 5 one ?
Can you share the .pro file ?

The problem? PLUGIN writers are not respecting/inheriting QPalette properly, and are using hard coded defaults and saying "ah good enough". It seriously sucks having to forfiet the entire dark mode just because state charts are white--but i couldnt stand the constant going back/forth from dark to white. So in essence, for me, dark mode isn't useful.

Yes there is dark mode, no plugin and qch help makers are ignoring the palette and giving us no possible way to customize it.

issue was resolved when i regenerate this component~~
It should be an issue where the class name and component name do not correspond

Not sure if it's correctly translated from german but 'Extras' -> 'Formular Designer' -> 'Preview'

Yes, I tried. But it is not possible to compile the project on qt5 and it is not possible to reopen the same project from qt design studio if I change the settings in the CMake file

Don't hesitate to open new topics if other issues arise.

@Bondrusiek
If you do not Use clangd then it uses an old, internal one which is not maintained/changed much any longer.

@sungb That's too old.

Qt Creator 15.0.0 is using Qt 6.8 and the platform requirements are at https://doc.qt.io/qt-6/supported-platforms.html

Windows 10 (1809 or later)

I got even deeper into the problem. It turns out that if the "Default for "Run in terminal"" option is enabled (Edit - Preferences - Build & Run), then this error will occur. Everything returns to normal if you disable this option.

I think it is a bug: https://bugreports.qt.io/browse/QTCREATORBUG-32205

https://bugreports.qt.io/issues/?jql=project %3D QTCREATORBUG AND text ~ "focus freeze" pointed to https://bugreports.qt.io/browse/QTCREATORBUG-28957 but this was fixed in Qt Creator 10.

Hi and welcome to devnet,

That looks rather like a bug.

Did you already check the bug report system for something similar ?

I have solved this problem by installing the same version of qt creator in the original directory and then uninstalling it

@surfcius , @Christian-Ehrlicher
In my code as pasted, Creator 13 I think (unless it's 11?), clang code completer too, I do not get that warning in the IDE. I don't believe I have touched any clang settings, I suspect my C++ is C++17. Why do I not get it?

@Perdrix
Yes, I think message

qt.qpa.xcb: could not connect to display

is the clue. I think that when xcb fails to load, their misleading message about libxcb-cursor0 notwithstanding, you get an explicit "failed to load" but not "could not connect to display". I think you only get that one when DISPLAY is wrong.

Hi @jsulm
Thanks for you response :-)

I think i have setup the sysroot correctly. In the "Preferences" -> "Kits" and under the Sysroot, i have defined:
/opt/fsl-imx-wayland/6.6-scarthgap-imx-full-image/sysroots/cortexa7t2hf-neon-poky-linux-gnueabi
