QT Apps do not respect Adwaita-dark colorscheme
OnlyOffice file chooser and Calibre do not respect my Adwaita-dark colorscheme.
What did I do wrong?
I installed `adwaita-qt{5,6}`, set them up with `qt{5,6}ct` and also installed `xdg-desktop-portal` and its GTK implementation `xdg-desktop-portal-gtk`.
I also exported `QT_QPA_PLATFORMTHEME=qt5ct` globally.
Is there something similiar for QT6?

Re: QT Apps do not respect Adwaita-dark colorscheme
Seems like just setting `QT_QPA_PLATFORMTHEME=qt6ct` resolves the issue with Calibre.
The issue with OnlyOffice remains however.

Re: QT Apps do not respect Adwaita-dark colorscheme
install qgnomeplatform-qt5 & qgnomeplatform-qt6 (adwaita-qt5 & adwaita-qt6 are dependencies of them), that's all you need to do. Do not use qt5ct / qt6ct or kvantum, they're not related. Make sure neither QT_QPA_PLATFORMTHEME nor QT_STYLE_OVERRIDE are set. You may need to reboot afterward.

Re: QT Apps do not respect Adwaita-dark colorscheme
I did all the things you described.
How do I set the theme now?
I should have maybe said in the beginning, that I am not using GNOME or any DE, but rather a WM.

Setting `QT_QPA_PLATFORMTHEME='gnome'` seems to work. Is that what I am supposed to do now?

Re: QT Apps do not respect Adwaita-dark colorscheme
Yes, I was just typing that before I saw your new reply.
There's no theme to set, Qt applications will automatically use the Adwaita / Adwaita-dark theme.
OnlyOffice does not respect the desktop theme if I remember right. Check the settings, I believe it has it's own theme setting.

Although it breaks my fontconfig on Calibre and also does not work for OnlyOffice.
