Re: how do i make qt applications use papirus icons
Have you told your environment to use this?
For example Niri needs this
"QT_QPA_PLATFORMTHEME" "qt6ct"It seems hyprland needs this
QT_QPA_PLATFORMTHEME=qt6cthttps://bbs.archlinux.org/viewtopic.php?id=300251

Re: how do i make qt applications use papirus icons
the thing is that even when i open qt5ct and qt6ct, the papirus icons option does show up only the names. the icon preview shows something else

Re: how do i make qt applications use papirus icons
Did you miss the warning at the top, you need to configure it to work, is hyprland not using qt6? If so you need to set and use the qt6 versions.

Re: how do i make qt applications use papirus icons
You see that the variables are not applied. The two applications tell you so.
Does it tell you what's missing from the configuration?

Re: how do i make qt applications use papirus icons
yup i did this
hl.env("XCURSOR_SIZE", "48")
hl.env("HYPRCURSOR_SIZE", "72")
hl.env("QT_QPA_PLATFORM", "wayland;xcb")
hl.env("QT_QPA_PLATFORMTHEME", "qt5ct")
--hl.env("QT_STYLE_OVERRIDE", "kvantum")
the error was only for the kvantum override. i fixed that by commenting it and changing the theme from qt6ct itself and that's fine and all but the icons are still like in the images i shared

Re: how do i make qt applications use papirus icons
Why are you not using the qt6ct platform theme?
What makes you think the theme is "wrong"?
Looks pretty much like the action icons in https://github.com/PapirusDevelopmentTe … er/Papirus ?
