gtk3 icon theme per application settings

HardSun · 2025-09-12 23:46:22

Hi, just wondering if anyone knows of this can be done.

I know i you can set the gtk3 theme per application as in below .desktop file, but i want to change the icon theme to match as well.
So for instance, im using the adwaita dark theme globally. But in geany i would like the application to be the adwaita light theme with papirus light icons. Doesnt seem like it can be done, ive searched for a few hours and come across old gtk2 ways of doing it.

snip ...Exec=env GTK_THEME=Adwaita:light geany %F

Hmmm..don't know the answer, but perhaps I have a tidbit that may help some. To alter Pluma which is the text-editor I use, at least insofar as internal colors, I had to mod a file in /usr/share/gtksourceview4/styles (classic, which is default in Pluma) to have an effect, these files seem to override gtk3 settings in the global theme. But I don't see anything about icons in that file currently, but perhaps that's another parameter that could be altered in that file.
