Theming libadwaita in kde

Hi there, i was previously a gnome user but now i switched to kde and i am loving the experience. While customizing my desktop, i used sweet theme which i heard the most but the problem all my gtk 3 apps are themed but some flatpaks such as bottles and flatseal etc. do not get themed, I tried everything i know but nothing seemed to work

it looks like this gtk 4 style sheet is provided then also…

There’s a libadwaita fork called libadapta that allows more theming support. Don’t know how well it works with KDE.

Hi! Libadwaita applications are built to not be themable in the same way as other toolkits. Libadapta represents an attempt to recruit app developers to build applications that have the same general look-and-feel, but that respond better to theming and fit better in non-GNOME desktop environments.

Other than changing the code of the application to use different libraries, there’s just not going to be a great way to force an application that’s purpose-built with Libadwaita and the GNOME design language to look “native” in other desktop environments - especially ones with significantly different interface guidelines.

Thank you sir for explaining the whole scenario. But sir I have a doubt, while installing themes in gnome like orchid throught terminal, they are given with a option to theme libadwaita apps which worked btw. Now, I tried the same thing in kde but it didn’t turn out as I expected.

I’m no expert, but I’d guess that perhaps there’s something located differently in a GTK-based desktop environment like GNOME than in a Qt-based one like Plasma, and that theme’s installer might be pointed at the former and not the latter?
