[GTK Integration] Apply the same theme for GTK2 and GTK3 applications
GTK configuration in Plasma depends on xsettings daemon, that has no separation between GTK2 and GTK3 theme, therefore separate themes for GTK2 and GTK3 are impossible, while this daemon is working. The daemon itself provides the functionality to apply settings to GTK applications without restarting them.
The functionality to apply different themes to applications, depending on the framework version isn't necessary, when 99% of the themes are compatible with both versions and when most of the applications are using the last GTK version anyway.
Given all that, I think, that a theme selection must be narrowed to one and only one theme for both versions of the GTK framework.
⚙ Depends on
- Apply kde-gtk-config!7 (merged)
- Restart Kded5
- Open Application Style KCM > GTK Style
- Change GTK Theme, check if both GTK2 and GTK3 apps have the same theme
- Check Get New... is working
