Hiya folks,
I have a quite noob question related to theming. Is there any step-by-step guide how should I set up propery a new gtk theme? I have downloaded and installed one from Gnome Look, but after selecting it , only HighContrast theme is applied. Also want to apply it for Gnome apps.
Budgie desktop here, with totally fresh install.
Thx

    Hello,

    Etract the file to ~/.themes but make sure it isn't double folder. So it should look like this ~/.themes/<name of the theme>/theme files
    It happens sometimes that the theme is in an extra folder which you have to move up a level.

      If you need to tweak or fix a theme you might want to use GTK Inspector to reveal the CSS Nodes and try CSS modifications in real time.

      1) Install: the-widget-factory-3
      2) Enable $ sudo gsettings set org.gtk.Settings.Debug enable-inspector-keybinding true
      3) Test $ gtk3-widget-factory
      4a) Inspect: Ctrl+Shift+D = Opens the GTK inspector
      4b) $ GTK_DEBUG=interactive nemo # or some other app

      • This method usually works if the keyboard shorcut doesnt.

      Thanks for all your support.. However, I still do not have what I want.
      Long story short, I have downloaded Qogir theme from github (https://github.com/vinceliuice/Qogir-theme), but some gnome apps eg. calendar, calculator etc are not changed.
      (I know it is also in the software center, but I want to tweak to have rounded corners.)

      Previously I already did it somehow, but had to reinstall PC, and do not remembre the trick.
      Keep on trying.

        Qogir theme qogir-gtk-theme and icon theme qogir-icon-theme are in the repo. Maybe try installing those packages?

        There is also a Flathub package which can install all varients:
        sudo eopkg install flatpak
        flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
        flatpak install flathub org.gtk.Gtk3theme.Qogir{,-dark,-light,-win,-manjaro, ...}

        hegetam GNOME apps use libadwaita, and are thus not easily themable; the library forces them to use Adwaita.

        I think you can use Gradiance to set GTK4/libadwaita colors to that of other themes; don't quite remember.

          As I told, earlier the same Qogir theme was installed , I vas able to tweak, and it was applied for all gnome apps as well.
          Playing with install.sh script, it says that "gnome-shell not found, using styles for last gnome-shell version available."
          Is it something that we can look after?
          In the meantime, I tried several themes from Software Center, and none of them changed the look of gnome apps.

            hegetam That isn't something that a package from the package manager can do. If you want that, you'll have to install and update it manually.

              As @EbonJaeger stated Gnome Apps (most of them) are using libadwaita and can be altered by Gradiance. Normal theming doesn't work on them.
