gtk3-classic

(Previously known as gtk3-mushrooms)

This repository contains patches to restore GTK3's look & feel reminiscent to earlier versions. With many enhancements such as disabled CSD headers, traditional dialog boxes and file browser improvements.

These are designed to work on non-GNOME desktops (such as XFCE and MATE) as well as any other environment where GTK applications are used. Running on GNOME desktops is not recommended!

Packages

Arch

Currently, these are packaged in the AUR as gtk3-classic, which is based on the official gtk3 package. Use an AUR helper (such as yay) to install the package(s):

yay -S gtk3-classic lib32-gtk3-classic

This package does not include examples or tests.

If you've previously installed gtk3-mushrooms, switch to this new package.

Problems?

These patches are unofficial and are not supported by GTK developers nor your distribution. If you are having trouble with an application or theme, try installing gtk3 and confirm it's definitely a problem with these builds.

Ideally, it would be most helpful to isolate the problematic patch by excluding it in your PKGBUILD and reinstalling.

Contributing

We aim to keep the patches rolling across new upstream GTK3 versions where possible. Due to our limited knowledge with C, we'd appreciate any help in fixing bugs caused by patches or any new contributions.

Patches should not break GTK3 or any applications, and should offer "classic" functionality as seen in GTK2 or early versions of GTK3.
