Oxygen is a classic style for KDE Plasma. Once the default style in KDE 4, it is now offered as an optional package.
This repository contains many parts of Oxygen, such as:
- Color schemes, located under /color-schemes.
- Cursors, located under /cursors.
- Air and Oxygen desktop themes, located under /desktoptheme.
- Window decorations, located under /kdecoration.
- Application style, located under /kstyle.
- Wallpapers, located under /wallpapers.
The Oxygen icon set is recommended for use alongside the rest of the theme:
- Oxygen Icons - contains the icon set associated with the Oxygen style.
The easiest way to make changes and test Oxygen during development is to build it with kde-builder.
When building Oxygen manually, keep in mind that the Qt5 and Qt6 versions will be built by default. To control which versions are built, use the BUILD_QT5 and BUILD_QT6 CMake variables.
Like other projects in the KDE ecosystem, contributions are welcome from all. This repository is managed in KDE Invent, our GitLab instance.
