ClassikStyles is a highly customizable binary Window Decoration and Application Style plugin for recent versions of the KDE Plasma desktop. Inspired by the classic style of KDE 1, ClassikStyles is an attempt to update that classic style using a fork of KDE Breeze. Install with the instructions below, and then enable in System Settings -> Appearance -> Window Decorations, and also in System Setings -> Appearance -> Application Style.
- Also provides Oxygen/Breeze and Redmond button icon styles;
- Provides both a Window Decoration and an Application Style so that icons in dockable panels and MDI applications consistently match the titlebar icons (make sure to enable both in your Plasma Appearance settings!):
-
Configurable whether to draw bold button icons for HiDPI displays; by default automatically turns off bold icons on LoDPI 96DPI screens to prevent blurring;
-
Full-sized Rectanglar or Circular button highlights (Full-sized Rectangle is now default as has a larger clickable area):
(Above-left configuration: Button highlight style: Full-sized Rectangle, Titlebar side margins: 0, Right-hand button spacing: 10
Above-right configuration: Button highlight style: circle, Titlebar side margins: 3, Right-hand button spacing: 5)
-
Ability to inherit system colour-scheme highlight colours for hover and focus, as well as titlebar colour. Auto-enhances contrast in cases where it is poor;
-
Option to have matching titlebar colour and border colour;
-
Configurable button spacing (left and right), titlebar margins (sides, top/bottom and option for different maximized), all with scaling for HiDPI:
- Configurable corner radius, also scales with different DPIs:
- Transparency/opacity configurable for both active/inactive windows; setting to make maximized windows opaque; blur is enabled:
- GTK apps' titlebar buttons will not always update if you change a ClassikStyles setting. Workaround: you need to select another window decoration and then select ClassikStyles again to generate the GTK titlebar buttons; alternatively you can change your colour scheme and the GTK titlebar buttons will generate.
ClassikStyles from version 2.6 onwards requires a recent version of KDE Plasma with at least KDE Frameworks 5.82, so please check you have this in kinfocenter before trying to install. You can either download the pre-built packages or compile from source.
Respositories are available from the Open Build Service for OpenSUSE, Debian/KDE Neon, Fedora, Mageia and Arch/Manjaro to keep you on the latest version.
NB: for OpenSUSE Leap you will first need to install newer KDE packages, otherwise you could corrupt your system!
Raw binary packages are also available from the Open Build Service link above if you choose "Grab binary packages directly" -- a .rpm or .deb file from one of the selected distributions should also work on other distributions.
(Leap requires newer KDE packages from https://en.opensuse.org/SDB:KDE_repositories first):

To make your Plasma Desktop fully consistent, there are also matching system icon themes. These add consistent titlebar button icons to certain minor context menus in Plasma, for example, Classik-with-Square-highlight:
To obtain these icon themes go to System Settings->Appearance->Icons->Get New Icons... and search for "classikstyles". Then download your theme of choice to match your Button icon style and Button highlight style:
These icons inherit the Breeze icon theme, only overriding the titlebar button icons. To inherit a different icon theme, go to ~/.local/share/icons/ and edit the Inherits line in your index.theme file.
