For the decoration applied to architectural windows, see Window treatment (disambiguation).

In computing, the window decoration is a functional usability part of a window in most windowing systems. Usually the window decoration is written with the help widget toolkits. The drawing can provided by the window manager, respectively the wayland compositor, or by the client.

A windows decoration typically consists of a title bar, usually along the top of each window and a minimal border around the other three sides.[1] On Microsoft Windows this is called "nonclient area".[2]

In the predominant layout for modern window decorations, the top bar contains the title of that window and buttons which perform windowing-related actions such as

  • close
  • maximize
  • minimize
  • resize
  • roll-up

The border exists primarily to allow the user to resize the window.

Window decorations are considered important for the design of the look and feel of a desktop environment and modern systems allow for great customization of the colors, styles and animation effects used.
