The UI Toolkit/Swing UI group in the Preferences Panel allows you to customize the Look & Feel of the Swing-based user interface. You can choose whether window decorations (such as title bars and borders) are handled by Swing or by your system's native window manager.

The available Look & Feels depend on your Java and GroIMP installation. GroIMP comes bundled with several styles, including Kunststoff, Liquid, and Tonic. Additional styles can be downloaded from Javootoo, which also provides installation instructions. The default style shown in the preferences is Java’s standard Metal Look & Feel.

When switching to a different Look & Feel in the Preferences Panel, the user interface is immediately updated. However, changes to the window decoration setting only apply to newly opened windows. Note that not all Look & Feels support window decorations.
