Clearlooks
Encyclopedia
Clearlooks is a theme engine for GTK+
, the main widget toolkit
used by the GNOME
desktop environment. It is based on Red Hat
's Bluecurve
theme. The theme engine draws the actual widgets, and can be configured with 'themes' that invoke the theme engine with different configurations. It is the default theme for GNOME since version 2.12 . Many users have contributed themes that have changed the colors and some visual effects, leading to many derivative themes on sites such as art.gnome.org and GNOME-Look.
The creators of the Clearlooks Gtk engine were Richard Stellingwerff and Daniel Borgmann; however, since 2005 the engine is developed by GNOME, and current developers are Andrea Cimitan and Benjamin Berg.
The current version of Clearlooks uses Cairo
as a backend. Older releases just use GDK
to draw the widgets.
Qt
, versions 4.2 to 4.4, uses a port of Clearlooks called Cleanlooks to better integrate with GTK applications.
