Clutter is a GObject based library for creating fast, visually rich graphical user interfaces. Clutter semantics work by having a stage (a window) and then adding actors (widgets) to the stage and manipulating via the actor api. Actors can contain child actors (ClutterGroup for example) and be manipulated as a whole. Animations and visual effects can be created via the use of timelines and behaviours. Timelines provide accurate frame based animations. Behaviours further extend this by taking a timeline, a control function (ClutterAlpha) and then applying to actors as to modify a property as a function of time. Clutter depends on the following libraries: GLib A general-purpose utility library, not specific to graphical user interfaces. GLib provides many useful data types, macros, type conversions, string utilities, file utilities, a main loop abstraction, and so on. GObject The GLib Object System provides the required implementations of a flexible, extensible and intentionally easy to map (into other languages) object-oriented framework for C. Pango Pango is a library for laying out and rendering of text, with an emphasis on internationalization. GDK-Pixbuf GDK-Pixbuf is a library for loading and manipulating various image file formats. FIXME: Linux, Windows, OSX. Embedded? Clutter is usually compiled against a specific drawing backend. All backends have a common API for querying the underlying platform, and some of them might have specific API exposed by Clutter. This section contains additional useful documentation for developing with Clutter. &clutter-SubclassingActor; &clutter-animation; &creating-your-own-behaviours; This library is free software; you can redistribute it and/or modify it under the terms of the GNU Library General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
