<para>Clutter is a GObject based library for creating fast, visually
|
||
|
|
rich, graphical user interfaces.</para>
|
||
|
|
|
||
|
|
<para>Clutter works by manipulating a scene-graph of 2D surfaces, or
|
||
|
|
'actors', inside a 3D space.</para>
|
||
|
|
|
||
|
|
<para>#ClutterActor is the base class for such surfaces. All
|
||
|
|
#ClutterActor<!-- -->s can be positioned, scaled and rotated in 3D space.
|
||
|
|
In addition, other properties can be set, such as 2D clipping, children and
|
||
|
|
opacity. Tranforms applied to a parent actor also apply to any children.
|
||
|
|
Actors are also able to receive events.</para>
|
||
|
|
|
||
|
|
<para>Subclasses of #ClutterActor include #ClutterStage, #ClutterTexture,
|
||
|
|
#ClutterLabel, #ClutterRectangle, #ClutterEntry and
|
||
|
|
#ClutterGroup. #ClutterActor<!-- -->s are added to a parent, transformed
|
||
|
|
and then made visible.</para>
|
||
|
|
|
||
|
|
<para>#ClutterStage is the top level #ClutterActor - it's the
|
||
|
|
representation of a window, or framebuffer. It is created automatically
|
||
|
|
when Clutter is initialised. #ClutterStage is a #ClutterGroup, a class
|
||
|
|
implementing the #ClutterCointainer interface.</para>
|
||
|
|
|
||
|
|
<para>#ClutterTimeline<!-- -->s provide the basis for Clutter's animation
|
||
|
|
utilities. Multiple timelines can be synchronised using #ClutterScore,
|
||
|
|
and #ClutterBehaviour and #ClutterEffect allow for the creation of
|
||
|
|
animation effects such as transitions.</para>
|
||
|
|
|
||
|
|
<para>Clutter further contains a number of utilities, including;
|
||
|
|
#ClutterScript - for loading 'UI definition' files formatted in
|
||
|
|
<ulink type="http" url="http://json.org">JSON</ulink>, #ClutterShader - a
|
||
|
|
class for applying GPU shaders to actors, #ClutterModel - a utility class
|
||
|
|
for MVC list type implementations, and fixed point math utilities.</para>
