man Clutter::Behaviour::Ellipse (3): A behaviour interpolating position along an ellipse

SYNOPSIS

my $behaviour = Clutter::Behaviour::Ellipse->new(
Clutter::Alpha->new($timeline, 'linear'),
[ 100, 100 ], # center of the ellipse
[ 250, 250 ], # width and height of the ellipse
[ 0, 360 ], # initial and final angle
);
$behaviour->apply($icon_group);

DESCRIPTION

Clutter::Behaviour::Ellipse interpolates actors along a path defined by an ellipse.

Note: When applying an ellipse behaviour to an actor, the behaviour will update the actor's position and depth and set them to what is dictated by the ellipses initial position.
