<p><a class="link" href="ClutterBindConstraint.html" title="ClutterBindConstraint"><span class="type">ClutterBindConstraint</span></a> is a <a class="link" href="ClutterConstraint.html" title="ClutterConstraint"><span class="type">ClutterConstraint</span></a> that binds the

<p>An offset can be applied to the constraint, to avoid overlapping. The offset
can also be animated. For instance, the following code will set up three
actors to be bound to the same origin:</p>
