<h3>Overview</h3>

<section class="section task-group-section">
<h3 id="section-defaultTimeout">
defaultTimeout
</h3>
<p>Set this to change the default timeout for all choice sets. If a timeout is not set on an individual choice set object (or if it is set to 0.0), then it will use this timeout instead. See <code><a href="../Classes/SDLChoiceSet.html#/c:objc(cs)SDLChoiceSet(py)timeout">timeout</a></code> for more details. If this is not set by you, it will default to 10 seconds.</p>

<h3 id="section-defaultLayout">
defaultLayout
</h3>
<p>Set this to change the default layout for all choice sets. If a layout is not set on an individual choice set object, then it will use this layout instead.
