# Candera Base

#### Cached Layout

A new (dynamic) property has been added to the [Layouter](http://dev.doc.cgistudio.at/APILINK/class_candera_1_1_layouter.html "A non-zero padding applies space inside the element layout's width and height. The values can be set ...") class: Cached Layout It specifies if the layout of the node should be performed only once until a invalidation inside the subtree occurs. A cached layout will be only laid out again as soon as the layout of an inner node is marked as invalid. See Layouter::SetCached and Layouter::IsCached.

<p class="callout info">Widgets or Behaviors shall not invalidate the scene containing a laid out node anymore, but the according node! The default value of the new property is \_False\_.</p>
