## Implemented Interfaces

StBoxLayout implements ClutterContainer, ClutterScriptable, ClutterAnimatable and AtkImplementorIface.

## Description

The StBoxLayout arranges its children along a single line, where each child can be allocated either its preferred size or larger if the expand option is set. If the fill option is set, the actor will be allocated more than its requested size. If the fill option is not set, but the expand option is enabled, then the position of the actor within the available space can be determined by the alignment child property.
