#include "stage/model/expander-revealer.hpp"

Description

Functor component to support the default implementation of expanding/collapsing.

It is built based on closures (lambdas) to explicate how to detect the expansion state of the widget in question and how actively to expand or collapse it. A default constructed Expander disables this feature – which can be detected through the #canExpand() function.
