DESCRIPTION

This subclass of Tickit::ContainerWidget acts as an abstract base class for widgets that contain exactly one other widget. It enforces that only one child widget may be contained at any one time, and provides a convenient accessor to obtain it.

CONSTRUCTOR

$widget = Tickit::SingleChildWidget->new( %args )

Constructs a new Tickit::SingleChildWidget object. If passed an argument called child this will be added as the contained child widget.

METHODS

$child = $widget->child

Returns the contained child widget.

$widget->set_child( $child )

Sets the child widget, or undef to remove.
