Tickit::SingleChildWidget - abstract base class for widgets that contain a single other widget
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.
$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.
$child = $widget->child
Returns the contained child widget.
$widget->set_child( $child )
Sets the child widget, or
undef to remove.
