/** A %ListBox is a vertical container that contains ListBoxRow

 * by a CellRenderer, or when the contents are interactive (e.g. contain a
 * button).
 *
 * Although a %ListBox must have only ListBoxRow children you can
 * add any kind of widget to it via prepend(), append() and insert(), and a ListBoxRow
 * widget will automatically be inserted between the list and the widget.

 * Also see FlowBox.
