/** A container that allows reflowing its children.
 *
 * A FlowBox positions child widgets in sequence according to its
 * orientation.
 *
 * For instance, with the horizontal orientation, the widgets will be
 * arranged from left to right, starting a new row under the previous
 * row when necessary. Reducing the width in this case will require more
 * rows, so a larger height will be requested.
 *
 * Likewise, with the vertical orientation, the widgets will be arranged
 * from top to bottom, starting a new column to the right when necessary.
 * Reducing the height will require more columns, so a larger width will
 * be requested.
 *
 * The children of a FlowBox can be dynamically sorted and filtered.
 *
 * Although a FlowBox must have only FlowBoxChild children,
 * you can add any kind of widget to it via Container::add(), and
 * a FlowBoxChild widget will automatically be inserted between
 * the box and the widget.
 *
 * Also see ListBox.
