/**
 * A GtkFlowBox 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 GtkFlowBox can be dynamically sorted and filtered.
 * 
 * Although a GtkFlowBox must have only #GtkFlowBoxChild children,
 * you can add any kind of widget to it via gtk_container_add(), and
 * a GtkFlowBoxChild widget will automatically be inserted between
 * the box and the widget.
 * 
 * Also see #GtkListBox.
 * 
 * GtkFlowBox was added in GTK+ 3.12.
