+ * ## GtkPopover as menu replacement
+ *
+ * GtkPopover is often used to replace menus. To facilitate this, it
+ * supports being populated from a #GMenuModel, using
+ * gtk_popover_new_from_model(). In addition to all the regular menu
+ * model features, this function supports rendering sections in the
+ * model in a more compact form, as a row of icon buttons instead of
+ * menu items.
+ *
+ * To use this rendering, set the ”display-hint” attribute
+ * of the section to ”iconic” and set the icons of your items with
+ * the ”verb-icon” attribute.
