+ * @short_description: Widget representing the application menu in the Hildon framework.
+ *
+ * The #HildonAppMenu is a GTK widget which represents an application
+ * menu in the Hildon framework.
+ *
+ * This menu opens from the top of the screen and contains a number of
+ * entries (#GtkButton) organized in two columns. Entries are added
+ * left to right and top to bottom.
+ *
+ * Besides that, the #HildonAppMenu can contain filter buttons
+ * (#GtkToggleButton or #GtkRadioButton), which can be grouped.
+ *
+ * <example>
