+ * SECTION:gtkaction
+ * @Short_description: An action which can be triggered by a menu or toolbar item
+ * @Title: GtkAction
+ * @See_also: #GtkActionGroup, #GtkUIManager, #GtkActivatable
+ *
+ * Actions represent operations that the user can be perform, along with
+ * some information how it should be presented in the interface. Each action
+ * provides methods to create icons, menu items and toolbar items
+ * representing itself.
+ *
+ * As well as the callback that is called when the action gets activated,
+ * the following also gets associated with the action:
+ * <itemizedlist>
+ * <listitem><para>a name (not translated, for path lookup)</para></listitem>
+ * <listitem><para>a label (translated, for display)</para></listitem>
+ * <listitem><para>an accelerator</para></listitem>
+ * <listitem><para>whether label indicates a stock id</para></listitem>
+ * <listitem><para>a tooltip (optional, translated)</para></listitem>
+ * <listitem><para>a toolbar label (optional, shorter than label)</para></listitem>
+ * </itemizedlist>
+ * The action will also have some state information:
+ * <itemizedlist>
+ * <listitem><para>visible (shown/hidden)</para></listitem>
+ * <listitem><para>sensitive (enabled/disabled)</para></listitem>
+ * </itemizedlist>
+ * Apart from regular actions, there are <link linkend="GtkToggleAction">toggle
+ * actions</link>, which can be toggled between two states and <link
+ * linkend="GtkRadioAction">radio actions</link>, of which only one in a group
+ * can be in the "active" state. Other actions can be implemented as #GtkAction
+ * subclasses.
+ *
+ * Each action can have one or more proxy widgets. To act as an action proxy,
+ * widget needs to implement #GtkActivatable interface. Proxies mirror the state
+ * of the action and should change when the action's state changes. Properties
+ * that are always mirrored by proxies are #GtkAction:sensitive and
+ * #GtkAction:visible. #GtkAction:gicon, #GtkAction:icon-name, #GtkAction:label,
+ * #GtkAction:short-label and #GtkAction:stock-id properties are only mirorred
+ * if proxy widget has #GtkActivatable:use-action-appearance property set to
+ * %TRUE.
+ *
+ * When the proxy is activated, it should activate its action.
