/**
 * > In GTK+ 3.10, GtkAction has been deprecated. Use #GAction
 * > instead, and associate actions with #GtkActionable widgets. Use
 * > #GMenuModel for creating menus with gtk_menu_new_from_model().
 * 
 * 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:
 * 
 * - a name (not translated, for path lookup)
 * 
 * - a label (translated, for display)
 * 
 * - an accelerator
 * 
 * - whether label indicates a stock id
 * 
 * - a tooltip (optional, translated)
 * 
 * - a toolbar label (optional, shorter than label)
 * 
 * 
 * The action will also have some state information:
 * 
 * - visible (shown/hidden)
 * 
 * - sensitive (enabled/disabled)
 * 
 * Apart from regular actions, there are [toggle actions][GtkToggleAction],
 * which can be toggled between two states and
 * [radio actions][GtkRadioAction], 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.
