| For instance, void on_activate();.

## Constructor & Destructor Documentation

virtual Gtk::Action::~Action | ( |  | ) | `[virtual]`

Gtk::Action::Action | ( |  | ) | `[protected]`

Gtk::Action::Action | ( | const Glib::ustring& | name,
|  | const StockID& | stock_id,

|  | const Glib::ustring& | tooltip = `Glib::ustring()`
| ) | `[explicit, protected]`

## Member Function Documentation

void Gtk::Action::activate | ( |  | ) |

| Emits the "activate" signal on the specified action, if it isn't insensitive. This gets called by the proxy widgets when they get activated. It can also be used to manually activate an action. Since: 2.4

void Gtk::Action::block_activate_from | ( | Widget& | proxy | ) | `[protected]`

  | Disables calls to the activate() function by signals on the given proxy widget. This is used to break notification loops for things like check or radio actions. This function is intended for use by action implementations. Since: 2.4 Parameters:
  | proxy | A proxy widget.

void Gtk::Action::connect_accelerator | ( |  | ) |

| Installs the accelerator for action if action has an accel path and group. See set_accel_path() and set_accel_group() Since multiple proxies may independently trigger the installation of the accelerator, the action counts the number of times this function has been called and doesn't remove the accelerator until disconnect_accelerator() has been called as many times. Since: 2.4

void Gtk::Action::connect_proxy | ( | Widget& | proxy | ) |

  | Connects a widget to an action object as a proxy. Synchronises various properties of the action with the widget (such as label text, icon, tooltip, etc), and attaches a callback so that the action gets activated when the proxy widget does. If the widget is already connected to an action, it is disconnected first. Since: 2.4 Parameters:
  | proxy | The proxy widget.

virtual void Gtk::Action::connect_proxy_vfunc | ( | Widget* | proxy | ) | `[protected, virtual]`
