## Detailed Description

ActionMap - Interface for action containers.

The ActionMap interface is implemented by ActionGroup implementations that operate by containing a number of named Action instances, such as SimpleActionGroup.

One useful application of this interface is to map the names of actions from various action groups to unique, prefixed names (e.g. by prepending "app." or "win."). This is the motivation for the 'Map' part of the interface name.

Since glibmm 2.32:

## Member Typedef Documentation

typedef sigc::slot<void> Gio::ActionMap::ActivateSlot

See add_action().

For instance, void on_slot_activated();

typedef sigc::slot< void, int > Gio::ActionMap::ActivateWithIntParameterSlot

A Slot to be called when an action has been activated.

See add_action_radio_int().

For instance, void on_slot_activated(const Glib::VariantBase& parameter);

typedef sigc::slot< void, const Glib::VariantBase& > Gio::ActionMap::ActivateWithParameterSlot

A Slot to be called when an action has been activated.

See add_action_with_parameter().

For instance, void on_slot_activated(const Glib::VariantBase& parameter);

typedef sigc::slot< void, const Glib::ustring& > Gio::ActionMap::ActivateWithStringParameterSlot

## Member Function Documentation

Glib::RefPtr<SimpleAction> Gio::ActionMap::add_action | ( | const Glib::ustring& | name | ) |

A convenience method for creating a SimpleAction instance and adding it to the ActionMap.

Parameters

  name | The name of the Action.
  slot | The callback method to be called when the action is activated.

Returns
  The Action.

Glib::RefPtr<SimpleAction> Gio::ActionMap::add_action | ( | const Glib::ustring& | name,
|  | const ActivateSlot& | slot
| ) |  |

A convenience method for creating a SimpleAction instance and adding it to the ActionMap.

Parameters

  name | The name of the Action.
  slot | The callback method to be called when the action is activated.

Returns
  The Action.

void Gio::ActionMap::add_action | ( | const Glib::RefPtr< Action >& | action | ) |

Adds an action to the action_map.

If the action map already contains an action with the same name as action then the old action is dropped from the action map.

The action map takes its own reference on action.

Since glibmm 2.32:

Parameters

  action | A Action.

Glib::RefPtr<SimpleAction> Gio::ActionMap::add_action_bool | ( | const Glib::ustring& | name,
|  | bool | state = `false`
| ) |  |

A convenience method for creating a boolean-stateful SimpleAction instance and adding it to the ActionMap.

Parameters

  name | The name of the Action.
  state | The initial state.

Returns
  The Action.

Glib::RefPtr<SimpleAction> Gio::ActionMap::add_action_bool | ( | const Glib::ustring& | name,
|  | const ActivateSlot& | slot,
|  | bool | state = `false`
| ) |  |

A convenience method for creating a boolean-stateful (toggle) SimpleAction instance and adding it to the ActionMap.

Parameters

  name | The name of the Action.
  slot | The callback method to be called when the action is activated.
  state | The initial state.

Returns
  The Action.

Glib::RefPtr<SimpleAction> Gio::ActionMap::add_action_radio_integer | ( | const Glib::ustring& | name,
