## 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

using Gio::ActionMap::ActivateSlot = sigc::slot<void>

A Slot to be called when an action has been activated, without passing a parameter to the slot.

See add_action() and add_action_bool().

For instance, void on_slot_activated();

using Gio::ActionMap::ActivateWithIntParameterSlot = sigc::slot<void, int>

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

See add_action_radio_integer().

For instance, void on_slot_activated(int parameter);

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

A Slot to be called when an action has been activated, passing a parameter of a specified type.

See add_action_with_parameter().

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

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

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

See add_action_radio_string().

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

## Member Function Documentation

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.

| ) |  |

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_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

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,
|  | gint32 | state
| ) |  |

A convenience method for creating an integer-based radio 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_radio_integer | ( | const Glib::ustring& | name,

|  | gint32 | state
| ) |  |

A convenience method for creating an integer-based radio 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

| ) |  |

A convenience method for creating a string-based radio 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_radio_string | ( | const Glib::ustring& | name,
|  | const ActivateWithStringParameterSlot& | slot,
|  | const Glib::ustring& | state
| ) |  |

A convenience method for creating a string-based radio SimpleAction instance and adding it to the ActionMap.

Parameters

  name | The name of the Action.

Parameters

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

Returns
  The Action.

Deprecated:
  This overload does not work as it does not set a parameter type on the Action, so activating it with a parameter cannot work. Use the other add_action_with_parameter() overload, which takes a parameter type.

  parameter_type | The type of parameter to be passed to the slot.
  slot | The callback method to be called when the action is activated.
