## Detailed Description

Activatable widgets can be connected to a Gtk::Action and reflect the state of the action.

An Activatable can also provide feedback through its action, as it is responsible for activating the related action.

Since gtkmm 2.16:

## Constructor & Destructor Documentation

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

## Member Function Documentation

static void Gtk::Activatable::add_interface | ( | GType | gtype_implementer | ) | `[static]`

void Gtk::Activatable::do_set_related_action | ( | const Glib::RefPtr< Action >& | action | ) |

This is a utility function for Gtk::Activatable implementors.

When implementing Gtk::Activatable you must call this when handling changes of the Gtk::Activatable:related-action, and you must also use this to break references in Object->dispose().

This function adds a reference to the currently set related action for you, it also makes sure the Gtk::Activatable->update() method is called when the related Gtk::Action properties change and registers to the action's proxy list.

<note>Be careful to call this before setting the local copy of the Gtk::Action property, since this function uses gtk_activatable_get_action() to retrieve the previous action</note>

Since gtkmm 2.16:

Parameters:

  action | The Gtk::Action to set.

Glib::RefPtr<Action> Gtk::Activatable::get_related_action | ( |  | ) |

Gets the related Gtk::Action for activatable.

Since gtkmm 2.16:

Returns:
  The related Gtk::Action if one is set.

Glib::RefPtr<const Action> Gtk::Activatable::get_related_action | ( |  | ) | const

Gets the related Gtk::Action for activatable.

Since gtkmm 2.16:

Returns:
  The related Gtk::Action if one is set.

bool Gtk::Activatable::get_use_action_appearance | ( |  | ) | const

Gets whether this activatable should reset its layout and appearance when setting the related action or when the action changes appearance.

Since gtkmm 2.16:

Returns:
  Whether activatable uses its actions appearance.

GtkActivatable* Gtk::Activatable::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

const GtkActivatable* Gtk::Activatable::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

Glib::PropertyProxy< Glib::RefPtr<Action> > Gtk::Activatable::property_related_action | ( |  | ) |

The action this activatable will activate and receive updates from.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< Glib::RefPtr<Action> > Gtk::Activatable::property_related_action | ( |  | ) | const

The action this activatable will activate and receive updates from.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy<bool> Gtk::Activatable::property_use_action_appearance | ( |  | ) |

Whether to use the related actions appearance properties.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly<bool> Gtk::Activatable::property_use_action_appearance | ( |  | ) | const

Whether to use the related actions appearance properties.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

void Gtk::Activatable::set_related_action | ( | const Glib::RefPtr< Action >& | action | ) |

Sets the related action on the activatable object.

<note>Gtk::Activatable implementors need to handle the Gtk::Activatable:related-action property and call do_set_related_action() when it changes.</note>

Since gtkmm 2.16:

Parameters:

  action | The Gtk::Action to set.

void Gtk::Activatable::set_use_action_appearance | ( | bool | use_appearance = `true` | ) |

Sets whether this activatable should reset its layout and appearance when setting the related action or when the action changes appearance.

<note>Gtk::Activatable implementors need to handle the Gtk::Activatable:use-action-appearance property and call sync_action_properties() to update activatable if needed.</note>

Since gtkmm 2.16:

Parameters:

  use_appearance | Whether to use the actions appearance.

void Gtk::Activatable::sync_action_properties | ( | const Glib::RefPtr< Action >& | action | ) |

This is called to update the activatable completely, this is called internally when the Gtk::Activatable::related-action property is set or unset and by the implementing class when Gtk::Activatable::use-action-appearance changes.

Since gtkmm 2.16:

Parameters:

  action | The related Gtk::Action or `0`.

virtual void Gtk::Activatable::sync_action_properties_vfunc | ( | const Glib::RefPtr< Action >& | action | ) | `[virtual]`

virtual void Gtk::Activatable::update_vfunc | ( | const Glib::RefPtr< Action >& | action,
|  | const Glib::ustring & | property_name
| ) |  | `[virtual]`

## Friends And Related Function Documentation

Glib::RefPtr< Gtk::Activatable > wrap | ( | GtkActivatable * | object,
|  | bool | take_copy = `false`
| ) |  | `[related]`

A Glib::wrap() method for this object.

Parameters:

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:
  A C++ instance that wraps this C instance.
