/// [`ActionGroup`][crate::ActionGroup] represents a group of actions. Actions can be used to
/// expose functionality in a structured way, either from one part of a
/// program to another, or to the outside world. Action groups are often
/// used together with a [`MenuModel`][crate::MenuModel] that provides additional
/// representation data for displaying the actions to the user, e.g. in
/// a menu.
///
/// The main way to interact with the actions in a GActionGroup is to
/// activate them with [`ActionGroupExt::activate_action()`][crate::prelude::ActionGroupExt::activate_action()]. Activating an
/// action may require a [`glib::Variant`][struct@crate::glib::Variant] parameter. The required type of the
/// parameter can be inquired with [`ActionGroupExt::action_parameter_type()`][crate::prelude::ActionGroupExt::action_parameter_type()].
/// Actions may be disabled, see [`ActionGroupExt::is_action_enabled()`][crate::prelude::ActionGroupExt::is_action_enabled()].
/// Activating a disabled action has no effect.
///
/// Actions may optionally have a state in the form of a [`glib::Variant`][struct@crate::glib::Variant]. The
/// current state of an action can be inquired with
/// [`ActionGroupExt::action_state()`][crate::prelude::ActionGroupExt::action_state()]. Activating a stateful action may
/// change its state, but it is also possible to set the state by calling
/// [`ActionGroupExt::change_action_state()`][crate::prelude::ActionGroupExt::change_action_state()].
///
/// As typical example, consider a text editing application which has an
/// option to change the current font to 'bold'. A good way to represent
/// this would be a stateful action, with a boolean state. Activating the
/// action would toggle the state.
///
/// Each action in the group has a unique name (which is a string). All
/// method calls, except [`ActionGroupExt::list_actions()`][crate::prelude::ActionGroupExt::list_actions()] take the name of
/// an action as an argument.
///
/// The [`ActionGroup`][crate::ActionGroup] API is meant to be the 'public' API to the action
/// group. The calls here are exactly the interaction that 'external
/// forces' (eg: UI, incoming D-Bus messages, etc.) are supposed to have
/// with actions. 'Internal' APIs (ie: ones meant only to be accessed by
/// the action group implementation) are found on subclasses. This is
/// why you will find - for example - [`ActionGroupExt::is_action_enabled()`][crate::prelude::ActionGroupExt::is_action_enabled()]
/// but not an equivalent `set()` call.
///
/// Signals are emitted on the action group in response to state changes
/// on individual actions.
///
/// Implementations of [`ActionGroup`][crate::ActionGroup] should provide implementations for
/// the virtual functions [`ActionGroupExt::list_actions()`][crate::prelude::ActionGroupExt::list_actions()] and
/// `g_action_group_query_action()`. The other virtual functions should
