+/// A group of exclusive toggles.
+/// 
+/// 
+/// 
+/// `AdwToggleGroup` presents a set of exclusive toggles, represented as
+/// `Toggle` objects. Each toggle can display an icon, a label, an icon
+/// and a label, or a custom child.
+/// 
+/// Toggles are indexed by their position, with the first toggle being equivalent
+/// to 0, and so on. Use the ``active(_:)`` to get that position.
+/// 
+/// Toggles can also have optional names, set via the ``name(_:)``
+/// property. The name of the active toggle can be accessed via the
+/// ``activeName(_:)`` property.
+/// 
+/// `AdwToggle` objects can be retrieved via their index or name, using
+/// `ToggleGroup.get_toggle` or `ToggleGroup.get_toggle_by_name`
+/// respectively. `AdwToggleGroup` also provides a `Gtk.SelectionModel` of
+/// its toggles via the ``toggles(_:)`` property.
+/// 
+/// `AdwToggleGroup` is orientable, and the toggles can be displayed horizontally
+/// or vertically. This is mostly useful for icon-only toggles.
+/// 
+/// Use the ``homogeneous(_:)`` property to make the toggles take
+/// the same size, and the ``canShrink(_:)`` to control whether
+/// the toggles can ellipsize.
+/// 
+/// Example of an `AdwToggleGroup` UI definition:
+/// 
+/// ```xml
+/// <object class="AdwToggleGroup"><property name="active-name">picture</property><child><object class="AdwToggle"><property name="icon-name">camera-photo-symbolic</property><property name="tooltip" translatable="yes">Picture Mode</property><property name="name">picture</property></object></child><child><object class="AdwToggle"><property name="icon-name">camera-video-symbolic</property><property name="tooltip" translatable="yes">Recording Mode</property><property name="name">recording</property></object></child></object>
