`AdwToggleGroup` presents a set of exclusive toggles, represented as
[class@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 [property@ToggleGroup:active] to get that position.

Toggles can also have optional names, set via the [property@Toggle:name]
property. The name of the active toggle can be accessed via the
[property@ToggleGroup:active-name] property.

`AdwToggle` objects can be retrieved via their index or name, using
[method@ToggleGroup.get_toggle] or [method@ToggleGroup.get_toggle_by_name]
respectively. `AdwToggleGroup` also provides a [iface@Gtk.SelectionModel] of
its toggles via the [property@ToggleGroup:toggles] property.

`AdwToggleGroup` is orientable, and the toggles can be displayed horizontally
or vertically. This is mostly useful for icon-only toggles.

Use the [property@ToggleGroup:homogeneous] property to make the toggles take
the same size, and the [property@ToggleGroup:can-shrink] 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>
```

## CSS nodes

`AdwToggleGroup` has a main CSS node with the name `toggle-group`.

Its toggles have CSS nodes with the name `toggle`, and its separators have nodes
with the name `separator`.

Toggle nodes will have a different style classes depending on their content:
`.text-button` for labels, `.image-button` for icons, `.image-text-button`
for both or no style class for custom children.

The hidden separators use the `.hidden` style class.

## Style classes

`AdwToggleGroup` can use the [`.flat`](style-classes.html#flat_1) style class
to remove its background and make it look like a group of buttons.

<picture>
<source srcset="toggle-group-flat-dark.png" media="(prefers-color-scheme: dark)">
<img src="toggle-group-flat.png" alt="toggle-group-flat">
</picture>

It can also use the [`.round`](style-classes.html#round) style class to make
its toggles and the group itself rounded.

<picture>
<source srcset="toggle-group-round-dark.png" media="(prefers-color-scheme: dark)">
<img src="toggle-group-round.png" alt="toggle-group-round">
</picture>

They can also be combined with each other.

<picture>
<source srcset="toggle-group-flat-round-dark.png" media="(prefers-color-scheme: dark)">
<img src="toggle-group-flat-round.png" alt="toggle-group-flat-round">
</picture>

## Accessibility

`AdwToggleGroup` uses the `GTK_ACCESSIBLE_ROLE_RADIO_GROUP` role. Its toggles
use the `GTK_ACCESSIBLE_ROLE_RADIO` role.
