The `AdwTabBar` widget is a tab bar that can be used with conjunction with
`AdwTabView`. It is typically used as a top bar within [class@ToolbarView].

`AdwTabBar` can autohide and can optionally contain action widgets on both
sides of the tabs.

When there's not enough space to show all the tabs, `AdwTabBar` will scroll
them. Pinned tabs always stay visible and aren't a part of the scrollable
area.

## CSS nodes

`AdwTabBar` has a single CSS node with name `tabbar`.

## Style classes

By default `AdwTabBar` look like a part of an `AdwHeaderBar` and is intended
to be used directly attached to one or used as a [class@ToolbarView] toolbar.
The [`.inline`](style-classes.html#inline) style class removes its background,
so that it can be used in different contexts instead.
