<brief_description>
A container that creates a tab for each child control, displaying only the active tab's control.
</brief_description>
<description>
Arranges child controls into a tabbed view, creating a tab for each one. The active tab's corresponding control is made visible, while all other child controls are hidden. Ignores non-control children.
[b]Note:[/b] The drawing of the clickable tabs is handled by this node; [TabBar] is not needed.

[StyleBox] used when the [TabBar] is focused. The [theme_item tab_focus] [StyleBox] is displayed [i]over[/i] the base [StyleBox] of the selected tab, so a partially transparent [StyleBox] should be used to ensure the base [StyleBox] remains visible. A [StyleBox] that represents an outline or an underline works well for this purpose. To disable the focus visual effect, assign a [StyleBoxEmpty] resource. Note that disabling the focus visual effect will harm keyboard/controller navigation usability, so this is not recommended for accessibility reasons.
