 | Because this component does not define a skin for the mobile theme, Adobe recommends that you not use it in a mobile application. Alternatively, you can define your own mobile skin for the component. For more information, see Basics of mobile skinning. |
The TabBar class displays a set of identical tabs. One tab can be selected at a time, and the first tab is selected by default. The TabBarSkin class arranges the tabs in a single row. Use the TabBar
cornerRadius style to configure the corner radius
of the tabs.
The set of tabs is defined by the dataProvider property.
The appearance of the TabBar is defined by the TabBarSkin class.
The appearance of each tab is defined by the TabBarButtonSkin class.
You can use the TabBar control to set the active child of a ViewStack container, as the following example shows:
Note: The Spark list-based controls (the Spark ListBase class and its subclasses
such as ButtonBar, ComboBox, DropDownList, List, and TabBar) do not support the BasicLayout class
as the value of the layout property.
Do not use BasicLayout with the Spark list-based controls.

</s:NavigatorContent>
<s:NavigatorContent id="accountInfo" label="Account Info">
<s:Label text="Account Info"/>
</s:NavigatorContent>
</mx:ViewStack>
The TabBar container has the following default characteristics:
| Characteristic | Description |
|---|---|
| Default size | Large enough to display the tabs |
| Minimum size | 0 pixels |
| Maximum size | 10000 pixels wide and 10000 pixels high |

Skinonderdelen
Deze component gebruikt skins die zijn gemaakt van skinonderdelen. Stel de skinonderdelen niet onmiddellijk in. De skin van het component stelt de skinonderdelen in.
Skinstatussen
Als u de skin van een component wilt instellen, implementeert u een skin dat de volgende statussen definieert. Hoewel u alle skinstatussen moet implementeren, kan een skinstatus leeg zijn. Een lege skinstatus geeft aan dat er geen wijzigingen zijn gebeurd in de standaardskinstatus.
