Note: The direct children of an MX navigator container must be MX containers, either MX layout or MX navigator containers, or the Spark NavigatorContent container. You cannot directly nest a control or a Spark container other than the Spark NavigatorContent container within a navigator; they must be children of an child MX container.
Like a ViewStack container, a TabNavigator container has a collection of child containers, in which only one child at a time is visible. Flex automatically creates a TabBar container at the top of the TabNavigator container, with a tab corresponding to each child container. Each tab can have its own label and icon. When the user clicks a tab, the corresponding child container becomes visible as the selected child of the TabNavigator container.
When you change the currently visible child container,
you can use the hideEffect property of the container being
hidden and the showEffect property of the newly visible child
container to apply an effect to the child containers.
The TabNavigator container waits for the hideEffect of the
child container being hidden to complete before it reveals the new child
container.
You can interrupt a currently playing effect if you change the
selectedIndex property of the TabNavigator container
while an effect is playing.
To define the appearance of tabs in a TabNavigator, you can define style properties in a Tab type selector, as the following example shows:
<fx:Style>
@namespace mx "library://ns.adobe.com/flex/mx"
mx|Tab {
fillColors: #006699, #cccc66;
upSkin: ClassReference("CustomSkinClass");
overSkin: ClassReference("CustomSkinClass");
downSkin: ClassReference("CustomSkinClass");
}
</fx:Style>
The Tab type selector defines values on the hidden mx.controls.tabBarClasses.Tab class. The default values for the Tab type selector are defined in the defaults.css file.
You can also define the styles in a class selector that you specify using
the tabStyleName style property; for example:
<fx:Style>
@namespace mx "library://ns.adobe.com/flex/mx"
mx|TabNavigator {
tabStyleName:myTabStyle;
}
.myTabStyle {
fillColors: #006699, #cccc66;
upSkin: ClassReference("CustomSkinClass");
overSkin: ClassReference("CustomSkinClass");
downSkin: ClassReference("CustomSkinClass");
}
</fx:Style>
A TabNavigator container has the following default sizing characteristics:
| Characteristic | Description |
|---|---|
| Default size | The default or explicit width and height of the first active child plus the tabs, at their default or explicit heights and widths. Default tab height is determined by the font, style, and skin applied to the TabNavigator container. |
| Container resizing rules | By default, TabNavigator containers are only sized once to fit the size of the first child container. They do not resize when you navigate to other child containers. To force TabNavigator containers to resize when you navigate to a different child container, set the resizeToContent property to true. |
| Child layout rules | If the child is larger than the TabNavigator container, it is clipped. If the child is smaller than the TabNavigator container, it is aligned to the upper-left corner of the TabNavigator container. |
| Default padding | 0 pixels for the top, bottom, left, and right values. |

getTabAt | () | method |
public function getTabAt(index:int):Button| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |

measure | () | method |
override protected function measure():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Calculates the default sizes and mininum and maximum values of this
TabNavigator container.
See the UIComponent.measure() method for more information
about the measure() method.
The TabNavigator container uses the same measurement logic as the
ViewStack container, with two modifications:
First, it increases the value of the
measuredHeight and
measuredMinHeight properties to accomodate the tabs.
Second, it increases the value of the
measuredWidth property if necessary
to ensure that each tab can be at least 30 pixels wide.

see the UIComponent.updateDisplayList() method.
A TabNavigator container positions its TabBar container at the top.
The width of the TabBar is set to the width of the
TabNavigator, and the height of the TabBar is set
based on the tabHeight property.
A TabNavigator container positions and sizes its child containers underneath the TabBar, using the same logic as in ViewStack container.
Parameters
unscaledWidth:Number — Specifies the width of the component, in pixels,
in the component's coordinates, regardless of the value of the
scaleX property of the component.
