Implements IFocusManagerComponent

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The MX TabNavigator container extends the MX ViewStack container by including a TabBar container for navigating between its child containers.

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:

CharacteristicDescription
Default sizeThe 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 rulesBy 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 rulesIf 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 padding0 pixels for the top, bottom, left, and right values.

Constructor Detail

TabNavigator

()Constructor
public function TabNavigator()

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Constructor.

Method Detail

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

Returns the tab of the navigator's TabBar control at the specified index.

Parameters

index:int — Index in the navigator's TabBar control.

Returns
Button — The tab at the specified index.

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.

updateDisplayList

()method 
override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Responds to size changes by setting the positions and sizes of this container's tabs and children. For more information about the updateDisplayList() method, 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.
 
unscaledHeight:Number — Specifies the height of the component, in pixels, in the component's coordinates, regardless of the value of the scaleY property of the component.
