| dataProvider | property | 
dataProvider:Object  [read-write] Data used to populate the navigator control. The type of data can either be a ViewStack container or an Array.
When you use a ViewStack container, the label
      and icon properties of the ViewStack container's children
      are used to populate the navigation items,
      as in the following example:
      <mx:LinkBar dataProvider="{vs}"/>
      <mx:ViewStack id="vs">
        <mx:VBox label="Accounts" icon="account_icon"/>
        <mx:VBox label="Leads" icon="leads_icon"/>
      </mx:ViewStack> 
      
      The LinkBar control contains two links: "Accounts" and "Leads," each with its own icon as specified on the VBox tags. When you click a link, the ViewStack container navigates to the corresponding view.
When you use an Array, the labelField property
      determines the name of the dataProvider field
      to use as the label for each navigation item; the iconField
      property determines the name of the dataProvider field
      to use as the icon for each navigation item. 
      If you use an Array of Strings, the labelField
      property is ignored.
 The default value is "undefined".
This property can be used as the source for data binding.
    public function get dataProvider():Object
    public function set dataProvider(value:Object):void
| iconField | property | 
iconField:String  [read-write] 
      Name of the field in the dataProvider object
      to display as the icon for each navigation item. 
           
 The default value is "icon".
This property can be used as the source for data binding.

 The default value is "label".
This property can be used as the source for data binding.
    public function get labelField():String
    public function set labelField(value:String):void
| labelFunction | property | 
labelFunction:Function  [read-write] 
      A user-supplied function to run on each item to determine its label.  
      By default, the component looks for a property named label 
      on each data provider item and displays it.
      However, some data sets do not have a label property
      nor do they have another property that can be used for displaying.
      An example is a data set that has lastName and firstName fields
      but you want to display full names.
           
You can supply a labelFunction that finds the 
      appropriate fields and returns a displayable string. The 
      labelFunction is also good for handling formatting and 
      localization. 
For most components, the label function takes a single argument which is the item in the data provider and returns a String.
      myLabelFunction(item:Object):String
                 The default value is null.
This property can be used as the source for data binding.
    public function get labelFunction():Function
    public function set labelFunction(value:Function):void
| selectedIndex | property | 
selectedIndex:int  [read-write] Index of the active navigation item, where the first item is at an index of 0.
 The default value is -1.
This property can be used as the source for data binding.
    public function get selectedIndex():int
    public function set selectedIndex(value:int):void
| toolTipField | property | 
toolTipField:String  [read-write] 
      Name of the the field in the dataProvider object
      to display as the tooltip label.
      
      
 The default value is "toolTip".
This property can be used as the source for data binding.
