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.

Uma função fornecida pelo usuário para ocorrer em cada item para determinar seu 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. Um exemplo é o conjunto de dados que tem os campos lastName e firstName mas você quer mostrar os nomes inteiros.

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.
