[flexcoders] Dynamically change the root label of a MenuBar

Wed, 28 Dec 2005 08:21:18 -0800

Hi,
I'm trying to dynamically change the root label of a MenuBar.
I had to use: "menuBar.dataProvider = menuBar.dataProvider;" to see my changes, but now there is no sub-menus anymore.
Is it the right way to do this with Flex 2?
Thanks,
Nicolas

<mx:Application xmlns:mx="http://www.macromedia.com/2005/mxml" xmlns="*">
    <mx:Script>
        <![CDATA[
            // Import the MenuEvent class.
            import mx.events.MenuEvent;
       
            // Function that will change the "Root" label to "Has been changed"
            // when selecting any sub-menu
            private function changeEvt(event:MenuEvent):Void {
                event.menuItem.getParent().getParent().setProperty("label", "Has been changed", true);
                // I had to do this to see the new label
                menuBar.dataProvider = menuBar.dataProvider;
            }
        ]]>
    </mx:Script>
   
    <mx:XML id="menuData">
        <node label="Root">
            <node label="Level 1">
                <society label="Level 11" />
                <society label="Level 12" />
            </node>
            <node label="Level 2">
                <society label="Level 21" />
                <society label="Level 22" />
            </node>
        </node>
    </mx:XML>
   
    <mx:MenuBar id="menuBar" dataProvider="{menuData}" change="changeEvt(event)" />
   
</mx:Application>
