Re: [flexcoders] Re: How can I block a TabNavigator ?

Okay, Agree with many here that not allowing the tabs to be clickable in a tabNavigator is a little uncommon usecase, I have a solution for the problem. I have extended TabNavigator to make TabNavigatorX, which achieves exactly what the requirement here is . Use the following code:

Main.mxml
------------------------------------------------------------------------------------------------------------

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx=" http://www.adobe.com/2006/mxml" xmlns="*" layout="absolute">
    <TabNavigatorX x="88" id="tab" y="59" width="496" height="200">
        <mx:Canvas label="Tab 1" width="100%" height="100%">
        <mx:Button label="Next >" click="tab.selectedIndex=1" x="419" y="135"/>
        </mx:Canvas>
        <mx:Canvas label="tab2" width="100%" height="100%">
        <mx:Button label="< Back" x="419" y="135" click=" tab.selectedIndex=0"/>
        </mx:Canvas>
    </TabNavigatorX>

</mx:Application>

TabNavigatorX.as
---------------------------------------------------------------------------------------------------------------
package
{
    import mx.containers.TabNavigator;
    import mx.core.Container;
    import mx.controls.TabBar
    import flash.events.Event

    public class TabNavigatorX extends TabNavigator
    {
        public function TabNavigatorX()
        {

        }
        override protected function createChildren():void
        {

            super.createChildren();

            if (!tabBar)
            {
                tabBar = new TabBar();
                tabBar.name = "tabBar";
                tabBar.focusEnabled = false;
                tabBar.styleName = this;

                tabBar.setStyle("borderStyle", "none");
                tabBar.setStyle("paddingTop", 0);
                tabBar.setStyle("paddingBottom", 0);

            }
    }
    override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void
    {
            super.updateDisplayList(unscaledWidth,unscaledHeight)
            rawChildren.addChild(tabBar);
            tabBar.setStyle("disabledOverlayAlpha",1);
            tabBar.setStyle("disabledColor",0x000000);
            tabBar.enabled=false;

           }
        }

    }


Hope this helps!

Thanks
Harish
