How to change the states in Adobe Flex 3

Hello,

I`m really new to Flex and ActionScript so please be patient with me.

I want to implement this script: http://gmaps-samples-flash.googlecode.com/svn/trunk/demos/TabNavigatorInfoWindow /srcview/index.html

...that is doing this "magic": http://gmaps-samples-flash.googlecode.com/svn/trunk/demos/TabNavigatorInfoWindow /TabNavigatorInfoWindow.html#


...but I want to tweak it a little on InfoWindowTabbedComponent. To be more precise I`m trying to insert buttons in that tab, and when you click one the state will change.

I don`t know why my code is not working...you can see it in the attachment.

 

package { 
import flash.events.Event;
import flash.events.MouseEvent; 
import mx.containers.Panel;
import mx.containers.TabNavigator;
import mx.containers.VBox;
import mx.controls.Button;
import mx.core.UIComponent;
 
public class InfoWindowTabbedComponent2 extends UIComponent 
{ 
            
  public function InfoWindowTabbedComponent2() {
    // Add body text
    var tabNavigator:TabNavigator = new TabNavigator();
    tabNavigator.width = 290;
    tabNavigator.height = 150;
     //Here I`m creating 3 tabs inside TabNagivator
    tabNavigator.addChild(createTab("Utile"));
    tabNavigator.addChild(createTab("Cultura"));
    tabNavigator.addChild(createTab("Istorie"));
    tabNavigator.addChild(createTab("Link")); 
    
    
    addChild(tabNavigator);
    addChild(createTab("Parent")); 
    
    cacheAsBitmap = true;
  }
  
  //Change state function
 public function changeState():void 
  {
      currentState = "est";     
  }
  
  //Create a tab inside TabNavigator
  public function createTab(label:String):VBox 
  {
  	var tab:VBox = new VBox();
  	tab.label = label;
  	var inside:Panel = new  Panel();
  	var link:Button;
  	  	  	
  	inside.width = 280;
  	inside.height = 100;
  	inside.setStyle("borderStyle", "none");
  	
	//If the user clicks the Link tab and inside that it will click the button, the state must change
  	if (label=="Link")
  		{
  		link = new Button;
  		link.id = "lnkGoogle";
	  	link.label = "Google";
	  	
	  	link.addEventListener(MouseEvent.CLICK, changeState);
	  	
		//add the button to the tab
		inside.addChild(link);
		
		//add the tab to the TabNavigator
		tab.addChild(inside);
  	
  	return tab;
  }
} 
}
