Starling Feathers Controls ScreenNavigator

说明：

The ScreenNavigator class offers a powerful system for displaying screens or menus in your application and navigating between them. It supports navigation based on events (or as3-signals, if you prefer), and it can inject properties into screens as they
are shown.

示例：

var navigator:ScreenNavigator = new ScreenNavigator();
navigator.addScreen( "start", new ScreenNavigatorItem( MenuScreen) );
navigator.addScreen( "options", new ScreenNavigatorItem( OptionsScreen) );
this.addChild( navigator );

navigator.showScreen( "start" );
navigator.addEventListener("showOptions",showOptions);
function showOptions(e:Event):void{
navigator.showScreen("options");
}

MenuScreen代码：

package lft.fctest
{
import feathers.controls.Button;
import feathers.controls.Screen;

import starling.events.Event;

/**

public class MenuScreen extends Screen
{
public function MenuScreen()
{
super();
}
override protected function initialize():void{
var button:Button=new Button();
button.label="点击切换到options";
addChild(button);
button.addEventListener(Event.TRIGGERED,buttonTriggered);
}

private function buttonTriggered(e:Event):void
{
dispatchEventWith("showOptions",true);
}
}
}
OptionsScreen代码

package lft.fctest
{
import feathers.controls.PanelScreen;

/**
* Author:大飞狼
* <br>Date: 2014-9-11 下午3:53:42
* <br>Synopsis:
*/
public class OptionsScreen extends PanelScreen
{
public function OptionsScreen()
{
super();

}
override protected function initialize():void
{
super.initialize();
this.headerProperties.title = "Options";
}
}
}

效果：
