Starling Feathers Controls Screen

说明：
The ScreenNavigator component can display any Feathers control as a screen. However, using the Screen class as your base class for a new screen is recommended because it provides a number of convenient properties.

示例：

package
			{
				import feathers.controls.Screen;
				
				public class CustomScreen extends Screen
				{
					public function CustomScreen()
					{
					}
					
					override protected function initialize():void
					{
						//runs once when screen is first added to the stage.
						//a good place to add children and set a layout.
					}
					
					override protected function draw():void
					{
						//override only if you want to do manual measurement and layout.
					}
				}
			}

效果：
无。
