WindowedApplication :如何在扩展Flex类的Flex类中制作本机菜单

import mx.core.WindowedApplication;

public class MyApplication extends WindowedApplication {
    // 添加自定义代码
}

import mx.controls.Menu;
import mx.controls.MenuBar;
import mx.controls.menuClasses.MenuItem;

public class MyApplication extends WindowedApplication {
    public function MyApplication() {
        // 创建菜单栏
        var menuBar:MenuBar = new MenuBar();
        
        // 创建菜单项
        var fileMenu:Menu = new Menu();
        var fileMenuItem:MenuItem = new MenuItem();
        fileMenuItem.label = "File";
        
        // 将菜单项添加到菜单栏
        fileMenu.addItem(fileMenuItem);
        menuBar.dataProvider = [fileMenu];
        
        // 将菜单栏添加到应用程序
        this.addChild(menuBar);
    }
}

import mx.core.Application;

public class Main extends Application {
    public function Main() {
        var myApp:MyApplication = new MyApplication();
        myApp.start();
    }
}
