var builder = MauiApp.CreateBuilder();
builder.UseMauiApp<App>()
        .ConfigureFonts(fonts =>
        {
            fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
            fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
        })
        .ConfigureLifecycleEvents(events =>
         {

#if WINDOWS
        events.AddWindows(windows => windows
        .OnWindowCreated(window =>
                      {
                          //window.SizeChanged += OnSizeChanged;
                          MauiWinUIWindow mauiwin = window as MauiWinUIWindow;
                          if (mauiwin == null) { return; }
                          
                          //关闭扩展内容
                          mauiwin.ExtendsContentIntoTitleBar = false;
                          mauiwin.Title = "Hello Maui";
                          
                          
                          通过maui窗口句柄获取appwindow---
                          ///这里有个操蛋的东西我用最新版新建的工程没法直接getappwindow所以用了文章里的方法
                          var wndId = Microsoft.UI.Win32Interop.GetWindowIdFromWindow(mauiwin.WindowHandle);
                          Microsoft.UI.Windowing.AppWindow appwin = Microsoft.UI.Windowing.AppWindow.GetFromWindowId(wndId);

                          //对于OverlappedPresenter的解释文档在这个网址
                          //https://learn.microsoft.com/zh-tw/windows/windows-app-sdk/api/winrt/microsoft.ui.windowing.overlappedpresenter?view=windows-app-sdk-1.2
                          
                          //大致就是OverlappedPresenter会设置这个窗口，这个窗口可以和其他窗口重叠，并对窗口标题栏 状态栏 工作栏进行设置，以及其他一些调整窗口的操作
                          var customOverlappedPresenter = Microsoft.UI.Windowing.OverlappedPresenter.CreateForContextMenu();
                          appwin.SetPresenter(customOverlappedPresenter);
                      }));    
#endif
            });

        return builder.Build();
