Maui Blazor 设置全屏以及去掉标题栏 (Windows 平台)

编辑 MauiProgram.cs 文件

1. 隐藏标题栏,隐藏边框

   • 已知问题, 可调整大小窗体, 标题栏会残留一点像素作为调整句柄

   

   

   using Microsoft.Extensions.Logging;
   using Microsoft.Maui.LifecycleEvents;
   #if WINDOWS
   using Microsoft.UI;
   using Microsoft.UI.Windowing;
   using Microsoft.UI.Xaml.Controls;
   using Microsoft.UI.Xaml;
   #endif
   
   namespace JovenResApp;
   public static class MauiProgram
   {
       public static MauiApp CreateMauiApp()
       {
           var builder = MauiApp.CreateBuilder();
           builder
               .UseMauiApp<App>()
               .ConfigureFonts(fonts =>
               {
                   fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                   fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
               });
   
   #if DEBUG
           builder.Logging.AddDebug();
   #endif
   
   #if WINDOWS     
           builder.ConfigureLifecycleEvents((events) =>
           {
               events.AddWindows(wndLifeCycleBuilder =>
               {
                   wndLifeCycleBuilder.OnWindowCreated((window) =>
                   {
                       if (window.AppWindow.Presenter is OverlappedPresenter p)
                       {
                           //p.IsResizable = false;
                           p.SetBorderAndTitleBar(false, false); 
                       }
                   });
               });
           });
   #endif
   
           return builder.Build();
       }
   }
   

2. 全屏, 不可调整窗口大小

   using Microsoft.Extensions.Logging;
   using Microsoft.Maui.LifecycleEvents;
   #if WINDOWS
   using Microsoft.UI;
   using Microsoft.UI.Windowing;
   using Microsoft.UI.Xaml.Controls;
   using Microsoft.UI.Xaml;
   #endif
   
   namespace JovenResApp;
   public static class MauiProgram
   {
       public static MauiApp CreateMauiApp()
       {
           var builder = MauiApp.CreateBuilder();
           builder
               .UseMauiApp<App>()
               .ConfigureFonts(fonts =>
               {
                   fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
                   fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
               });
   
   #if DEBUG
           builder.Logging.AddDebug();
   #endif
   
   #if WINDOWS     
           builder.ConfigureLifecycleEvents((events) =>
           {
               events.AddWindows(wndLifeCycleBuilder =>
               {
                   wndLifeCycleBuilder.OnWindowCreated((window) =>
                   {
                       window.AppWindow.SetPresenter(AppWindowPresenterKind.FullScreen);//全屏
                       if (window.AppWindow.Presenter is OverlappedPresenter p)
                       {
                           p.IsResizable = false;
                           p.SetBorderAndTitleBar(false, false); 
                       }
                   });
               });
           });
   #endif
   
           return builder.Build();
       }
   }
   
   

3. 如果不需要部署为Maui平台,其实可以简单使用 Wpf blazor hybird

   简简单单就实现

   WindowState="Maximized"  WindowStyle="None"
