Hello, I have a question that I always wanted to ask related to Windows Title bar (i'm talking about this one):User's image

When .NET 8 released, I saw that it switched the WinUI to 3 version, which support Title Bar customization.

My question is how to modify this Title Bar?

How to change the color of title bar (to no be accent from user for example I want this title bar to be black.)

How to add icon?

How to add additional items like in other Win11 apps?User's image

How with WinUI 3 assign to your visual Myca style or Acryl?

I hope I will get answer onto how modify title bar since this is only topic that bothers me.

    Hello,

    Avoid posting multiple questions in a single thread in Q&A

    Let's focus on the first issue, you can open new threads for other issues.

    How to change the color of title bar (to no be accent from user for example I want this title bar to be black.)

    You can get the titlebar in the following ConfigureLifecycleEvents, then set the background color to black for titlebar, three button's background and the inactive status.

        public static class MauiProgram
        {
            public static MauiApp CreateMauiApp()
            {
                var builder = MauiApp.CreateBuilder();
                builder
                    .UseMauiApp<App>()
                   .ConfigureLifecycleEvents(events =>
                              {
    #if WINDOWS
                                  events.AddWindows(windowsLifecycleBuilder =>
                                  {
                                      windowsLifecycleBuilder.OnWindowCreated(window =>
                                      {
                                          var handle = WinRT.Interop.WindowNative.GetWindowHandle(window);
                                          var id = Microsoft.UI.Win32Interop.GetWindowIdFromWindow(handle);
                                          var appWindow = Microsoft.UI.Windowing.AppWindow.GetFromWindowId(id);
                                          var titleBar = appWindow.TitleBar;                                
                                          titleBar.BackgroundColor = Colors.Black.ToWindowsColor();
                                          titleBar.ButtonBackgroundColor = Colors.Black.ToWindowsColor();                                             
                                          titleBar.InactiveBackgroundColor = Colors.Black.ToWindowsColor();    
                                          titleBar.ButtonInactiveBackgroundColor = Colors.Black.ToWindowsColor();
    
    
                                      });
    #endif
                                  });
                              })
