如何使我的 MAUI 应用程序的 window 固定，因此无法调整大小或设置最小高度/宽度？

Question

How can I set the size of the window in my MAUI Windows application to be fixed? So the user can not resize the window. Or how is it possible to set a minimum height or width to the window?

Answer 1

you can set OverlappedPresenter.IsResizable Property to false using handler api:

public App()
{
        InitializeComponent();
#if WINDOWS
        SetWinNoResizable();
#endif
...
}

    public void SetWinNoResizable()
    {
        Microsoft.Maui.Handlers.WindowHandler.Mapper.AppendToMapping(nameof(IWindow),
                                                                    (handler, view) =>
        {
#if WINDOWS
            var nativeWindow = handler.PlatformView;
            IntPtr windowHandle = WinRT.Interop.WindowNative.GetWindowHandle(nativeWindow);
            WindowId WindowId = Win32Interop.GetWindowIdFromWindow(windowHandle);
            AppWindow appWindow = AppWindow.GetFromWindowId(WindowId);
            var presenter = appWindow.Presenter as OverlappedPresenter;
            presenter.IsResizable = false;
#endif
        });
    }
