如何在最大窗口中打开Maui项目

Question

当我们运行。net MAUI项目时，它将在最小化窗口中打开项目，但我想在最大化窗口中打开它。

我在代码中做了一些修改，使它在Windows平台上以最大化的窗口打开。

Answer 1

您可以使用WinUIEx NuGet包轻松实现此功能。

首先，安装winux在你的项目中。现在，我猜你需要安装v1.8.0。

然后添加这些WINDOWSMauiProgram.cs.

#if WINDOWS
using WinUIEx;
using Microsoft.Maui.LifecycleEvents;
#endif
namespace MauiApp1;
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 WINDOWS
builder.ConfigureLifecycleEvents(events =>
{
events.AddWindows(wndLifeCycleBuilder =>
{
wndLifeCycleBuilder.OnWindowCreated(window =>
{
window.Maximize();
});
});
});
#endif
return builder.Build();
}
}

Per [HELP]如何为应用程序窗口指定固定的大小?在Github上，您可以尝试像下面这样编辑您的MauiProgram.cs以在最大化窗口中打开。在Windows平台初始化应用程序时。

using Microsoft.Maui.LifecycleEvents;
#if WINDOWS
using Microsoft.UI;
using Microsoft.UI.Windowing;
using Windows.Graphics;
#endif
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 WINDOWS
builder.ConfigureLifecycleEvents(events =>
{
events.AddWindows(wndLifeCycleBuilder =>
{
wndLifeCycleBuilder.OnWindowCreated(window =>
{
IntPtr nativeWindowHandle = WinRT.Interop.WindowNative.GetWindowHandle(window);
WindowId win32WindowsId = Win32Interop.GetWindowIdFromWindow(nativeWindowHandle);
AppWindow winuiAppWindow = AppWindow.GetFromWindowId(win32WindowsId);
if(winuiAppWindow.Presenter is OverlappedPresenter p)
p.Maximize();
else
{
const int width = 1920;
const int height = 1080;
winuiAppWindow.MoveAndResize(new RectInt32(1920 / 2 - width / 2, 1080 / 2 - height / 2, width, height));
}
});
});
});
#endif
return builder.Build();
}
}
