Csharp 覆盖默认窗口最小化按钮逻辑

发布于09月04日

有什么方法可以覆盖默认的窗口最小化按钮逻辑吗？我需要它来添加window.Hide()到它，这样我的窗口将被隐藏的同时，它将被最小化.

我已经找到了this篇文章，但我正在努力让它与Windows中的窗口最小化逻辑挂钩.

这可用于隐藏和显示ViewModel中的窗口，例如:

private void OnShowHideWindow()
{
  var window = Application.Current?.MainPage?.Window;
  if (window == null)
  {
    return;
  }

  if (this.IsWindowVisible)
  {
    window.Hide();
  }
  else
  {
    window.Show();
  }
  this.IsWindowVisible = !this.IsWindowVisible;
}

推荐答案

为了进一步解释张的回答(顺便说一句，回答得很好)，你不需要那些介绍电话.如果您想要在您的应用程序中实现此功能，请将其放入App()中，然后像这样简单地完成:

using Microsoft.Maui.Platform;
#if WINDOWS
using Microsoft.UI.Windowing;
#endif
...
public App()
{
    InitializeComponent();
    Microsoft.Maui.Handlers.WindowHandler.Mapper.AppendToMapping(nameof(IWindow), (handler, view) =>
    {
#if WINDOWS
        var nativeWindow = handler.PlatformView;
        var appWindow = nativeWindow.GetAppWindow();
        if (appWindow is not null)
        {
            appWindow.Changed += (sender, args) =>
            {
                if (appWindow.Presenter is OverlappedPresenter overlappedPresenter)
                {
                    if (args.DidPresenterChange && overlappedPresenter.State == OverlappedPresenterState.Minimized)
                    {
                        appWindow.Hide();
                        Thread.Sleep(5000);
                        nativeWindow.Activate();
                    }
                }
            };
        }

#endif
    });

    MainPage = new AppShell();
}
