wpf - 如何制作具有默认标题栏功能的透明 WPF 窗口？

Question

我正在使用 WPF 编写一个小应用程序。我想让窗口的内部位透明，带有不透明的控件，而标题栏(以及移动、最小化、最大化、调整大小、关闭等的能力)保持稳定。

但是由于某种原因，WPF 不允许我在将 AllowTransparency 设置为 true 时使用默认标题栏，这迫使我将 WindowStyle 设置为 None，这不是我想要的。有解决方法吗？

我的应用程序和问题并不是那么先进，以至于从头开始是一个问题。

要实现窗口透明，需要设置如下

WindowStartupLocation="CenterScreen"
AllowsTransparency ="True"
WindowStyle="None"
Background="Transparent"

最大化、最小化、关闭都可以自己实现:

XAML:

  <Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="30"></RowDefinition>
        <RowDefinition></RowDefinition>
    </Grid.RowDefinitions>
    <Rectangle Fill="Brown" MouseLeftButtonDown="Rectangle_MouseLeftButtonDown"></Rectangle>
    <WrapPanel HorizontalAlignment="Right" VerticalAlignment="Top" Height="30" Width="Auto">
        <Button Width="20" Height="20" Margin="5" Click="Button_Click_1">_</Button>
        <Button Width="20" Height="20" Margin="5" Click="Button_Click_2">口</Button>
        <Button Width="20" Height="20" Margin="5" Click="Button_Click_3">X</Button>
    </WrapPanel>
</Grid>

代码:

    /// <summary>
    /// Min
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    private void Button_Click_1(object sender, RoutedEventArgs e)
    {
        if (this.WindowState != WindowState.Minimized)
        {
            this.WindowState = WindowState.Minimized;
        }
    }

    /// <summary>
    /// Max
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    private void Button_Click_2(object sender, RoutedEventArgs e)
    {
        if (this.WindowState != WindowState.Maximized)
        {
            this.WindowState = WindowState.Normal;
        }
    }

    /// <summary>
    /// Close
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    private void Button_Click_3(object sender, RoutedEventArgs e)
    {
        this.Close();
    }

    /// <summary>
    /// DragMove
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    private void Rectangle_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
    {
        this.DragMove();
    }
