Question

我的问题是：我有两种尺寸的窗口，它们根据CheckBox而变化。以下是问题的屏幕截图：

就像您看到的那样，我的应用程序以不正确的大小开始，但是当我更改复选框时，一切正常，窗口大小变为正常

我已经测试过在应用程序启动时将CheckBox设置为由后面的代码启动并且无法正常工作。

这是我的自定义windowstyle的XAML

    <Style x:Key="CustomWindowStyle" TargetType="{x:Type Window}">
        <Setter Property="shell:WindowChrome.WindowChrome">

如果我删除了自定义窗口样式，则可以正常工作，所以这是我所缺少的。

您可以通过从XAML中删除SizeToContent="WidthAndHeight"并在加载窗口后以编程方式设置SizeToContent来摆脱此行为：

public partial class Window_SelectConnection : Window
{
    public Window_SelectConnection()
    {
        InitializeComponent();
        Loaded += OnLoaded;
    }

    private void OnLoaded(object sender, RoutedEventArgs e)
    {
        SizeToContent = SizeToContent.WidthAndHeight;
        Loaded -= OnLoaded;
    }
}

您可能想要创建一个自定义窗口类来为您执行此操作：

public class CustomWindow : Window
{
    public CustomWindow()
    {
        Loaded += CustomWindow_Loaded;
    }

    private void CustomWindow_Loaded(object sender, RoutedEventArgs e)
    {
        SizeToContent = SizeToContent.WidthAndHeight;
        Loaded -= CustomWindow_Loaded;
    }
}

...并从此继承：

public partial class Window_SelectConnection : CustomWindow

<local:CustomWindow x:Class="STEP_QuickSound_UI.Window_SelectConnection" ...
