C# WPF - 点击图像

Question

我在 .NET 8 上有一个 WPF 应用程序，其中的窗口加载如下：

var myWindow = new Window
{
    WindowStyle = WindowStyle.None,
    AllowsTransparency = true,
    Background = Brushes.Transparent,
    WindowState = WindowState.Maximized,
    Topmost = true,
    ShowInTaskbar = false
};

myWindow.Show();

此后，

.png

文件将加载到

myWindow

的内容中

myImage = new Image
{
    Source = new BitmapImage(new Uri("./Resources/myImage.png", UriKind.Relative)),
    HorizontalAlignment = HorizontalAlignment.Center,
    VerticalAlignment = VerticalAlignment.Center,
    Width = 50,
    Height = 50,
    Opactity = 0.5,
    Cursor = System.Windows.Input.Cursors.None,
    IsHitTestVisible = false
};

myWindow.Content = myImage;

我需要做的是点击图像（图像应该被忽略）。

当前图像会阻止图像后面任何图层的所有点击。

IsHitTestVisible = false

这里好像不行...

Answer 1

要允许点击穿过图像并与其后面的图层交互，可以将 Image 的 IsHitTestVisible 属性设置为 false。但是，就您而言，该属性似乎未按预期工作。

var myWindow = new Window
{
    WindowStyle = WindowStyle.None,
    AllowsTransparency = true,
    Background = Brushes.Transparent,
    WindowState = WindowState.Maximized,
    Topmost = true,
    ShowInTaskbar = false,
    IsHitTestVisible = false  // Set IsHitTestVisible to false for the entire window
};

myWindow.Show();

var myImage = new Image
{
    Source = new BitmapImage(new Uri("./Resources/myImage.png", UriKind.Relative)),
    HorizontalAlignment = HorizontalAlignment.Center,
    VerticalAlignment = VerticalAlignment.Center,
    Width = 50,
    Height = 50,
    Opacity = 0.5,
    Cursor = System.Windows.Input.Cursors.None,
    IsHitTestVisible = true  // Set IsHitTestVisible to true for the image
};

myWindow.Content = myImage;
