This class is abstract; see Inheritance Hierarchy for derived non-abstract classes usable in XAML.

The PointHitTestResult, GeometryHitTestResult, and RayHitTestResult classes derive from HitTestResult.

The following example shows how to retrieve the HitTestResult return value from the HitTest method.

// Respond to the left mouse button down event by initiating the hit test.
public void OnMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    // Retrieve the coordinate of the mouse position.
    Point pt = e.GetPosition((UIElement)sender);

    // Perform the hit test against a given portion of the visual object tree.
    HitTestResult result = VisualTreeHelper.HitTest(myCanvas, pt);

    if (result != null)
    {
        // Perform action on hit visual object.
    }
}

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
