Ejemplos

El ejemplo siguiente muestra cómo recuperar el PointHitTestResult devolver valor de la HitTest método.The following example shows how to retrieve the PointHitTestResult return value from the HitTest method.

// Respond to the left mouse button down event by initiating the hit test.
private 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.
    }
}
' Respond to the left mouse button down event by initiating the hit test.
Private Overloads Sub OnMouseLeftButtonDown(ByVal sender As Object, ByVal e As MouseButtonEventArgs)
	' Retrieve the coordinate of the mouse position.
	Dim pt As Point = e.GetPosition(CType(sender, UIElement))

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

	If result IsNot Nothing Then
		' Perform action on hit visual object.
	End If
End Sub
