WPF hitTest на сам UserControl

В поиске:

void click()
{
    Pin pin = null;
    Vector2 mouse = Mouse.GetPosition(MainWindow.main).ToVector2();
    VisualTreeHelper.HitTest(MainWindow.main, PinHitFilter, PinHitResult, new PointHitTestParameters(mouse));
}
HitTestFilterBehavior PinHitFilter(DependencyObject o)
{
    if (o is Pin) return HitTestFilterBehavior.ContinueSkipChildren;
    return HitTestFilterBehavior.Continue;
}
HitTestResultBehavior PinHitResult(HitTestResult result)
{
    Pin pin = result.VisualHit as Pin;
    return HitTestResultBehavior.Stop;
}

В элементе:

protected override HitTestResult HitTestCore(PointHitTestParameters hitTestParameters)
{
    return new PointHitTestResult(this, hitTestParameters.HitPoint);
}

Так этот способ работает.
