Contoh

Contoh berikut menunjukkan cara mengembalikan elemen yang berada di bawah kursor. Synchronize Panggilan memastikan bahwa DirectlyOver mengembalikan elemen yang benar.

void AnimateButton()
{
    TranslateTransform buttonTransform = new TranslateTransform(0, 0);
    button1.RenderTransform = buttonTransform;

    // Animate the Button's position.
    DoubleAnimation myDoubleAnimation = new DoubleAnimation();
    myDoubleAnimation.From = 0;
    myDoubleAnimation.By = 100;
    myDoubleAnimation.Duration = new Duration(TimeSpan.FromSeconds(5));
    myDoubleAnimation.AutoReverse = true;
    myDoubleAnimation.RepeatBehavior = RepeatBehavior.Forever;

    buttonTransform.BeginAnimation(TranslateTransform.XProperty, myDoubleAnimation);       
}

Sub AnimateButton() 
    Dim buttonTransform As New TranslateTransform(0, 0)
    button1.RenderTransform = buttonTransform
    
    ' Animate the Button's position.
    Dim myDoubleAnimation As New DoubleAnimation()
    myDoubleAnimation.From = 0
    myDoubleAnimation.By = 100
    myDoubleAnimation.Duration = New Duration(TimeSpan.FromSeconds(5))
    myDoubleAnimation.AutoReverse = True
    myDoubleAnimation.RepeatBehavior = RepeatBehavior.Forever
    
    buttonTransform.BeginAnimation(TranslateTransform.XProperty, myDoubleAnimation)

End Sub

void SynchronizeCurrentStylus()
{
    StylusDevice currentStylus = Stylus.CurrentStylusDevice;

    currentStylus.Synchronize();
    UIElement element = (UIElement) currentStylus.DirectlyOver;
    output.Text += "The stylus is over " + element.ToString() + "\r\n";
}

Sub SynchronizeCurrentStylus()

    Dim currentStylus As StylusDevice = Stylus.CurrentStylusDevice

    currentStylus.Synchronize()
    Dim element As UIElement = CType(currentStylus.DirectlyOver, UIElement)
    output.Text += "The stylus is over " + element.ToString() + vbCr + vbLf

End Sub

Keterangan

Aplikasi mungkin perlu menemukan elemen tempat kursor diposisikan. Jika aplikasi menggunakan animasi, DirectlyOver metode mungkin mengembalikan elemen yang telah dipindahkan dari bawah kursor. Panggil Synchronize untuk memastikan bahwa DirectlyOver mengembalikan elemen yang tepat.
