Stylus.Synchronize Method

Synchronizes the cursor and the user interface.

Namespace: System.Windows.Input
Assembly: PresentationCore (in presentationcore.dll)

public static void Synchronize ()
public static void Synchronize ()
public static function Synchronize ()
You cannot use methods in XAML.

Applications may need to determine the element on which the cursor is located. If the application uses animation, the DirectlyOver method might return an element that has moved out from under the cursor. Call Synchronize to be sure that DirectlyOver returns the proper element.

The following example demonstrates how to get the element that is under the cursor. Calling Synchronize ensures that DirectlyOver returns the correct element.

    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);       
  
    }

...

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