Stylus.Synchronize Method

Synchronizes the cursor and the user interface.

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

'Declaration
Public Shared Sub Synchronize

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.

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 'AnimateButton


...


Sub SynchronizeStylus()

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

End Sub 'SynchronizeStylus
