Ejemplos

En el ejemplo siguiente se garantiza que los puntos del lápiz óptico recopilados proceden de la misma StylusDevice. Este ejemplo forma parte del ejemplo más grande de la información general de la RawStylusInput clase.

// Collect the points as the user draws the stroke.
protected override void OnStylusDown(RawStylusInput rawStylusInput)
{
    // If points is not null, there is already a stroke taking place
    // on the digitizer, so don't create a new StylusPointsCollection.
    if (points == null)

        points = new StylusPointCollection(rawStylusInput.GetStylusPoints().Description);
        points.Add(rawStylusInput.GetStylusPoints());

    // that the element hasn't lost focus since the stroke began.
