Voorbeelden
In het volgende voorbeeld wordt ervoor gezorgd dat de verzamelde styluspunten afkomstig zijn van hetzelfde StylusDevice. Dit voorbeeld maakt deel uit van het grotere voorbeeld in het RawStylusInput klasoverzicht.
// 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());
currentStylus = rawStylusInput.StylusDeviceId;
}
}
// Collect the points as the user draws the stroke.
protected override void OnStylusMove(RawStylusInput rawStylusInput)
{
// Check whether the stylus that started the stroke is the same, and
// that the element hasn't lost focus since the stroke began.
