Remarques

Une StylusPointDescription spécifie les propriétés associées à un StylusPoint.A StylusPointDescription specifies which properties are associated with a StylusPoint. Pour chaque propriété d’un StylusPoint, le StylusPointDescription contient un StylusPointPropertyInfo objet qui spécifie des contraintes telles que les valeurs minimale et maximale de la propriété.For each property in a StylusPoint, the StylusPointDescription contains a StylusPointPropertyInfo object which specifies constraints such as the minimum and maximum values of the property. Utilisez les HasProperty méthodes GetPropertyInfo et pour vérifier ces propriétés dans le StylusPointDescription.Use the HasProperty and GetPropertyInfo methods to check for these properties in the StylusPointDescription.

Tous StylusPoint les objets d' StylusPointCollection un doivent partager le StylusPointDescriptionmême.All StylusPoint objects in a StylusPointCollection must share the same StylusPointDescription. Si vous essayez d’ajouter un StylusPoint à un StylusPointCollection qui a un différent StylusPointDescription, une exception est levée.If you try to add a StylusPoint to a StylusPointCollection that has a different StylusPointDescription, an exception will be thrown.
