Комментарии

Указывает, какие свойства связаны StylusPointс. StylusPointDescriptionA StylusPointDescription specifies which properties are associated with a StylusPoint. Для каждого свойства в StylusPoint StylusPointDescription объект содержит StylusPointPropertyInfo объект, указывающий ограничения, такие как минимальное и максимальное значения свойства.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. Используйте методы GetPropertyInfo StylusPointDescriptionи для проверки этих свойств в. HasPropertyUse the HasProperty and GetPropertyInfo methods to check for these properties in the StylusPointDescription.

Все StylusPoint объекты StylusPointDescriptionв должны совместно использоваться. StylusPointCollectionAll StylusPoint objects in a StylusPointCollection must share the same StylusPointDescription. При попытке добавить StylusPoint в объект StylusPointCollection , который имеет другое StylusPointDescriptionзначение, будет создано исключение.If you try to add a StylusPoint to a StylusPointCollection that has a different StylusPointDescription, an exception will be thrown.
