Примеры

В следующем примере StylusPointDescription создается объект StylusPointCollection из объекта и получается StylusPointDescriptionинформация для каждого StylusPointPropertyInfo из.The following example creates an StylusPointDescription object from a StylusPointCollection and gets the information for each StylusPointPropertyInfo in the StylusPointDescription.

private void WriteDescriptionInfo(StylusPointCollection points)
{
    StylusPointDescription pointsDescription = points.Description;
    ReadOnlyCollection<StylusPointPropertyInfo> properties = 
        pointsDescription.GetStylusPointProperties();

    StringWriter descriptionStringWriter = new StringWriter();
    descriptionStringWriter.Write("Property Count:{0}", pointsDescription.PropertyCount.ToString());
    
    foreach (StylusPointPropertyInfo property in properties)
    {
        // GetStylusPointPropertyName is defined below and returns the
        // name of the property.
        descriptionStringWriter.Write("name = {0}", GetStylusPointPropertyName(property).ToString());
        descriptionStringWriter.WriteLine("  Guid = {0}", property.Id.ToString());
        descriptionStringWriter.Write("  IsButton = {0}", property.IsButton.ToString());
        descriptionStringWriter.Write("  Min = {0}", property.Minimum.ToString());
        descriptionStringWriter.Write("  Max = {0}", property.Maximum.ToString());
        descriptionStringWriter.Write("  Unit = {0}", property.Unit.ToString());

Комментарии

Resolution Unit КласснаследуетStylusPointот класса и создает Minimumзначения, Maximum, и, используемые для определения свойств объекта. StylusPointProperty StylusPointPropertyInfoThe StylusPointPropertyInfo class inherits from the StylusPointProperty class and generates the Minimum, Maximum, Resolution, and Unit values used to define the properties of a StylusPoint. Допустимость каждого значения свойства зависит от производителя дигитайзера и пера.The validity of each property value varies depending on the manufacture of the digitizer and stylus.
