StylusPointPropertyInfo 類別

定義

指定 StylusPoint 中屬性的條件約束 (Constraint)。

public ref class StylusPointPropertyInfo : System::Windows::Input::StylusPointProperty
public class StylusPointPropertyInfo : System.Windows.Input.StylusPointProperty
type StylusPointPropertyInfo = class

範例

下列範例會StylusPointDescriptionStylusPointCollection 建立物件,並取得 中StylusPointDescription每個 StylusPointPropertyInfo 的資訊。

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());

備註

類別StylusPointPropertyInfo繼承自 StylusPointProperty 類別,併產生MaximumMinimum、、 ResolutionUnit 值,用來定義 的屬性StylusPoint。 每個屬性值的有效性會根據數位板和手寫筆的製造而有所不同。
