Ejemplos

En el ejemplo siguiente se crea un StylusPointDescription objeto a partir de StylusPointCollection y se obtiene la información de cada StylusPointPropertyInfo uno de los elementos 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());
        descriptionStringWriter.WriteLine("  Res {0}", property.Resolution.ToString());
    }

    descriptionOutput.Text = descriptionStringWriter.ToString();
}

Private Sub WriteDescriptionInfo(ByVal points As StylusPointCollection) 

    Dim pointsDescription As StylusPointDescription = points.Description

    Dim properties As ReadOnlyCollection(Of StylusPointPropertyInfo) = _

    descriptionStringWriter.Write("Property Count:{0}", pointsDescription.PropertyCount.ToString())
    
    Dim pointProperty As StylusPointPropertyInfo
    For Each pointProperty In properties

        ' GetStylusPointPropertyName is defined below and returns the
        ' name of the property.
        descriptionStringWriter.Write("name = {0}", GetStylusPointPropertyName(pointProperty).ToString())
        descriptionStringWriter.WriteLine("  Guid = {0}", pointProperty.Id.ToString())
        descriptionStringWriter.Write("  IsButton = {0}", pointProperty.IsButton.ToString())

Comentarios

La StylusPointPropertyInfo clase hereda de la StylusPointProperty clase y genera los Minimumvalores , Maximum, Resolutiony Unit usados para definir las propiedades de .StylusPoint La validez de cada valor de propiedad varía según la fabricación del digitalizador y el lápiz óptico.

Constructores

StylusPointPropertyInfo(StylusPointProperty)	Inicializa una nueva instancia de la clase StylusPointPropertyInfo.
StylusPointPropertyInfo(StylusPointProperty, Int32, Int32, StylusPointPropertyUnit, Single)	Inicializa una nueva instancia de la clase StylusPointPropertyInfo mediante los valores especificados.

Propiedades

Id	Obtiene el GUID del objeto StylusPointProperty actual. (Heredado de StylusPointProperty)
IsButton	Obtiene si StylusPointProperty representa un botón del lápiz óptico. (Heredado de StylusPointProperty)
Maximum	Obtiene el valor máximo admitido en la propiedad StylusPoint.
Minimum	Obtiene el valor mínimo admitido en la propiedad StylusPoint.
