Exemples

L’exemple suivant montre comment obtenir les informations sur une propriété à partir d’un StylusPointDescription. Cet exemple suppose que l’événement StylusMove a été connecté au gestionnaire d’événements ci-dessous.

void inkCanvas1_StylusMove(object sender, StylusEventArgs e)
{
    StylusPointCollection points = e.GetStylusPoints(inkCanvas1);
    StylusPointDescription description = points.Description;
    StringWriter normalPressureInfo = new StringWriter();

    if (description.HasProperty(StylusPointProperties.NormalPressure))
    {
        StylusPointPropertyInfo propertyInfo = 
            description.GetPropertyInfo(StylusPointProperties.NormalPressure);

        normalPressureInfo.WriteLine("  Guid = {0}", propertyInfo.Id.ToString());
        normalPressureInfo.Write("  Min = {0}", propertyInfo.Minimum.ToString());
        normalPressureInfo.Write("  Max = {0}", propertyInfo.Maximum.ToString());
        normalPressureInfo.Write("  Unit = {0}", propertyInfo.Unit.ToString());
        normalPressureInfo.WriteLine("  Res = {0}", propertyInfo.Resolution.ToString());
    }
}

Private Sub inkCanvas1_StylusMove(ByVal sender As Object, ByVal e As StylusEventArgs)
    Dim points As StylusPointCollection = e.GetStylusPoints(inkCanvas1)
    Dim description As StylusPointDescription = points.Description
    Dim normalPressureInfo As New StringWriter()

    If description.HasProperty(StylusPointProperties.NormalPressure) Then

        Dim propertyInfo As StylusPointPropertyInfo = _
            description.GetPropertyInfo(StylusPointProperties.NormalPressure)

        normalPressureInfo.WriteLine("  Guid = {0}", propertyInfo.Id.ToString())
        normalPressureInfo.Write("  Min = {0}", propertyInfo.Minimum.ToString())
        normalPressureInfo.Write("  Max = {0}", propertyInfo.Maximum.ToString())
        normalPressureInfo.Write("  Unit = {0}", propertyInfo.Unit.ToString())
        normalPressureInfo.WriteLine("  Res = {0}", propertyInfo.Resolution.ToString())
    End If

End Sub
