StylusPointPropertyUnit Enumeration

Specifies the unit of measurement for a StylusPoint property.

Namespace:  System.Windows.Input
Assembly:  PresentationCore (in PresentationCore.dll)

public enum StylusPointPropertyUnit
<object property="enumerationMemberName" .../>

Member nameDescription
CentimetersIndicates that a StylusPoint property is measured in centimeters.
DegreesIndicates that a StylusPoint property is measured in degrees.
GramsIndicates that a StylusPoint property is measured in grams.
InchesIndicates that a StylusPoint property is measured in inches.
NoneIndicates that a StylusPoint property's measurement is not specified.
PoundsIndicates that a StylusPoint property is measured in pounds.
RadiansIndicates that a StylusPoint property is measured in radians.
SecondsIndicates that a StylusPoint property is measured in seconds.

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());
        descriptionStringWriter.WriteLine("  Res {0}", property.Resolution.ToString());
    }

    descriptionOutput.Text = descriptionStringWriter.ToString();
}


...


// Use reflection to get the name of currentProperty. 
private string GetStylusPointPropertyName(StylusPointProperty currentProperty)
{
    Guid guid = currentProperty.Id;

    // Iterate through the StylusPointProperties to find the StylusPointProperty 
    // that matches currentProperty, then return the name. 
    foreach (FieldInfo theFieldInfo
        in typeof(StylusPointProperties).GetFields())
    {
        StylusPointProperty property = (StylusPointProperty) theFieldInfo.GetValue(currentProperty);
        if (property.Id == guid)
        {
            return theFieldInfo.Name;
        }
    }
    return "Not found";
