StylusPointPropertyInfo Class

Specifies the constraints of a property in a StylusPoint.

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

public class StylusPointPropertyInfo : StylusPointProperty
public class StylusPointPropertyInfo extends StylusPointProperty
public class StylusPointPropertyInfo extends StylusPointProperty
You cannot use this managed class in XAML.

The StylusPointPropertyInfo class inherits from the StylusPointProperty class and generates the Minimum, Maximum, Resolution, and Unit values used for a property in a StylusPoint. The valid information for each property varies depending on the manufacture of the digitizer and stylus.

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 = 

        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";
