Specifies the constraints of a property in a StylusPoint.

System.Object
  System.Windows.Input.StylusPointProperty
    System.Windows.Input.StylusPointPropertyInfo

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

public class StylusPointPropertyInfo : StylusPointProperty

The StylusPointPropertyInfo type exposes the following members.

  NameDescription
Public methodStylusPointPropertyInfo(StylusPointProperty)Initializes a new instance of the StylusPointPropertyInfo class.
Public methodStylusPointPropertyInfo(StylusPointProperty, Int32, Int32, StylusPointPropertyUnit, Single)Initializes a new instance of the StylusPointPropertyInfo class using the specified values.

  NameDescription
Public propertyIdGets the GUID for the current StylusPointProperty. (Inherited from StylusPointProperty.)
Public propertyIsButtonGets whether the StylusPointProperty represents a button on the stylus. (Inherited from StylusPointProperty.)
Public propertyMaximumGets the maximum value accepted for the StylusPoint property.
Public propertyMinimumGets the minimum value accepted for the StylusPoint property.
Public propertyResolutionGets the scale that converts a StylusPoint property value into units.
Public propertyUnitGets the type of measurement that is used by StylusPoint property.

  NameDescription
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from StylusPointProperty.)

The StylusPointPropertyInfo class inherits from the StylusPointProperty class and generates the Minimum, Maximum, Resolution, and Unit values used to define the properties of a StylusPoint. The validity of each property value 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 = 
        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";
}
