StylusPointPropertyInfo Class
Specifies the constraints of a property in a StylusPoint.
Assembly: PresentationCore (in PresentationCore.dll)
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"; }
