StylusPointPropertyInfo Class
Assembly: PresentationCore (in presentationcore.dll)
XML Namespace: http://schemas.microsoft.com/winfx/2006/xaml/presentation
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 =
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";
