StylusPointProperty Class
Represents a property stored in a StylusPoint.
Namespace: System.Windows.Input
Assembly: PresentationCore (in PresentationCore.dll)
The StylusPointProperty type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | StylusPointProperty(StylusPointProperty) | Infrastructure. Initializes a new instance of the StylusPointProperty class, copying the specified StylusPointProperty. |
![]() | StylusPointProperty(Guid, Boolean) | Initializes a new instance of the StylusPointProperty class using the specified GUID. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Overrides Object.ToString().) |
A StylusPointProperty represents properties in StylusPoint such as the (x, y) coordinates, pressure, and so on. You can inherit from the StylusPointProperty class to customize the information stored for each property. The Windows Presentation Framework ships with the StylusPointPropertyInfo class that inherits from StylusPointProperty and specifies the minimum and maximum values, resolution, and unit used for each property.
The following example creates the 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"; }
