StylusPointProperty Class

Represents a property stored in a StylusPoint.

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

Public Class StylusPointProperty

The StylusPointProperty type exposes the following members.

Protected methodStylusPointProperty(StylusPointProperty)Infrastructure. Initializes a new instance of the StylusPointProperty class, copying the specified StylusPointProperty.
Public methodStylusPointProperty(Guid, Boolean)Initializes a new instance of the StylusPointProperty class using the specified GUID.

Public propertyIdGets the GUID for the current StylusPointProperty.
Public propertyIsButtonGets whether the StylusPointProperty represents a button on the stylus.

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. (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 Sub WriteDescriptionInfo(ByVal points As StylusPointCollection) 

    Dim pointsDescription As StylusPointDescription = points.Description

    Dim properties As ReadOnlyCollection(Of StylusPointPropertyInfo) = _

    Dim descriptionStringWriter As New StringWriter
    descriptionStringWriter.Write("Property Count:{0}", pointsDescription.PropertyCount.ToString())

    Dim pointProperty As StylusPointPropertyInfo
    For Each pointProperty In properties

        ' GetStylusPointPropertyName is defined below and returns the 
        ' name of the property.
        descriptionStringWriter.Write("name = {0}", GetStylusPointPropertyName(pointProperty).ToString())
        descriptionStringWriter.WriteLine("  Guid = {0}", pointProperty.Id.ToString())
        descriptionStringWriter.Write("  IsButton = {0}", pointProperty.IsButton.ToString())
        descriptionStringWriter.Write("  Min = {0}", pointProperty.Minimum.ToString())
        descriptionStringWriter.Write("  Max = {0}", pointProperty.Maximum.ToString())
        descriptionStringWriter.Write("  Unit = {0}", pointProperty.Unit.ToString())
        descriptionStringWriter.WriteLine("  Res {0}", pointProperty.Resolution.ToString())

    Next pointProperty

    descriptionOutput.Text = descriptionStringWriter.ToString()

End Sub 'WriteDescriptionInfo


' Use reflection to get the name of currentProperty. 
Private Function GetStylusPointPropertyName(ByVal currentProperty As StylusPointProperty) As String  
    Dim guid As Guid = currentProperty.Id

    ' Iterate through the StylusPointProperties to find the StylusPointProperty 
    ' that matches currentProperty, then return the name. 
    Dim theFieldInfo As FieldInfo

    For Each theFieldInfo In GetType(StylusPointProperties).GetFields()

        Dim pointProperty As StylusPointProperty = _
            CType(theFieldInfo.GetValue(currentProperty), StylusPointProperty)

        If pointProperty.Id = guid Then 
            Return theFieldInfo.Name
        End If 

    Next theFieldInfo

    Return "Not found" 

End Function 'GetStylusPointPropertyName
