Represents a property stored in a StylusPoint.

Public Class StylusPointProperty

System_CAPS_pubmethodStylusPointProperty(Guid, Boolean)

Initializes a new instance of the StylusPointProperty class using the specified GUID.


This API supports the product infrastructure and is not intended to be used directly from your code. Initializes a new instance of the StylusPointProperty class, copying the specified StylusPointProperty.


Gets the GUID for the current StylusPointProperty.


Gets whether the StylusPointProperty represents a button on the stylus.


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


Creates a shallow copy of the current Object.(Inherited from Object.)


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 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
