StylusPointPropertyUnit Enumeration

Specifies the unit of measurement for a StylusPoint property.

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

'Declaration
Public Enumeration StylusPointPropertyUnit
<object property="enumerationMemberName" .../>

Member nameDescription
NoneIndicates that a StylusPoint property's measurement is not specified.
InchesIndicates that a StylusPoint property is measured in inches.
CentimetersIndicates that a StylusPoint property is measured in centimeters.
DegreesIndicates that a StylusPoint property is measured in degrees.
RadiansIndicates that a StylusPoint property is measured in radians.
SecondsIndicates that a StylusPoint property is measured in seconds.
PoundsIndicates that a StylusPoint property is measured in pounds.
GramsIndicates that a StylusPoint property is measured in grams.

The following example creates an 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) = _
        pointsDescription.GetStylusPointProperties()

    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
