StylusPointPropertyInfo Class
Specifies the constraints of a property in a StylusPoint.
Assembly: PresentationCore (in PresentationCore.dll)
The StylusPointPropertyInfo type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | StylusPointPropertyInfo(StylusPointProperty) | Initializes a new instance of the StylusPointPropertyInfo class. |
![]() | StylusPointPropertyInfo(StylusPointProperty, Int32, Int32, StylusPointPropertyUnit, Single) | Initializes a new instance of the StylusPointPropertyInfo class using the specified values. |
| Name | Description | |
|---|---|---|
![]() | Id | Gets the GUID for the current StylusPointProperty. (Inherited from StylusPointProperty.) |
![]() | IsButton | Gets whether the StylusPointProperty represents a button on the stylus. (Inherited from StylusPointProperty.) |
![]() | Maximum | Gets the maximum value accepted for the StylusPoint property. |
![]() | Minimum | Gets the minimum value accepted for the StylusPoint property. |
![]() | Resolution | Gets the scale that converts a StylusPoint property value into units. |
![]() | Unit | Gets the type of measurement that is used by StylusPoint property. |
| 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. (Inherited from StylusPointProperty.) |
The StylusPointPropertyInfo class inherits from the StylusPointProperty class and generates the Minimum, Maximum, Resolution, and Unit values used to define the properties of a StylusPoint. The validity of each property value 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 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
