StylusPointCollection()

Initializes a new instance of the StylusPointCollection class.

public:
 StylusPointCollection();

public StylusPointCollection ();

Public Sub New ()

The following example collects StylusPoint objects in the OnStylusDown method of a custom control. The example creates a StylusPointCollection by specifying the StylusPointDescription and the initial size of the StylusPointCollection.

StylusPointCollection stylusPoints;

protected override void OnStylusDown(StylusDownEventArgs e)
{
    base.OnStylusDown(e);

    StylusPointCollection eventPoints = e.GetStylusPoints(this);

    // Create a new StylusPointCollection using the StylusPointDescription
    // from the stylus points in the StylusDownEventArgs.
    stylusPoints = new StylusPointCollection(eventPoints.Description, eventPoints.Count);
    stylusPoints.Add(eventPoints);

The following example collects StylusPoint objects in the OnStylusDown method of a custom control. The example creates a StylusPointCollection by specifying both the StylusPointDescription and the initial size of the StylusPointCollection.

StylusPointCollection stylusPoints;

protected override void OnStylusDown(StylusDownEventArgs e)
{
    base.OnStylusDown(e);

    StylusPointCollection eventPoints = e.GetStylusPoints(this);

    // Create a new StylusPointCollection using the StylusPointDescription
    // from the stylus points in the StylusDownEventArgs.
    stylusPoints = new StylusPointCollection(eventPoints.Description, eventPoints.Count);
    stylusPoints.Add(eventPoints);
}

Private stylusPoints As StylusPointCollection


Protected Overrides Sub OnStylusDown(ByVal e As StylusDownEventArgs) 
    MyBase.OnStylusDown(e)
    
    Dim eventPoints As StylusPointCollection = e.GetStylusPoints(Me)
    
    ' Create a new StylusPointCollection using the StylusPointDescription
    ' from the stylus points in the StylusDownEventArgs.
    stylusPoints = New StylusPointCollection(eventPoints.Description, eventPoints.Count)
    stylusPoints.Add(eventPoints)

End Sub

Remarks

When you use the StylusPointCollection constructor to create a new StylusPointCollection, you specify it's initialCapacity. However, you can add more StylusPoint objects by calling the Add method.

Applies to

StylusPointCollection(StylusPointDescription)

Initializes a new instance of the StylusPointCollection class that contains the properties specified in the StylusPointDescription.

public:
 StylusPointCollection(System::Windows::Input::StylusPointDescription ^ stylusPointDescription);

public StylusPointCollection (System.Windows.Input.StylusPointDescription stylusPointDescription);

Public Sub New (stylusPointDescription As StylusPointDescription)

Parameters

stylusPointDescription: StylusPointDescription

A StylusPointDescription that specifies the additional properties stored in each StylusPoint.

Exceptions

ArgumentNullException

stylusPointDescription is null.

Examples

StylusPointCollection stylusPoints;

protected override void OnStylusDown(StylusDownEventArgs e)
{
    base.OnStylusDown(e);

    StylusPointCollection eventPoints = e.GetStylusPoints(this);

    // Create a new StylusPointCollection using the StylusPointDescription
    // from the stylus points in the StylusDownEventArgs.
    stylusPoints = new StylusPointCollection(eventPoints.Description, eventPoints.Count);
    stylusPoints.Add(eventPoints);
}

Private stylusPoints As StylusPointCollection


Protected Overrides Sub OnStylusDown(ByVal e As StylusDownEventArgs) 
    MyBase.OnStylusDown(e)
    
    Dim eventPoints As StylusPointCollection = e.GetStylusPoints(Me)
    
    ' Create a new StylusPointCollection using the StylusPointDescription
    ' from the stylus points in the StylusDownEventArgs.
    stylusPoints = New StylusPointCollection(eventPoints.Description, eventPoints.Count)
    stylusPoints.Add(eventPoints)

End Sub

Remarks

All StylusPoint objects added to the StylusPointCollection must have a StylusPointDescription that is compatible with stylusPointDescription.

Applies to

StylusPointCollection(StylusPointDescription, Int32)

Initializes a new instance of the StylusPointCollection class that is the specified size and contains the properties specified in the StylusPointDescription.

public:
 StylusPointCollection(System::Windows::Input::StylusPointDescription ^ stylusPointDescription, int initialCapacity);

public StylusPointCollection (System.Windows.Input.StylusPointDescription stylusPointDescription, int initialCapacity);

new System.Windows.Input.StylusPointCollection : System.Windows.Input.StylusPointDescription * int -> System.Windows.Input.StylusPointCollection

Public Sub New (stylusPointDescription As StylusPointDescription, initialCapacity As Integer)

Parameters

stylusPointDescription: StylusPointDescription

A StylusPointDescription that specifies the additional properties stored in each StylusPoint.

initialCapacity: Int32

The number of StylusPoint objects the StylusPointCollection can initially contain.

Exceptions

ArgumentException

initialCapacity is negative.

ArgumentNullException

stylusPointDescription is null.

Examples

StylusPointCollection stylusPoints;

protected override void OnStylusDown(StylusDownEventArgs e)
{
    base.OnStylusDown(e);

    StylusPointCollection eventPoints = e.GetStylusPoints(this);

    // Create a new StylusPointCollection using the StylusPointDescription
    // from the stylus points in the StylusDownEventArgs.
    stylusPoints = new StylusPointCollection(eventPoints.Description, eventPoints.Count);
    stylusPoints.Add(eventPoints);
}

Private stylusPoints As StylusPointCollection


Protected Overrides Sub OnStylusDown(ByVal e As StylusDownEventArgs) 
    MyBase.OnStylusDown(e)
    
    Dim eventPoints As StylusPointCollection = e.GetStylusPoints(Me)
    
    ' Create a new StylusPointCollection using the StylusPointDescription
    ' from the stylus points in the StylusDownEventArgs.
    stylusPoints = New StylusPointCollection(eventPoints.Description, eventPoints.Count)
    stylusPoints.Add(eventPoints)

End Sub

Remarks

When you use the StylusPointCollection constructor to create a new StylusPointCollection, the StylusPointCollection is created with the capacity to hold the specified number of StylusPoint objects. You can add more StylusPoint objects than initialCapacity by calling the Add method.
