DynamicRenderer Constructor (IntPtr)

Článek
10/19/2012

Initializes a new instance of the DynamicRenderer class.

Namespace: Microsoft.StylusInput
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)

Syntax

'Declaration
Public Sub New ( _
    handle As IntPtr _
)
'Usage
Dim handle As IntPtr 

Dim instance As New DynamicRenderer(handle)

public DynamicRenderer(
    IntPtr handle
)

public:
DynamicRenderer(
    IntPtr handle
)

public function DynamicRenderer(
    handle : IntPtr
)

Parameters

handle
Type: System.IntPtr

The control on which the tablet pen data is displayed.

Remarks

Although you typically initialize the DynamicRenderer and RealTimeStylus objects with the same Control or window handle, it is possible to initialize them with different objects. An example of this is when you want to render the ink in a different window than where the stroke packet are generated.

Examples

This C# example shows the event handler for the Load event for a form that implements the IStylusAsyncPlugin interface. A new instance of a DynamicRenderer object, theDynamicRenderer, and a RealTimeStylus object, theRealTimeStylus, are initialized, associated with the form, and enabled.

using Microsoft.StylusInput;
// ...
private RealTimeStylus theRealTimeStylus;
private DynamicRenderer theDynamicRenderer;
// ...
private void InkCollection_Load(object sender, System.EventArgs e)
{
    theDynamicRenderer = new DynamicRenderer(Handle);
    theRealTimeStylus = new RealTimeStylus(this, true);

    // Add the dynamic renderer to the synchronous plugin notification chain.
    // Synchronous notifications occur on the pen thread.
    theRealTimeStylus.SyncPluginCollection.Add(theDynamicRenderer);

    // Add the form to the asynchronous plugin notification chain.  This plugin
    // will be used to collect stylus data into an ink object.  Asynchronous
    // notifications occur on the UI thread.
    theRealTimeStylus.AsyncPluginCollection.Add(this);

    // Enable the real time stylus and the dynamic renderer
    theRealTimeStylus.Enabled = true;
    theDynamicRenderer.Enabled = true;  
}

This Microsoft Visual Basic .NET example shows the event handler for the Load event for a form that implements the IStylusAsyncPlugin interface. A new instance of a DynamicRenderer object, theDynamicRenderer, and a RealTimeStylus object, theRealTimeStylus, are initialized, associated with the form, and enabled.

Imports Microsoft.StylusInput
' ...
Private theRealTimeStylus As RealTimeStylus
Private theDynamicRenderer As DynamicRenderer

' ...
Private Sub InkCollector_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles MyBase.Load
    theDynamicRenderer = New DynamicRenderer(Handle)
    theRealTimeStylus = New RealTimeStylus(Me, True)

    ' Add the dynamic renderer to the synchronous plugin notification chain.
    ' Synchronous notifications occur on the pen thread.
    theRealTimeStylus.SyncPluginCollection.Add(theDynamicRenderer)

    ' Add the form to the asynchronous plugin notification chain.  This plugin
    ' will be used to collect stylus data into an ink object.  Asynchronous
    ' notifications occur on the UI thread.
    theRealTimeStylus.AsyncPluginCollection.Add(Me)

    ' Enable the real time stylus and the dynamic renderer
    theRealTimeStylus.Enabled = True
    theDynamicRenderer.Enabled = True
End Sub
