Example

The following example creates a new InkAnalyzer and attaches the StrokesChanged event handler to the Strokes property on the InkCanvas, theInkCanvas.

theInkAnalyzer = New InkAnalyzer()

AddHandler theInkCanvas.Strokes.StrokesChanged, AddressOf Strokes_StrokesChanged

theInkAnalyzer = new InkAnalyzer();

theInkCanvas.Strokes.StrokesChanged += 
    new StrokeCollectionChangedEventHandler(Strokes_StrokesChanged);

The following example defines the Strokes_StrokesChanged event handler, which adds the strokes that have been added to theInkCanvas to theInkAnalyzer and removes the strokes that have been removed from theInkCanvas from theInkAnalyzer.

' This event occurs whenever a stroke is added, removed, or partially erased
' from the InkCanvas.
Sub Strokes_StrokesChanged(ByVal sender As Object, ByVal e As StrokeCollectionChangedEventArgs) 
    If e.Added.Count > 0 Then
        theInkAnalyzer.AddStrokes(e.Added)
    End If
    
    If e.Removed.Count > 0 Then
        theInkAnalyzer.RemoveStrokes(e.Removed)
    End If

End Sub 'Strokes_StrokesChanged

// This event occurs whenever a stroke is added, removed, or partially erased
// from the InkCanvas.
void Strokes_StrokesChanged(object sender, StrokeCollectionChangedEventArgs e)
{
    if (e.Added.Count > 0)
    {
        theInkAnalyzer.AddStrokes(e.Added);
    }

    if (e.Removed.Count > 0)
    {
        theInkAnalyzer.RemoveStrokes(e.Removed);
    }
}
