Syntax

'Declaration

    synchronizingObject As Dispatcher _
)
'Usage
Dim synchronizingObject As Dispatcher 

Dim instance As New InkAnalyzer(synchronizingObject)

public InkAnalyzer(
    Dispatcher synchronizingObject
)

InkAnalyzer(
    Dispatcher^ synchronizingObject

Examples

The following example creates a new InkAnalyzer and attaches the StrokesChanged event handler to the Strokes property on the InkCanvas, named 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 strokes to theInkAnalyzer if they were already been added to theInkCanvas. It also removes strokes from theInkAnalyzer if they were already removed from theInkCanvas.

' 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);
    }
}
