Strokes.StrokesAdded Event
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)
The event handler receives an argument of type StrokesEventArgs containing data about this event.
When you create a StrokesEventHandler delegate, you identify the method handling the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate.
In this example, a StrokesAdded event handler rotates newly added strokes clockwise 90 degrees. The rotation occurs around the center of the bounding box of the newly added Stroke object.
' Reminder: To avoid a memory leak, you must explicitly call the Dispose() method ' on any Strokes collection to which an event handler has been attached before ' the collection goes out of scope. Private Sub Strokes_StrokesAdded(ByVal sender As Object, ByVal e As StrokesEventArgs) ' check each stroke id passed to the handler For Each id As Integer In e.StrokeIds ' find the Stroke For Each oneStroke As Stroke In DirectCast(sender, Strokes) ' when we find the added stroke, rotate it If (oneStroke.Id = id) Then Dim bounds As Rectangle = oneStroke.GetBoundingBox() ' create a point at the center of bounding box Dim center As Point = New Point(bounds.Left + (bounds.Width / 2), bounds.Top + (bounds.Height / 2)) ' rotate the stroke oneStroke.Rotate(90, center) End If Next Next End Sub
