Strokes.StrokesAdded Event
Occurs when one or more Stroke objects are added to the Strokes collection.
Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)
Syntax
'Declaration
Public Event StrokesAdded As StrokesEventHandler
'Usage
Dim instance As Strokes
Dim handler As StrokesEventHandler
AddHandler instance.StrokesAdded, handler
public event StrokesEventHandler StrokesAdded
public:
event StrokesEventHandler^ StrokesAdded {
void add (StrokesEventHandler^ value);
void remove (StrokesEventHandler^ value);
}
JScript does not support events.
Remarks
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.
Examples
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
