Заметки

The event handler receives an argument of type InkOverlaySelectionMovingEventArgs that contains data about this event.

When you create an InkOverlaySelectionMovingEventHandler delegate, you identify the method that handles 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. For performance reasons, the default event interest is off but is turned on automatically if you add an event handler.

Примеры

In this example, an SelectionMoving event handler examines a selection before it has been moved. If the selection will be moved so that any of it is outside the bounds of the window, the event handler turns the selection red by changing the Color property of each selected Stroke object.

Private Sub mInkPicture_SelectionMoving(ByVal sender As Object, ByVal e As InkOverlaySelectionMovingEventArgs)
    If e.NewPixelRect.Left < 0 Or e.NewPixelRect.Top < 0 Or _
       e.NewPixelRect.Right > mInkPicture.ClientRectangle.Width Or _
        e.NewPixelRect.Bottom > mInkPicture.ClientRectangle.Height Then

        For Each stroke As Stroke In mInkPicture.Selection
            ' change the stroke color
            stroke.DrawingAttributes.Color = Color.Red
        Next

    End If
End Sub

private void mInkPicture_SelectionMoving(object sender, InkOverlaySelectionMovingEventArgs e)
{
    if (e.NewPixelRect.Left < 0 || e.NewPixelRect.Top < 0 ||
        e.NewPixelRect.Right > mInkPicture.ClientRectangle.Width ||
        e.NewPixelRect.Bottom > mInkPicture.ClientRectangle.Height)
    {
        foreach (Stroke stroke in mInkObject.Selection)
        {
            // change the stroke color
            stroke.DrawingAttributes.Color = Color.Red;
        }
    }
}
