Last time, maybe 1 or 2 month ago, I asked some questions about how to use customized behavior class to move selected shape/shapes. One of question is when user is moving a selected shape then should show handler rectangles. Because I insert a tracker node to show user how selected shape is being moved. That time you told me use DrawForeground event to show there rectangles. But there is a problem, see the picture:



There rectangles can not be show completely, how to solve this problem?
Thanks a lot.
