Property Value

The bounding rectangle of the selected Strokes collection as it existed before the SelectionMoved event fired.

Remarks

The OldSelectionBoundingRect property gets the position that the selected Strokes collection was located in before the SelectionMoved event fired.

Example

This C# example creates an event handler, theInkOverlay_SelectionMoved, that affects a selection after it has been moved. If the selected Strokes collection has been moved so that any part of the collection is positioned outside the left or top boundaries of the InkOverlay object, theInkOverlay, the event handler moves the selection back to its original position.

using Microsoft.Ink;
//...
  theInkOverlay.SelectionMoved += new InkOverlaySelectionMovedEventHandler(theInkOverlay_SelectionMoved);
//...
  private void theInkOverlay_SelectionMoved(object sender, InkOverlaySelectionMovedEventArgs e)
  {
       Rectangle newBounds = theInkOverlay.Selection.GetBoundingBox();
       // Check if the selection is positioned outside the left or top boundaries 
       // of the window.
       if (newBounds.Left < 0 || newBounds.Top < 0)
       {
           // Move to back to original location
           theInkOverlay.Selection.Move(e.OldSelectionBoundingRect.Left - newBounds.Left,
               e.OldSelectionBoundingRect.Top - newBounds.Top);

           // Trick to insure that selection handles are updated
           theInkOverlay.Selection = theInkOverlay.Selection;
       }
   }
//...
