Gets the bounding rectangle of the selected Strokes collection as it existed before the SelectionResized event fired.

Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in microsoft.ink.dll)

Syntax

'Declaration
Public ReadOnly Property OldSelectionBoundingRect As Rectangle
'Usage
Dim instance As InkOverlaySelectionResizedEventArgs
Dim value As Rectangle

value = instance.OldSelectionBoundingRect

public Rectangle OldSelectionBoundingRect { get; }

public:
property Rectangle OldSelectionBoundingRect {
    Rectangle get ();
}

/** @property */
public Rectangle get_OldSelectionBoundingRect ()

public function get OldSelectionBoundingRect () : Rectangle

Not applicable.

Property Value

The size of the selected Strokes collection as it existed before the SelectionResized event fired.

Remarks

The OldSelectionBoundingRect property provides specific information about the InkOverlaySelectionResizedEventArgs event.

Note

This rectangle is specified in ink space coordinates, which allows for undo scenarios.

Example

This C# example creates an event handler, theInkOverlay_SelectionMoved, that affects a selection after it has been resized. If the selected Strokes collection has been resized so that either dimension is smaller than 500 HIMETRIC units, the event handler restores that selection to its previous size.

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 too small
       if (newBounds.Height < 500 || newBounds.Width < 500)
       {
           // Resize to back to original rectangle
           theInkOverlay.Selection.ScaleToRectangle(e.OldSelectionBoundingRect);

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