Article

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

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

Syntax

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

value = instance.OldSelectionBoundingRect

public Rectangle OldSelectionBoundingRect { get; }

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

public function get OldSelectionBoundingRect () : Rectangle

Property Value

Type: System.Drawing.Rectangle
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.

Examples

In this example, an SelectionMoved event handler examines a selection after it has been moved. If the selected Strokes collection is moved so that any of the selection is off the left or top side of the window, then the selection is moved back to its original position.

Private Sub mInkObject_SelectionMoved(ByVal sender As Object, ByVal e As InkOverlaySelectionMovedEventArgs)
    ' mInkObject can be InkOverlay or InkPicture 
    Dim newBounds As Rectangle = mInkObject.Selection.GetBoundingBox()
    ' Check if we have gone off the left or top sides of the window. 
    If (newBounds.Left < 0 Or newBounds.Top < 0) Then 
        ' Move to back to original spot
        mInkObject.Selection.Move(e.OldSelectionBoundingRect.Left - newBounds.Left, _
            e.OldSelectionBoundingRect.Top - newBounds.Top)
        ' Trick to insure that selection handles are updated
        mInkObject.Selection = mInkObject.Selection
    End If 
End Sub

private void mInkObject_SelectionMoved(object sender, InkOverlaySelectionMovedEventArgs e)
{
    // mInkObject can be InkOverlay or InkPicture
    Rectangle newBounds = mInkObject.Selection.GetBoundingBox();

    // Check if we have gone off the left or top sides of the window. 
    if (newBounds.Left < 0 || newBounds.Top < 0)
    {
        // Move to back to original spot
        mInkObject.Selection.Move(e.OldSelectionBoundingRect.Left - newBounds.Left,
            e.OldSelectionBoundingRect.Top - newBounds.Top);

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