Článek

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 ();
}

public function get OldSelectionBoundingRect () : Rectangle

Property Value

Type: System.Drawing.Rectangle
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.

Examples

In this example, an SelectionResized event handler examines 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 selection is restored to its original size.

Private Sub mInkObject_SelectionResized(ByVal sender As Object, ByVal e As InkOverlaySelectionResizedEventArgs)
    Dim newBounds As Rectangle = mInkObject.Selection.GetBoundingBox()
    ' Check if we are too small 
    If (newBounds.Height < 500 Or newBounds.Width < 500) Then 
        ' Resize to back to original rectangle
        mInkObject.Selection.ScaleToRectangle(e.OldSelectionBoundingRect)

        ' Trick to insure that selection handles are updated
        mInkObject.Selection = mInkObject.Selection
    End If 
End Sub

private void mInkObject_SelectionResized(object sender, InkOverlaySelectionResizedEventArgs e)
{
    Rectangle newBounds = mInkObject.Selection.GetBoundingBox();
    // Check if we are too small 
    if (newBounds.Height < 500 || newBounds.Width < 500)
    {
        // Resize to back to original rectangle
        mInkObject.Selection.ScaleToRectangle(e.OldSelectionBoundingRect);

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