'用途
Dim instance As InkOverlaySelectionMovedEventArgs
Dim value As Rectangle

value = instance.OldSelectionBoundingRect

屬性值

型別：System.Drawing.Rectangle
選定的 Strokes 集合在 SelectionMoved 事件引發之前的週框。

備註

OldSelectionBoundingRect 屬性會取得選定的 Strokes 集合在 SelectionMoved 事件引發之前的所在位置。

範例

在這個範例中，SelectionMoved 事件處理常式會在選取範圍移動之後檢查它。如果選定的 Strokes 集合已移動，使選取範圍的任何部分離開視窗左方或上方，則選取範圍會移回其原始位置。

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;
    }
