Dim value As Rectangle

value = instance.NewPixelRect

public Rectangle NewPixelRect { get; }

在 SelectionMoving 事件后所选内容将移动到的矩形区域。

示例

在下面的示例中，SelectionMoving 事件处理程序在所选内容移动之前检查该内容。如果所选内容的任何部分移动到窗口边界之外，则事件处理程序将通过更改每个所选 Stroke 对象的 Color 属性，将所选内容的颜色更改为红色。

Private Sub mInkObject_SelectionMoving(ByVal sender As Object, ByVal e As InkOverlaySelectionMovingEventArgs)
    If e.NewPixelRect.Left < 0 Or e.NewPixelRect.Top < 0 Or _
       e.NewPixelRect.Right > mInkObject.AttachedControl.ClientRectangle.Width Or _
       e.NewPixelRect.Bottom > mInkObject.AttachedControl.ClientRectangle.Height Then

        For Each stroke As Stroke In mInkObject.Selection
            ' change the stroke color
            stroke.DrawingAttributes.Color = Color.Red
        Next

    End If
End Sub

private void mInkObject_SelectionMoving(object sender, InkOverlaySelectionMovingEventArgs e)
{
    if (e.NewPixelRect.Left < 0 || e.NewPixelRect.Top < 0 ||
        e.NewPixelRect.Right > mInkObject.AttachedControl.ClientRectangle.Width ||
        e.NewPixelRect.Bottom > mInkObject.AttachedControl.ClientRectangle.Height)
    {
        foreach (Stroke stroke in mInkObject.Selection)
        {
            // change the stroke color
            stroke.DrawingAttributes.Color = Color.Red;
        }
    }
}
