我在Canvas有一个 Shape ,如下所示:
<ScrollViewer>
<Border Height="342" Width="470" HorizontalAlignment="Left"
VerticalAlignment="Top" BorderThickness="3" BorderBrush="Black">
<Canvas Background="White">
<Rectangle Width="200" Height="200" Canvas.Left="103"
Canvas.Top="186" Fill="Red" />
</Canvas>
</Border>
</ScrollViewer>
即使 Rectangle 是 Canvas 子项,它也会在 Canvas 限制之外绘制,覆盖 Border 底部边框。如何使矩形仅在画布范围内绘制,确保超出的矩形部分不显示?
谢谢。
