此代码允许您选择矩形和方形区域。 但我不希望这些区域发生干扰。 这意味着你无法重新选择该区域。 请求帮助我。

This code allows you to select a rectangular and square areas. But I do not want these areas to interfere. It means you can not re-select the region. pleas help me.

我尝试过： 此代码允许您选择矩形和方形区域。 但我不希望这些区域发生干扰。 这意味着您无法重新选择该区域。

What I have tried: This code allows you to select a rectangular and square areas. But I do not want these areas to interfere. It means you can not re-select the region.

推荐答案

使用地区类 [ ^ ]它是Intersect方法 - 如果结果区域非空，他们干涉 Use the Region class[^] and it's Intersect method - if the resulting region is non-empty, they "interfere"
