如何让2个矩形选择器同时在同一区域移动
how make 2 rectangle selector move in the same times and in the same area
我需要定义 2 个在同一时间和同一区域移动的矩形选择器，当我移动彼此时，我该怎么做？
这是一个简单的代码，在 2 个面板和 2 个矩形中有 2 个绘图
可以让两个矩形同时移动，因为我没有在网络或 matplotlib 中找到任何例子
我使用 wxpython 4 python3.6

我不知道这是否是应该的方式，但这是一种方式。
我在适当的地方评论了代码。
该方法只是简单地抓取第一个 Rectangle 的坐标，将它们强制放入第二个 Rectangle 中，然后重新绘制它。
第二个矩形被设置为非活动状态，因为它是第一个 and 的从属对象，如果它不是非活动状态，角落和中间的控制点将无法与矩形一起移动。这使我相信可能有一种不那么棘手的方法可以达到相同的结果。
