Python Z排序控件，控件顶部和底部的碰撞检测

我正在pygame中创建控件（按钮和标签是唯一完成的，并且为控件设置工具提示）。我以正确的Z顺序绘制控件，但我试图检测鼠标是否在另一个控件上，因此它只激活可见的控件

这在一定程度上是有效的，如果您删除了测试。在底部设置按钮（btnButton7），即使鼠标位于按钮下方的一个按钮上，它也只会触发按钮7，但如果您单击按钮7下方的一个按钮并将鼠标移到按钮7上，它仍然认为原始按钮正在被单击（不应该）

这几天来我一直在思考这个问题，但我就是看不懂怎么解决它

（另外，我今天早上刚刚考虑过，但我应该将每个控件都转换为一个类而不是一个id，所以稍后会对其进行修改）

代码太长，无法发布，下面是

设置状态和触发消息的所有处理都在process_events方法中完成

（明天24小时超时结束时将选择正确答案）

最后我终于弄明白了，我把事情复杂化了

反向浏览控件列表，.collidepoint成功打开的第一个控件，保存该控件并中断循环

检查所有控件，其中一个未禁用且当前不正常，设置为正常

使用已根据需要保存的控件
