wx Python小部件是否对整个窗口（全局）中的鼠标单击做出反应？

使用下面的代码段，生成如下内容：

。。。我想让蓝色（子类面板）小部件变成红色，每次用户用鼠标左键单击应用程序框架窗口中的任何位置。就目前的情况而言，它只在小部件本身被点击时才会做出反应——但它不会对点击按钮或框架中的其他地方做出反应

所以我的问题是：

• 在wxPython中，这个小部件是否可以监听“全局”点击
• 如果是-在下面的示例中如何执行

（仅仅更改父项，例如，

self.parent.Bind（wx.EVT\u MOUSE\u EVENTS，self.OnMouseEvents）

根本不起作用；我也找到了，但我根本找不到正确的语法来设置它，使其起作用）

好吧，我想这是我的功劳；但请注意：

• “wxMouseEvent不传播”
• “各种消息来源称（在实际的wxFrame元素中捕获鼠标事件）是不可能的，应该使用WxPanel来捕获事件”；“一些鼠标事件转到帧，如wxEVT_ENTER（或任何名称）。其他鼠标事件转到面板，如wxEVT_RIGHT_UP。您可以将这些事件转发到帧。”；鼠标事件不会在窗口层次结构中向上传播，因此，如果您的帧完全被其他窗口覆盖，那么它首先不会获取任何鼠标事件，因此您无法在那里捕获它们
• 每当您有wxFrame的一个子对象时，wxWidgets会自动假定您希望它覆盖wxFrame的整个区域。因此，框架的任何部分都不可见-因此，没有任何事件会将其发送给您的处理程序

综上所述，解决方案是：

• 递归地遍历框架中的所有（子）小部件
• 将鼠标左下/上事件单独连接到单个事件处理程序
• 确保单个事件处理程序以

  event.Skip（）

  结尾，以便将事件传播到原始按钮等，使其原始单击处理程序也能工作

通过下面的代码，我可以得到：

请注意，屏幕截图上鼠标所在的区域被尺寸测量仪“覆盖”，但尺寸测量仪不处理点击-因此，基本上是框架本身对点击做出响应（将监控方框变成红色）。因此，框架窗口表面的每个小部件基本上都处理自己的区域；任何没有被覆盖的东西——即使在那个区域有施胶器——实际上都是由框架来处理的

我更了解PyQt，但当您绑定并单击面板时，它只适用于面板本身。我不知道这是否可能，把它放在整个窗口上（这样按钮就会被整个窗口层覆盖）谢谢，@ProgrammingIsAwsome-没有意识到这一点，我只是找到了这样的链接，其中正好提到。。。干杯所以我不确定我只是在猜测，因为对我来说，这种叠加不会产生好的结果。我的意思是，那里的按钮会被覆盖，或者一次做多件事
