PyQT5 动态添加的按钮和标签事件绑定问题
如下代码所示，动态添加的label绑定点击和鼠标悬停事件都不执行，请问各位大佬该怎么写动态添加的button添加点击事件怎么把自己的属性作为参数传进去，或者其他内容参数。
tkinter 做了一个版本可以这么写
self.content_btn = Button(
self.frame1, text=value, width=40, command=lambda arg=value: self.text_click(arg))
但是qt实在不会，求大佬指导一下{:5_92:}

tital_labels.linkHovered.connect(self.linkHovered) # 不执行

你没给完整代码 我就参考https://blog.csdn.net/iblctw/article/details/106421326的demo，改了一下 看是不是你需要的效果 # -*- coding: utf-8 -*-
