连接2个小部件，PyQt

Question

我有一个问题连接2个窗口在一起没有破坏主循环。你能帮我连接这两个PyQt文件吗？第二个文件应该按下按钮打开。

假设你的文件被命名为a.py和b.py，进口b在为创建一个新的对象调用show它

我不得不注释掉一些代码，使其运行，所以一定要确保你＃2粘贴代码，发布您的问题之前运行

我不会建议你继续这样你应该学会从Qt设计

修改自动生成的UI文件来组织你的项目相应的，而不是来看看这个链接，可以帮助你组织你的PyQt的项目Saving connect statements pyqt when UI is still changing和

我的GitHub库，它是PySide但概念是stil l相同
