我正在尝试在点击按钮时从另一个pyqt窗口打开一个pyqt窗口，但我无法抓住它。 python文件opens.py和signup.py都可以独立运行，但我无法想办法链接它们......（点击注册按钮后从opens.py运行signup.py）

opens.py中的注释部分是创建问题的部分。帮助将不胜感激。
答案 0 :(得分：0)
你的Ui_Dialog1应该继承QDialog，它使它成为一个UI对象，但是你继承自object，它没有＆＃34; show＆＃34;方法
def handleTest1(self):
#self.accept()
#self.h=Ui_Dialog1() # You need to move this to __init__ function
#self.h.setupUi(QtGui.QDialog()) # You need to move this to __init__ function
self.h.show() # call the show method here
您需要将self.h = Ui_Dialog1（）和setupUi移动到 init 函数，这样可以避免可能的内存泄漏。 （否则每次点击＆＃34; sigunup＆＃34;，它都会创建一个新对象）
