PySide 打开一个新的 window，但立即关闭
PySide open a new window, but close immediately
我有一个问题。虽然有些问题和我的很相似，但我找不到如何解决。
我创建了一个登录window，当点击'Confirm'按钮时，希望加载一个新的window。但现在新的 window 将显示并关闭 immediately.The 代码如下：

添加login.py和moreFrame_Modify.py，这两个文件是QT designer生成的
在你的情况下，你有 2 个错误：
你不应该在 GUI 中使用 time.sleep()，在 Qt 的情况下你应该使用 QTimer 因为 time.sleep() 冻结了 GUI。
在函数中创建的局部变量仅在函数执行时存在，在您的情况下 showMemoUI 显示并立即消除，因此新的 window 是没有观察到。解决方案是使 class.
利用上述，解决方案代码为：
import sys
from PySide import QtCore, QtGui

class show_login(QtGui.QWidget, login.Ui_Form):
def __init__(self,parent=None):
super(show_login,self).__init__(parent)
