将登录框中的取消按钮使用信号和槽的机制，关闭界面。

将登录按钮使用信号和槽连接到自定义的槽函数中，在槽函数中判断ui界面上输入的账号是否为"admin"，密码是否为"123456",如果账号密码匹配成功，当前界面关闭，另一个界面展开。如果匹配失败，则输出登录失败，并将密码框和账号框中的内容清空

 pyside转换前

 

Pyside将ui转换为py文件，将项目资源导入后 

 

代码如下：（主执行代码）

import sys
from PySide6.QtCore import Qt
from PySide6.QtWidgets import QWidget,QApplicationfrom login_sea import Ui_Form
from login_succes import Ui_Form2#界面1（按钮）
class MyWidget(Ui_Form,QWidget):def __init__(self):super().__init__()self.setupUi(self)self.pushButton.clicked.connect(btn_def)#界面2
class SecMyWidget(Ui_Form2,QWidget):def __init__(self):super().__init__()self.setupUi(self)def btn_def():name = myWidget.lineEdit_1.text()password = myWidget.lineEdit_2.text()if name=='admin'and password=='123456':myWidget.close()second.show()else:print('输入错误')if __name__ =='__main__':app = QApplication(sys.argv)myWidget=MyWidget()myWidget.setWindowFlag(Qt.WindowType.FramelessWindowHint)myWidget.setAttribute(Qt.WidgetAttribute.WA_TranslucentBackground)myWidget.show()second=SecMyWidget()second.setWindowFlag(Qt.WindowType.FramelessWindowHint)second.setAttribute(Qt.WidgetAttribute.WA_TranslucentBackground)#阻塞sys.exit(app.exec())

 剩下两个页面的ui转py代码：
