下面是一个简单登录界面的搭建

python 复制代码 
import sys

# 从PySide6中导入必要的模块，用于创建GUI界面
from PySide6.QtWidgets import QApplication, QWidget, QPushButton, QLineEdit
from QtCore import Qt

# 导入Qt Designer生成的UI文件
from TAJ import Ui_Form
from second import Ui_Form2


# 主窗口类，表示第一个登录页面
class MyWidget(Ui_Form, QWidget):
    def __init__(self):
        # 初始化QWidget并设置UI界面
        super().__init__()
        self.setupUi(self)

        # 通过对象名称查找子控件（按钮和文本框）
        self.btn1 = self.findChild(QPushButton, "log_on")  # 登录按钮
        self.btn2 = self.findChild(QPushButton, "cancel")  # 取消按钮
        self.userid = self.findChild(QLineEdit, "userid")  # 用户名输入框
        self.pwd = self.findChild(QLineEdit, "password")  # 密码输入框

        # 连接按钮点击事件到相应的函数
        self.btn1.clicked.connect(self.logon)  # 连接登录按钮点击事件到logon函数
        self.btn2.clicked.connect(self.exit)  # 连接取消按钮点击事件到exit函数

    def logon(self):
        # 处理登录操作的函数
        if self.userid.text() == "admin" and self.pwd.text() == "123456":  # 验证用户名和密码是否正确
            print("登录成功")  # 打印"登录成功"
            self.close()  # 关闭当前窗口
            self.second = Second()  # 创建第二个窗口的实例
            self.second.show()  # 显示第二个窗口
        else:
            print("登录失败")  # 打印"登录失败"
            self.userid.setText("")  # 清空用户名输入框
            self.pwd.setText("")  # 清空密码输入框

    def exit(self):
        # 处理取消按钮点击事件的函数
        print("取消登录")  # 打印"取消登录"
        self.close()  # 关闭当前窗口


# 第二个页面类（登录成功后显示）
class Second(Ui_Form2, QWidget):
    def __init__(self):
        # 初始化QWidget并设置UI界面
        super().__init__()
        self.setupUi(self)


# 程序主入口
if __name__ == "__main__":
    app = QApplication(sys.argv)  # 创建QApplication对象，程序必须有一个QApplication对象
    my_widget = MyWidget()  # 创建MyWidget类的实例
    my_widget.setWindowFlag(Qt.WindowType.FramelessWindowHint)  # 设置窗口为无边框
    my_widget.setAttribute(Qt.WidgetAttribute.WA_TranslucentBackground)  # 设置窗口背景为透明
    my_widget.show()  # 显示主窗口
    sys.exit(app.exec())  # 启动事件循环，直到程序关闭

调用的主页面搭建如下
