PyQt 和 MVC 模式

使用PyQt和MVC模式创建Python图形界面应用程序

python
from PyQt5.QtWidgets import QApplication, QMainWindow, QLabel, QLineEdit, QPushButton
class LoginModel:
    def __init__(self):
        self.username = ""
        self.password = ""
class LoginView(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("登录")
        self.setGeometry(100, 100, 300, 200)
        self.username_label = QLabel("用户名:", self)
        self.username_label.move(50, 50)
        self.username_input = QLineEdit(self)
        self.username_input.move(120, 50)
        self.password_label = QLabel("密码:", self)
        self.password_label.move(50, 90)
        self.password_input = QLineEdit(self)
        self.password_input.move(120, 90)
        self.password_input.setEchoMode(QLineEdit.Password)
        self.login_button = QPushButton("登录", self)
        self.login_button.move(120, 130)
class LoginController:
    def __init__(self, model, view):
        self.model = model
        self.view = view
        self.view.login_button.clicked.connect(self.login)
    def login(self):
        self.model.username = self.view.username_input.text()
        self.model.password = self.view.password_input.text()
        print("用户名:", self.model.username)
        print("密码:", self.model.password)
if __name__ == "__main__":
    app = QApplication([])
    model = LoginModel()
    view = LoginView()
    controller = LoginController(model, view)
    view.show()
    app.exec_()
