非常抱歉，这是我的疏忽导致的错误。在PySide6中，使用`exec()`方法来显示窗口会导致该错误。正确的方法是使用`show()`方法来显示窗口。以下是修正后的代码：import sysfrom PySide6.QtCore import Signalfrom PySide6.QtWidgets import QApplication, QMainWindow, QVBoxLayout, QLabel, QLineEdit, QPushButton, QWidgetclass MainWindow(QMainWindow): def __init__(self): super().__init__() self.setWindowTitle("Main Window") self.setGeometry(100, 100, 400, 300) layout = QVBoxLayout() label = QLabel("Welcome to the App!", self) layout.addWidget(label) button = QPushButton("Login", self) button.clicked.connect(self.show_login_window) layout.addWidget(button) central_widget = QWidget(self) central_widget.setLayout(layout) self.setCentralWidget(central_widget) def show_login_window(self): login_window = LoginWindow() login_window.login_success.connect(self.show_user_info) login_window.show() def show_user_info(self, username, password): info_window = UserInfoWindow(username, password) info_window.exec_()class LoginWindow(QMainWindow): login_success = Signal(str, str) def __init__(self): super().__init__() self.setWindowTitle("Login") self.setGeometry(100, 100, 400, 300) layout = QVBoxLayout() label_username = QLabel("Username:", self) layout.addWidget(label_username) self.input_username = QLineEdit(self) layout.addWidget(self.input_username) label_password = QLabel("Password:", self) layout.addWidget(label_password) self.input_password = QLineEdit(self) self.input_password.setEchoMode(QLineEdit.Password) layout.addWidget(self.input_password) button_login = QPushButton("Login", self) button_login.clicked.connect(self.login) layout.addWidget(button_login) central_widget = QWidget(self) central_widget.setLayout(layout) self.setCentralWidget(central_widget) def login(self): username = self.input_username.text() password = self.input_password.text() self.login_success.emit(username, password) self.close()class UserInfoWindow(QMainWindow): def __init__(self, username, password): super().__init__() self.setWindowTitle("User Info") self.setGeometry(100, 100, 400, 300) layout = QVBoxLayout() label = QLabel(f"Welcome, {username}!

点击button_login后一闪而过，看不清楚是什么。

请问能不能用PySide6实现：
1、建立BassWindow（1440*900，淡蓝色背景）。定义Esc事件和退出按钮。

有欢迎界面和用户登录界面（用户名和密码录入框）。

如果用户所录入的用户名和密码正确，屏幕正中央竖排居中显示5个按钮(这5个按钮

将来要对应5个不同功能的子模块)。

当然可以！以下是使用PySide6实现你描述的功能：

from PySide6.QtWidgets import QApplication, QMainWindow, QVBoxLayout, QLabel, QLineEdit, QPushButton, QWidget

class BaseWindow(QMainWindow):
def __init__(self):

   self.setWindowTitle("Base Window")
   self.setGeometry(100, 100, 1440, 900)

   self.setPalette(palette)

def keyPressEvent(self, event):

   label.setFont(QFont("Arial", 24, QFont.Bold))
   layout.addWidget(label)

   button_login = QPushButton("Login", self)

   central_widget.setLayout(layout)

class LoginWindow(BaseWindow):

def __init__(self):
   super().__init__()

   layout = QVBoxLayout()

   label_username = QLabel("Username:", self)
   layout.addWidget(label_username)
   self.input_username = QLineEdit(self)
   layout.addWidget(self.input_username)

   label_password = QLabel("Password:", self)
   layout.addWidget(label_password)
   self.input_password = QLineEdit(self)
   self.input_password.setEchoMode(QLineEdit.Password)
   layout.addWidget(self.input_password)

   button_login = QPushButton("Login", self)
   button_login.clicked.connect(self.login)
   layout.addWidget(button_login)

   central_widget = QWidget(self)
   central_widget.setLayout(layout)
   self.setCentralWidget(central_widget)

def login(self):
   username = self.input_username.text()
   password = self.input_password.text()
   # 进行用户名和密码的验证逻辑，这里只做简单演示
   if username == "admin" and password == "password":
         self.login_success.emit()

class MainWindow(BaseWindow):
def __init__(self):
   super().__init__()

   layout = QVBoxLayout()

   button1 = QPushButton("Button 1", self)
   layout.addWidget(button1)

   button2 = QPushButton("Button 2", self)
   layout.addWidget(button2)

   button3 = QPushButton("Button 3", self)
   layout.addWidget(button3)

   button4 = QPushButton("Button 4", self)
   layout.addWidget(button4)

   button5 = QPushButton("Button 5", self)
   layout.addWidget(button5)

   central_widget = QWidget(self)
   central_widget.setLayout(layout)
   self.setCentralWidget(central_widget)

if __name__ == "__main__":
app = QApplication(sys.argv)

welcome_window = WelcomeWindow()
login_window = LoginWindow()
main_window = MainWindow()

# 窗口切换逻辑
welcome_window.switch_to_login.connect(login_window.show)
login_window.login_success.connect(main_window.show)

welcome_window.show()

sys.exit(app.exec())

运行这个程序，会先显示欢迎界面，点击登录按钮后切换到登录界面。在登录界面中，输入正确的用户名和密码（默认是`admin`和`password`），点击登录按钮后切换到主窗口，其中屏幕正中央竖排居中显示了5个按钮。你可以根据需要，为每个按钮添加具体的功能代码。如果要实现不同功能的子模块，可以使用`QStackedWidget`来管理窗口的切换。希望这个示例能帮助到你！

BaseWindow还差1个退出按钮，要求此退出按钮和ESc事件都能被后续的窗体继承。

非常抱歉，以下是对代码进行修改的版本，添加了退出按钮并使其能够被后续窗体继承：import sysfrom PySide6.QtCore import Qt, Signalfrom PySide6.QtGui import QPalette, QColor, QFont, QMessageBoxfrom PySide6.QtWidgets import QApplication, QMainWindow, QVBoxLayout, QLabel, QLineEdit, QPushButton, QWidgetclass BaseWindow(QMainWindow): def __init__(self): super().__init__() self.setWindowTitle("Base Window") self.setGeometry(100, 100, 1440, 900) palette = self.palette() palette.setColor(QPalette.Window, QColor("#87CEFA"))# 淡蓝色背景 self.setPalette(palette) self.setup_exit_button() def setup_exit_button(self): button_exit = QPushButton("Exit", self) button_exit.clicked.connect(self.close) button_exit.setStyleSheet("QPushButton {color: red;}") button_exit.move(self.width() - 100, 10) button_exit.setParent(self) def keyPressEvent(self, event): if event.key() == Qt.Key_Escape:# 捕捉Esc键事件 reply = QMessageBox.question(self, "确认", "确定要退出系统吗？", QMessageBox.Yes | QMessageBox.No, QMessageBox.No) if reply == QMessageBox.Yes: self.close()class WelcomeWindow(BaseWindow): switch_to_login = Signal()# 切换到登录界面信号 def __init__(self): super().__init__() layout = QVBoxLayout() label = QLabel("Welcome to the App!", self) label.setFont(QFont("Arial", 24, QFont.Bold)) layout.addWidget(label) button_login = QPushButton("Login", self) button_login.clicked.connect(self.switch_to_login.emit) layout.addWidget(button_login) central_widget = QWidget(self) central_widget.setLayout(layout) self.setCentralWidget(central_widget)class LoginWindow(BaseWindow): login_success = Signal()# 登录成功信号 def __init__(self): super().__init__() layout = QVBoxLayout() label_username = QLabel("Username:", self) layout.addWidget(label_username) self.input_username = QLineEdit(self) layout.addWidget(self.input_username) label_password = QLabel("Password:", self) layout.addWidget(label_password) self.input_password = QLineEdit(self) self.input_password.setEchoMode(QLineEdit.Password) layout.addWidget(self.input_password) button_login = QPushButton("Login", self) button_login.clicked.connect(self.login) layout.addWidget(button_login) central_widget = QWidget(self) central_widget.setLayout(layout) self.setCentralWidget(central_widget) def login(self): username = self.input_username.text() password = self.input_password.text() # 进行用户名和密码的验证逻辑，这里只做简单演示 if username == "admin" and password == "password": self.login_success.emit() else: QMessageBox.warning(self, "登录失败", "用户名或密码错误，请重新输入。") self.input_username.clear() self.input_password.clear()class MainWindow(BaseWindow): def __init__(self): super().__init__() layout = QVBoxLayout() button1 = QPushButton("Button 1", self) layout.addWidget(button1) button2 = QPushButton("Button 2", self) layout.addWidget(button2) button3 = QPushButton("Button 3", self) layout.addWidget(button3) button4 = QPushButton("Button 4", self) layout.addWidget(button4) button5 = QPushButton("Button 5", self) layout.addWidget(button5) central_widget = QWidget(self) central_widget.setLayout(layout) self.setCentralWidget(central_widget)if __name__ == "__main__": app = QApplication(sys.argv) welcome_window = WelcomeWindow() login_window = LoginWindow() main_window = MainWindow() login_window.login_success.connect(main_window.show) welcome_window.switch_to_login.connect(login_window.show) login_window.show() sys.exit(app.exec())现在，BaseWindow中已经添加了一个名为“Exit”的退出按钮，并且在继承该类的其他窗体中也可以看到这个退出按钮。同时，按下Esc键时也会弹出确认对话框。希望这次的修改满足你的需求！
