Pyside2将键绑定到方法调用，而不是绑定到按钮或菜单

from PySide2.QtWidgets import QApplication, QMainWindow, QAction, QShortcut
from PySide2.QtGui import QKeySequence

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

        self.initUI()

    def initUI(self):
        # 创建一个动作
        action = QAction("Action", self)
        action.setShortcut(QKeySequence("Ctrl+Q"))

        # 将动作绑定到方法调用
        action.triggered.connect(self.someMethod)

        # 创建一个快捷键
        shortcut = QShortcut(QKeySequence("Ctrl+S"), self)
        shortcut.activated.connect(self.anotherMethod)

        # 创建菜单栏和菜单项
        menubar = self.menuBar()
        file_menu = menubar.addMenu("File")
        file_menu.addAction(action)

        self.setWindowTitle("Pyside2 Key Binding Example")
        self.setGeometry(300, 300, 400, 300)

    def someMethod(self):
        print("Action triggered")

    def anotherMethod(self):
        print("Shortcut activated")

if __name__ == "__main__":
    app = QApplication([])
    window = MainWindow()
    window.show()
    app.exec_()
