PyQt:在两个不同的qlistwidgets中同步滚动？

from PyQt5.QtWidgets import QApplication, QListWidget, QScrollBar, QVBoxLayout, QWidget
from PyQt5.QtCore import Qt

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

        # 创建两个QListWidget对象
        self.listWidget1 = QListWidget()
        self.listWidget2 = QListWidget()

        # 垂直布局
        layout = QVBoxLayout()
        layout.addWidget(self.listWidget1)
        layout.addWidget(self.listWidget2)

        self.setLayout(layout)

        # 获取两个QListWidget的滚动条
        scrollbar1 = self.listWidget1.verticalScrollBar()
        scrollbar2 = self.listWidget2.verticalScrollBar()

        # 连接滚动条的valueChanged信号
        scrollbar1.valueChanged.connect(self.syncScroll)
        scrollbar2.valueChanged.connect(self.syncScroll)

        # 添加一些示例数据
        for i in range(100):
            self.listWidget1.addItem(f"Item {i}")
            self.listWidget2.addItem(f"Item {i}")

    def syncScroll(self, value):
        # 将一个QListWidget的滚动位置设置为另一个QListWidget的滚动位置
        self.listWidget1.verticalScrollBar().setValue(value)
        self.listWidget2.verticalScrollBar().setValue(value)

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