如何在pyqt qdock小部件中添加图像

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QDockWidget, QLabel
from PyQt5.QtGui import QPixmap

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

    def initUI(self):
        dock = QDockWidget("Image Dock", self)
        self.addDockWidget(1, dock)

        label = QLabel(dock)
        pixmap = QPixmap("image.jpg")  # 替换为你的图像文件路径
        label.setPixmap(pixmap)
        dock.setWidget(label)

        self.setWindowTitle("Image Dock Example")
        self.setGeometry(100, 100, 800, 600)
        self.show()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    mainWindow = MainWindow()
    sys.exit(app.exec_())
