        self.setWindowTitle('学习剪贴板')

    def copyText(self):

        clipboard.setText('hello world')
    def pasteText(self):

        QClipboard.setPixmap(QPixmap('./images/abc.jpg'))
    def pasteImage(self):
        QClipboard = QApplication.clipboard()
        self.imageLabel.setPixmap(QClipboard.pixmap())

    def copyHtml(self):
        mimeData = QMimeData()
        mimeData.setHtml('<b>Bold and <font color=red>Red</font></b>')
        QClipboard = QApplication.clipboard()
        QClipboard.setMimeData(mimeData)

    def pasteHtml(self):
        QClipboard = QApplication.clipboard()
        mimeData  = QClipboard.mimeData()
        if QMimeData.hasHtml():
            self.textLabel.setText(mimeData.html())
if __name__ == '__main__':
    app = QApplication(sys.argv)
    main = ClipBoard()
    main.show()
    sys.exit(app.exec_())

代码运行效果图如下：
