本文是对《Python Qt GUI快速编程》的第10章的例子剪贴板用Python3+PyQt5进行改写，分别对文本，图片和html文本的复制与粘帖，三种做法大同小异。

#!/usr/bin/env python3import osimport sysfrom PyQt5.QtCore import (QMimeData, Qt)from PyQt5.QtWidgets import (QApplication, QDialog, QGridLayout, QLabel, QPushButton)from PyQt5.QtGui import QPixmapclass Form(QDialog): def __init__(self, parent=None): super(Form, self).__init__(parent) textCopyButton = QPushButton("&Copy Text") textPasteButton = QPushButton("Paste &Text") htmlCopyButton = QPushButton("C&opy HTML") htmlPasteButton = QPushButton("Paste &HTML") imageCopyButton = QPushButton("Co&py Image") imagePasteButton = QPushButton("Paste &Image") self.textLabel = QLabel("Original text") self.imageLabel = QLabel() self.imageLabel.setPixmap(QPixmap(os.path.join( os.path.dirname(__file__), "images/clock.png"))) layout = QGridLayout() layout.addWidget(textCopyButton, 0, 0) layout.addWidget(imageCopyButton, 0, 1) layout.addWidget(htmlCopyButton, 0, 2) layout.addWidget(textPasteButton, 1, 0) layout.addWidget(imagePasteButton, 1, 1) layout.addWidget(htmlPasteButton, 1, 2) layout.addWidget(self.textLabel, 2, 0, 1, 2) layout.addWidget(self.imageLabel, 2, 2) self.setLayout(layout) textCopyButton.clicked.connect(self.copyText) textPasteButton.clicked.connect(self.pasteText) htmlCopyButton.clicked.connect(self.copyHtml) htmlPasteButton.clicked.connect(self.pasteHtml) imageCopyButton.clicked.connect(self.copyImage) imagePasteButton.clicked.connect(self.pasteImage) self.setWindowTitle("Clipboard") def copyText(self): clipboard = QApplication.clipboard() clipboard.setText("I've been clipped!") def pasteText(self): clipboard = QApplication.clipboard() self.textLabel.setText(clipboard.text()) def copyImage(self): clipboard = QApplication.clipboard() clipboard.setPixmap(QPixmap(os.path.join( os.path.dirname(__file__), "images/gvim.png"))) def pasteImage(self): clipboard = QApplication.clipboard() self.imageLabel.setPixmap(clipboard.pixmap()) def copyHtml(self): mimeData = QMimeData() mimeData.setHtml("<b>Bold and <font color=red>Red</font></b>") clipboard = QApplication.clipboard() clipboard.setMimeData(mimeData) def pasteHtml(self): clipboard = QApplication.clipboard() mimeData = clipboard.mimeData() if mimeData.hasHtml(): self.textLabel.setText(mimeData.html())if __name__ == "__main__": app = QApplication(sys.argv) form = Form() form.show() app.exec_()
