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 python3
import os
import sys
from PyQt5.QtCore import (QMimeData, Qt)
from PyQt5.QtWidgets import (QApplication, QDialog, QGridLayout, QLabel,
    QPushButton)
from PyQt5.QtGui import QPixmap
class 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_()
