PyQt5 技术篇-在clipboard.dataChanged.connect()里如何写入剪切板示例演示，pyqt5监听剪切板变动并写入剪切板内容

import pyperclip

# 写入剪切板
def setCopy(s):
    pyperclip.copy(s)

from PyQt5.QtWidgets import *

app = QApplication([])
clipboard = app.clipboard()

# 当剪切板变动会执行该方法
def change_deal():
    data = clipboard.mimeData()
    
    # 获取剪切板内容
    text = data.text()
    # 当剪切板内容为"改变"时，我就写入剪切板
    if(text == "改变"):
        setCopy("不改变")
    else:
        print(text)

# 监听剪切板变动
clipboard.dataChanged.connect(change_deal)
app.exec_()
