如何在PyQt中将终端输出显示到文本框中

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QTextEdit
from PyQt5.QtCore import Qt

class TerminalTextEdit(QTextEdit):
    def write(self, text):
        self.moveCursor(QTextCursor.End)
        self.insertPlainText(text)
        self.moveCursor(QTextCursor.End)

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

        self.initUI()

    def initUI(self):
        self.setWindowTitle("Terminal Output")
        self.setGeometry(100, 100, 800, 600)

        self.textEdit = TerminalTextEdit(self)
        self.setCentralWidget(self.textEdit)

app = QApplication(sys.argv)
window = MainWindow()

sys.stdout = window.textEdit
sys.stderr = window.textEdit

window.show()

sys.exit(app.exec_())
