有什么办法可以让上面的标签直接格式化转换HTML 格式吗？就是不用另一个窗口展示上一个窗口的内容，
我希望一边输入一遍转换在当前的QTextEdit 标签上， 谢谢。。
源代码下方附上： 注释清晰。希望大佬帮忙解决。谢谢

super().__init__(pa)
self.pa = pa
def run(self):
md = self.pa.te.toPlainText() # 获取标签上用户输入的内容。
# print(md)
newhtml = self.pa.md2html(md) # 并传给 md2html 函数进行渲染成HTML格式
self.pa.teeeee.setHtml(newhtml) # 将渲染好的HTML格式富文本显示出来

def __init__(self):
super(Pywindow, self).__init__()
self.resize(400, 500) # 主窗口尺寸
self.te = QTextEdit(self) # 标签1
self.te.move(50, 0)
self.te.resize(300, 200)
self.teeeee = QTextEdit(self)# 标签2
self.teeeee.resize(300, 200)
self.teeeee.move(50, 220)
self.thread1 = thread(self) # 重写的多线程对象
self.te.textChanged.connect(self.thread1.run) # 当内容发生变化时触发此信号，
def md2html(self, mdstr): # mdstr 此函数收到的是用户输入的内容 将其转换成HTML 格式
