python - 在PyQT中将文本添加到QPlainTextEdit(结果是状态日志)

我试图建立一个StatusLog，在应用程序上发生的每一步。
例如，用户单击了button1，则progressBox必须接收类似“用户单击button1”的字符串。

我已经搜索并找到了一个链接，但是我无法解决这个问题，我不知道该怎么做。

链接:Add more than one line to a QTextEdit PyQt

每次尝试都给我，AttributeError:'QPlainTextEdit'对象没有属性'insertText'

谢谢大家
最好的祝福。

最佳答案

请尝试insertPlainText()。 The documentation没有提及insertText，因此该错误具有很大的描述性。
