在 PyQT 中向 QPlainTextEdit 添加文本(结果是状态日志) [英] Add text to QPlainTextEdit in PyQT (the result is a status log)

问题描述

我正在尝试构建一个 StatusLog，应用程序上发生的每一个动作.例如，用户单击了 button1，progressBox 必须接收类似用户单击了 button1"的字符串.

Iam trying to build a StatusLog, every move that happens on application. For example, the user clicked in the button1, the progressBox must receive a string like "user clicked the button1".

我已经搜索并找到了一个链接，但我无法解决这个问题，我不知道如何解决.

I've searched and found a link but I can't put that working out, I dont know how.

链接:将多行添加到 QTextEdit PyQt

每次尝试都会给我，AttributeError: 'QPlainTextEdit' object has no attribute 'insertText'

Is given me everytime I try, AttributeError: 'QPlainTextEdit' object has no attribute 'insertText'

谢谢大家.最好的问候.

Thanks for all. Best Regards.

推荐答案

尝试 insertPlainText() 代替.文档没有提到insertText 所以错误是非常具有描述性.

Try insertPlainText() instead. The documentation does not mention insertText so the error is quite descriptive.
