python - 使用类时将用户输入保存到文本小部件 Tkinter

Question

我想知道如何在按下“提交”按钮时保存用户在 Text 小部件中输入的文本。目前，我有函数submitbutton，但在单击“提交”时出现错误。

另一方面，我希望右上角的 Label 小部件在文件打开并显示在左侧时更改其文本。

到目前为止我的代码是:

您需要保存对文本小部件的引用，并将参数传递给 get 方法，以告诉它要获取的数据范围:

self.bottom = ScrolledText(m2, wrap=WORD)
...
print self.bottom.get("1.0", "end-1c")
