Question

当我想使用tkinter填充输入框时，我遇到了问题。我当前的脚本正在调用另一个脚本来获取值。然后我希望数据显示在Tkinter输入框中。

这是我当前的代码，我已经尝试了tbName.set("tbName", account.getName())这样的事情（有和没有tbName）我也试过了StringVar。我不确定我是否使用它错了。我查看了以下网站：effbot。我是Python的新手，所以任何帮助都会受到谴责。

如果要在“条目”窗口小部件中设置文本，则需要使用Entry.insert(0,'text')而不是v.set。 insert方法中的0是您要插入文本的位置，在这种情况下，它位于Entry的开头。

如果您不希望用户编辑条目中的内容，您可以使用Entry.config(state='readonly');如果您想稍后修改内容，则需要先致电Entry.config(state=NORMAL)，然后才能再次使用Entry.insert。您不需要将StringVar设置为Entry，只需使用Entry.get()即可。

使用tkinter填充Entry
