【问题描述】：
我有一个问题，为什么我的文本windget 没有正确打包到这段代码中。作为记录，它应该读取用户文档文件夹中的日志文件，并在文本小部件中显示内容，将红色警告和错误以及蓝色信息着色。任何帮助将不胜感激！
这是我想出的新代码，但 Text 小部件没有打包在主框架内...

【问题讨论】：
-
你能给我们错误信息吗？还是没有？
-
您能更具体地说明没有正确包装是什么意思吗？
-
也许我错了，但 self.output.pack() 不应该出现在 self.output.config() 之后吗？
-
@Cribber：
pack和config的顺序无关紧要。 -
您还有一个问题，即您正在创建一个内部框架 (
self.frame) 作为根的子级而不是GUI的子级。虽然这会起作用，但这不是你应该这样做的方式。使GUI继承自tk.Frame的全部意义在于，该类创建的所有内容都在该框架内。
