在基于python/tkinter的文本edi中实现textautocompletion

Question

我想在主文本窗口中使用自动完成算法（不是Tkinter.入口-在下面的代码框中提供了这个简单的Tkinter文本编辑器的示例。我认为being的自动完成算法依赖于一个自动完成的单词列表，即代码示例[1]中提供的。在

到目前为止，我已经找到了两个自动完成的代码示例，一个是使用输入框[1]的Tkinter，另一个是空闲[2]（Jerry King，）的外部模块。在

到目前为止，我所有试图通过将[1]代码的元素移动到文本编辑器来生成工作代码的尝试都失败了。请注意，我对Tkinter相当陌生，因此也在与整个框架进行斗争

好吧，经过一番努力，我终于明白了：

我使用了IDLE中的AutoComplete和AutocompleteWindow模块，并为手动添加了所需的窗口参数。每次敲击键盘上的特定字符集时，都会调用自动完成功能。在
