在基于python / tkinter的文本编辑器中实现text-autocompletion

标签: python text autocomplete editor tkinter

我想在下面的代码框中提供的这个简单的Tkinter文本编辑器的主文本窗口中使用自动完成算法(不是Tkinter.entry - 可以找到它的示例)。我认为蜜蜂的自动完成算法依赖于自动填充单词列表,即代码示例[1]中提供的。

到目前为止,我已经找到了两个自动完成的代码示例,一个用于Tkinter,使用了一个输入框[1],另一个用于IDLE [2]的外部模块(由Jerry King提供)。

到目前为止,我通过将[1]代码的元素移动到文本编辑器中来生成工作代码的所有尝试都失败了。请注意,我对Tkinter来说很陌生,因此也在整个框架中挣扎

好吧,经过一番尝试,我发现了它:

我使用了IDLE的AutoComplete和AutocompleteWindow模块,并为手动添加了所需的窗口参数。每次在键盘上点击一组特定字符时,都会调用AutoComplete。
