推荐答案

如果没有真诚的努力，你所要求的几乎是不可能的。

请记住，由于您的程序与首先呈现单词的目标应用程序（您的浏览器，记事本等）完全没有关联，因此您必须采用不同的策略而不仅仅是简单的鼠标悬停事件。

我的建议是尝试捕获鼠标下的区域然后应用OCR。

我无法想到可以做任何其他方式。

What you are asking for is close to impossible without sincere effort.
Remember that since your program will have absolutely no connection with the target application which has rendered the word in the first place (your browser, notepad etc), you have to resort to different tactics than just a simple mouse hover event.
My suggestion is to try to capture the area under the mouse and then applying OCR.
I can''t think of any other way this can be done.
