question about "cursor fetching text" function

[wgan]

I'm planning to write a dictionary for fun and like to implement the function so called "cursor fetching text" (I'm not quite sure about the exact word) which appears in most commercial dictionary applications, it's a function you move the cursor to the specific text (anywhere of the screen, as long as it's text/string), then a window contains the translated info will pop-up automatically; how can i fetch the text of the screen using wxwindows, and is the set of functions cross-platform or non-portable, I'm using window xp. thanks.

This sounds like a very difficult task to do cross platform. I'm guessing that tools that do this are not doing window/control inspection. I would think that they might be using OCR. They probably take a screen shot and use OCR in an area around the mouse.
