Acces Computer through Engine


I’ve been looking for programs and other resources for help on making an engine access the computer while being running.

(In the game, 3rd person type game, access to the computer screen that the game is running on, like it was a website browser widget.)

I am unable to find such info or code. The closes thing I got was a website browser widget, though its not what I am looking for.

Does anyone know how to do this?
