Most likely you won’t be able to draw directly to the screen, but you could potentially grab screenshots of each screen and then draw onto those. Depending on what exactly you’re trying to do with your application, it would almost definitely be a more realistic goal to grab a screenshot of each screen and then simply display the screenshots in standard windows that take up the entire screen, letting you then edit and “draw” onto the screen there.
Another option would be to create a transparent window, and then intercept mouse clicks and present information on that window.
If you’re using RB on a Mac, you can use the Monkeybread Software Plugin to create a NSWindowMBS and modify the alpha value or an OverlayWindowMBS. It looks like you’re trying to do this on Windows, though, so this won’t work.
