I'm trying to work on a little project, but need to do a couple of things that I don't know how to do. If anybody could set me on the right path I would appreciate it. I need to display an image on the screen first off. Then I need to have the user click on a couple of points and have some sort of symbol that makes it clear where they clicked. Lastly the user needs to be able to click and drag a visible rectangle over an area of the image.
Sorry if this is a stupid question, but it would be great if you could give me a hand. I've just never done anything with a gui before. Oh and by the way, I'll be using codex to compile.
