Some time ago I saw a nice effect in netbeans IDE. When my cursor stops on the Generated Code text (e.g. in generated JFrame), some kind of hint (preview of generated code) is visible (has grey background).
I searched it and I didn’t found anything. My question is what is that component and how does it works? I suspect that is specific TextPane/EditorPane or something like that.
