I have an as-of-now unreleased open source project. I wanted to make the lines thinner with certain LookAndFeel methods like drawGroupComponentOutline(), for example. The only change I wanted to make was to the hard-coded 2.0f for stroke thickness. So I just copied and pasted the library method into my inheriting class’s overriding method, and tweaked that value. Is it going to be a copyright/licensing problem if I include this in my repo? I suppose the GUI’s not that important for my project but I like the way I’ve got it looking now.
