I have a bit of code that creates movable squares on a JPanel for the user to move as they like. I would like to add an option to allow for a re-sizable and movable rectangle to be added to the JPanel along with the squares. I found a bit of code at http://zetcode.com/tutorials/javaswingtutorial/resizablecomponent/ that allows you to create a re-sizable component. My question is, how would I add this to my JPanel. My code is below.
