I'm currently learning how swing works and trying to write a program that allows a user to add stars to a canvas (an exercise set forth in Roberts' Art and Science of Java). Everything works except the slider, which doesn't actually "slide" when I run it from eclipse. It does what it's supposed to do, (resize the stars), but the slider button itself doesn't move when you grab it and slide left or right. Is this a problem with the code or something strange in Eclipse, perhaps? Any help is appreciated.
Thanks. I'm using Eclipse 4.1; do you have any idea what I might try to change? I think everything is default, since I don't really know enough to mess around with the settings (often I change the application size, but that's all).
