The images are pretty basic geometric patterns + drop shadow, so my gut feeling is that it should be pretty straightforward to replace the files with an icon factory that can generate images given a base colour. ...
I've found several pages and SO answers about the enter-as-tab problem in Java, but all propose either overriding methods of JTextField or adding a key listener to every component. But isn't there any other way? Can't I override something of the LookAndFeel or install some global policy? ...
