not much to say about it, its a simple jbutton, the code is the following
to see the difference i mean you must try this code first and then put "WindowsClassicLookAndFeel"
im trying messing around with the uimanager, but nothing seems to work, unless one would write uimanager.put("ButtonUI",some basic ui) and lose all the button features such as highlightning etc,
wonder what is the key string that identifies that line border in the uimanager to set it false somehow...
