    Unhappy JButton set background problem

    Hi All,
    When i apply the setBackground() Method to a JButton to set its Background, i face i Problem :
    Under Mac Os : The JButton DOSE NOT change its color,
    when i take my code to my other computer under Windows : OK, the JButton change...
    i am wondering ....
    1) Why under my Mac OS i face this problem...
    2) and Why i get two different results from a same code ??? Java is not Portable?? and independant of the OS?? or it is the swing that makes the problem???
    My code is so simple :
    MyJButton.setBackground(new Color(255,100,100));
    Thanks to any help...

    Default Re: JButton set background problem

    Check to see if your button is being set opaque or not. That will effect if the background color is set or not. And Mac's are funny, they have their own special JDK you download from apple. It should be cross-compatible with the official one released by sun (well, Oracle now), but I'm not completely sure about this.
