Thread: opacity bug? or just my code

this is my problem:
1.png

as we can see, the labels and jbuttons looked like they are opaque but i set:

lblTime.setOpaque(false);
b1.setOpaque(false);
b2.setOpaque(false);
b3.setOpaque(false);

i also have this:

public mainClass(){
        setUndecorated(true);
        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
 
        pic.setIcon(new javax.swing.ImageIcon(getClass().getResource("/logo.png")));
        pic.setHorizontalAlignment(SwingConstants.CENTER);
        pic.setBackground(new Color(53,53,53));
        pic.setOpaque(true);
        pic.setSize(230, 180);
 
        this.add(pic);
        this.add(hP);
 
        pack();
 
        setLocation(screenSize.width-getSize().width - 25, 25);
 
    }

hP is the panel, and mainClass is a frame..

please tell me why the labels and buttons still show background :/

Are you sure your code that sets opacity is being called? Add a printline to make sure...

If you have verified the code is being called, post more of the code.
