Background in a JPanel

[petold]

Im stuck with this problem that should be an easy one to solve, even for me but I cant figure it out. Need someone to take a look at the code and maybe slap my face because I cant make this out....lol.

I whant the background in ths JLabel to be white and not the default grey. Ive tried the method setBackground() but that doesn´t made the trick. Please help this out for me.

The code:
----------------------------------------------------------
//Class that creates an AboutLabel.
public class AboutLabel extends JFrame {

private JLabel label;

public AboutLabel ()
{
super( "J.E.R.C" );

Container c = getContentPane();
c.setLayout (new FlowLayout () );

label = new JLabel();
label.setText( "J.E.R.C version 1.0" );
Icon JERC = new ImageIcon("JERC.gif"
setIconImage(new ImageIcon("ikon.gif&quot.getImage());
label.setIcon(JERC);
label.setHorizontalTextPosition (SwingConstants.CENTER);
label.setVerticalTextPosition (SwingConstants.BOTTOM);
label.setOpaque(true);
label.setIconTextGap(10);
c.add ( label );

Toolkit tk = Toolkit.getDefaultToolkit();
Dimension screen = tk.getScreenSize();
int screenHeight = (int)screen.getHeight();
int screenWidth = (int)screen.getWidth();

setBounds((screenWidth/2) - this.getWidth()/2, (screenHeight/2) - this.getHeight()/2, 150, 150);
//setBackground ( Color.white );????Dont work!!
setResizable(false);
setVisible(true);
}
}
-----------------------------------------------------------

Any help would be very appreciated...

Thx Peter.

Hi,

what happens when you put:
this.setBackground ( Color.white );

Rgrds,

Do you want the background in the JLabel white, or the JFrame?

 

[petold]

"this.setBackground ( Color.white );"

Nope, tried that.....dont work.

"Do you want the background in the JLabel white, or the JFrame?"

I guess it is the JFrame that souhld be white.

More suggestions?

How about setOpaque(true) as well ?

I think what happens is that the layout manager overlays the frame background with a container. If you do this.setBackground(Color.red) you'll see the red flash briefly while the frame is building, and (at least on mine) a thin stripe of red at the bottom afterwards.

If you do setLayoutManager(null) then setting the background works.

Another workaround is to create a JPanel to cover the entire frame and set all your components on it rather then directly on the frame. Then set the background color of the panel.
