How to change the background color on a Java panel?

Question

Right now, the background I get is a grey. I want to change it to black. I tried doing something like setBackground(color.BLACK); but it didnt work. Any suggestions?

Answer 1

setBackground() is the right method to use. Did you repaint after you changed it? If you change it before you make the panel (or its containing frame) visible it should work

Answer 2

I think what he is trying to say is to use the getContentPane().setBackground(Color.the_Color_you_want_here)

but if u want to set the color to any other then the JFrame, you use the object.setBackground(Color.the_Color_you_want_here)

Eg:

jPanel.setbackground(Color.BLUE)

Answer 3

You could call:

getContentPane().setBackground(Color.black);

Or add a JPanel to the JFrame your using. Then add your components to the JPanel. This will allow you to call

setBackground(Color.black);

on the JPanel to set the background color.

Answer 4

I am assuming that we are dealing with a JFrame? The visible portion in the content pane - you have to use jframe.getContentPane().setBackground(...);
