setBackground not working in Swing or AWT

I tried to change the background color of the JLabel control.

I tried lots of time, gone through JAVA documentation but it doesn’t helped much. After digging i found that few controls in JAVA have transparent background color and therefore controls having transparent background does not work for the setBackground() property.

To set the background color of such controls, we need to explicitly set the Opaque to true.

JLabel lblMousePointer.setBackground(Color.white);

lblMousePointer.setOpaque(true);
