setBackground : Java Glossary
setBackground( 0xrrggbb ) sets the background colour of a component the
next time it is painted. setForeground sets the colour of text painted on it. Note it
is setBackground not setBackGround.
- When you use Swing, use contentPane.setBackground not
or nothing will happen.
- In a paintComponent method, you use Color
c = getBackground(); graphics.
setColor( c ); to load up the pen with colour to paint the
background. Doing a plain setBackground has no effect.
- Sometimes buttons in some L&Fs will ignore your setBackground. In that case use setContentAreaFilled( false ) then paint your own background in
