So I made my extension of JPanel and am trying to use an instance of Graphics2D in order to draw it up. It's supposed to look like a clock eventually but never mind that now. The problem is that when I implement the paintComponent(Graphics g) method I lose the background that was implemented in the initialize method. I tried moving the contents of initialize to the constructor but that doesn't help the problem. All I see is what I draw up in the paintComponent method, and the background disappears. Does paintComponent override initialize, somehow?
