What I did and I know it isn't correct is, I overrided the paintComponent for the paintings, so far so good.

But when I add the graphics panel to a JF...

Each of those panels is a subclass of JPanel. (Ex: JPanel gameControlPanel = new GameControlPanel(), where GameControlPanel is a class I crea...
I made a simple java game last week. At that time, one class extended Jframe and held the data (which comprised three other class, through composition) Now, I'm trying to make the same game, but with several JPanels. One panel will be the game graphics (basically the old JFrame shrunk into one panel). And there will be buttons and text ...
