我正在尝试将以下JLayeredPane实现到我的代码中，但它似乎没有出现 - 即使它在另一个类中完美运行。有没有办法让它在我的主类中工作，或者调用另一个类来使它工作。 bgPanel类有一个带有JLayeredPane的棋盘图像和令牌图像，我希望看到它出现在已经包含其余GUI的主JFrame上。
JLayered Pane：
JLayeredPane LPane;
{
LPane = new JLayeredPane();
frame.getContentPane().add(LPane);
JLabel board = new JLabel(new ImageIcon("/Users/gavincoll/Documents/workspace
/MonopolyStarboy/src/monopoly-board-blank.jpg"));
board.setBounds(7,50, 700, 700);
LPane.add(board, new Integer(1));
}
