摆动JComponents对齐形式

Question

如何使用Swing将这些JComponents与"内容"窗格中心的"表单"对齐...

        panel1.add(l1);
        panel1.add(c1);
        panel1.add(l2);
        panel1.add(c2);
        panel1.add(b4);
        panel1.add(b5);
        frame1.getContentPane().add(panel1);

请帮我

您首先阅读容器中的Laying Out Components教程怎么样？我滥用了这个说法但是,总是不止一种方法给猫皮肤

下面是一个使用多余的例子BoxLayout,并setAlignmentX(...)在JComponent实例-

public final class StackComponentsDemo {
    public static void main(String[] args){
        SwingUtilities.invokeLater(new Runnable(){
            @Override
            public void run() {
                createAndShowGUI();             
            }
        });
    }

    private static void createAndShowGUI(){
        final JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        final JPanel panel = new JPanel();
        panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));

        panel.add(new DisabledJButton());
        panel.add(new DisabledJButton());
        panel.add(new DisabledJButton());
        panel.add(new DisabledJButton());
        panel.add(new DisabledJButton());

        frame.add(panel);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }

    private static final class DisabledJButton extends JButton{
        public DisabledJButton(){
            super("Disabled");
            setEnabled(false);
            setAlignmentX(Component.CENTER_ALIGNMENT);
        }
    }
}
