布局管理器的问题！谢谢！

Question

是一样大,而且每格都会一样大.
要重新定义大小,可以先把你的控件放到一个JPanel中,
可以用null或其它layout调好大小再把这个JPanel放进去

Answer 1

是不是把jPanel放到GridLayout的网格里面去了?
没问题的我试了:public class Panel2 extends JPanel {
    private GridLayout gridLayout1 = new GridLayout(2,2);
    private JPanel jPanel1 = new JPanel();
    private JPanel jPanel2 = new JPanel();
    private JButton jButton1 = new JButton();
    private JButton jButton2 = new JButton();
    private JPanel jPanel3 = new JPanel();
    private JCheckBox jCheckBox1 = new JCheckBox();
    private JPanel jPanel4 = new JPanel();
    private JCheckBox jCheckBox2 = new JCheckBox();    public Panel2() {
        try {
            jbInit();
        }
        catch(Exception ex) {
            ex.printStackTrace();
        }
    }
    void jbInit() throws Exception {
        this.setLayout(gridLayout1);
        jButton1.setText("jButton1");
        jButton2.setText("jButton2");
        jCheckBox1.setText("jCheckBox1");
        jCheckBox2.setText("jCheckBox2");
        this.add(jPanel1, null);
        jPanel1.add(jButton1, null);
        this.add(jPanel4, null);
        jPanel4.add(jCheckBox2, null);
        this.add(jPanel3, null);
        jPanel3.add(jCheckBox1, null);
        this.add(jPanel2, null);
        jPanel2.add(jButton2, null);
    }
}
