我正在用 JAVA 中的 Netbeans 制作 GUI。我的想法是这样的：

JFrame -> contains a JPanel -> call a JDialog.

                            -> call a second JDialog

这个想法是我想在第一个 JDialog 中阅读一些内容，当用户完成这个 JDialog 时，他按下一个按钮。这个 JDialog dispose() 和 JPanel 调用另一个 JDialog。

我的想法类似于 Netbeans 中的项目向导或类似的东西。

问题是：GroupLayout 一次只能与一个 Container 一起使用。

这是我的代码：

public class SubjectsPanel extends javax.swing.JPanel {
        private AddSubject addsubject; //Is an own class that inherites from JDialog.
        private AddGroups addgroups; //Is another own class that inherites from JDialog.
        private JFrame jf;




    public SubjectsPanel(JFrame fr) {
        jf = fr;
        initComponents();
    }

    /**
     * This method is called from within the constructor to initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is always
     * regenerated by the Form Editor.
     */
    @SuppressWarnings("unchecked")
    // <editor-fold defaultstate="collapsed" desc="Generated Code">                          
    private void initComponents() {

    }

    private void addButtonActionPerformed(java.awt.event.ActionEvent evt) {                                          
        addsubject = new AddSubject(jf,true);
        addsubject.setSize(700, 350);
        addsubject.setLocationRelativeTo(this);
        addsubject.setTitle("Adding New Subject Wizard");
        addsubject.setVisible(true);
        addsubject.addWindowListener(new WindowListener() {

            @Override
            public void windowOpened(WindowEvent we) {
                throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
            }

            @Override
            public void windowClosing(WindowEvent we) {
                throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
            }

            @Override
            public void windowClosed(WindowEvent we) {
                if(addsubject.getBool()){                    
                    addgroup = new AddGroup(jf,true);
                    addgroup.setSize(700, 350);
                    addgroup.setLocationRelativeTo(this);
                    addgroup.setTitle("Adding New Group Wizard");
                    addgroup.setVisible(true);
                }
            }

            @Override
            public void windowIconified(WindowEvent we) {
                throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
            }

            @Override
            public void windowDeiconified(WindowEvent we) {
                throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
            }

            @Override
            public void windowActivated(WindowEvent we) {
                throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
            }

            @Override
            public void windowDeactivated(WindowEvent we) {
            }
        });
    }                                                
}

当然，我省略了一些我认为不相关的代码部分。问题出在 WindowListener 中，就在这里：

addgroup = new AddGroup(jf,true);
addgroup.setSize(700, 350);
addgroup.setLocationRelativeTo(this);
addgroup.setTitle("Adding New Group Wizard");
addgroup.setVisible(true);

我怎样才能做好？

对不起我的英语不好。我还尝试阅读有关 GroupLayouts 的其他问题，但我无法用它们解决。

GroupLayout一次只能与一个一起使用Container，但您可以拥有任意数量的Container实例，每个实例都有自己的GroupLayout. 在本例中，尝试添加GroupPanel.

    f.add(new GroupPanel(3));
