mport java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;

public class BrowserFrame extends JFrame{
    private JLabel lblImage;
        private JButton jbtnBack, jbtnRefresh, jbtnFwd, jbtnExec, jbtnStop;
        private JTextArea jtaQuery;
        private JTabbedPane jtpResults;
        private JTree jTree1, jTree2;
        private CreateMenus menus;

        private JScrollPane sp;

    public BrowserFrame() {
                super("Browser Frame");
                initComponents();

                /*
        Icon dbImage = new ImageIcon("Globe.gif");
        lblImage = new JLabel();
        lblImage.setIcon(dbImage);*/
                setSize(900, 600);
                setVisible(true);

        }

        public void initComponents()
        {
                jbtnBack = new JButton();
                jbtnRefresh = new JButton();
                jtaQuery = new JTextArea();
                sp = new JScrollPane();
                jbtnFwd = new JButton();
                jbtnExec = new JButton();
                jbtnStop = new JButton();
                jtpResults = new JTabbedPane();
                jTree1 = new JTree();
                jTree2 = new JTree();
                menus = new CreateMenus();


                //set the Layout to null, so u can add your components whenever u want.
                getContentPane().setLayout(null);
                //sets the default font to Arial
                setFont(new Font("Arial", 0, 10));

                //sets icon for Back button and place it on the JForm
                jbtnBack.setIcon(new ImageIcon("images//stock-go-back.png"));
                jbtnBack.setHorizontalTextPosition(SwingConstants.CENTER);
                getContentPane().add(jbtnBack);
                jbtnBack.setBounds(20, 20, 70, 60);

                jbtnRefresh.setIcon(new javax.swing.ImageIcon("images//stock-refresh.png"));
                jbtnRefresh.setHorizontalTextPosition(javax.swing.SwingConstants.CENTER);
                getContentPane().add(jbtnRefresh);
                jbtnRefresh.setBounds(100, 20, 80, 60);

                jtaQuery.setLineWrap(true);
                sp.setViewportView(jtaQuery);
                getContentPane().add(sp);
                sp.setBounds(280, 20, 330, 60);

                jbtnFwd.setIcon(new javax.swing.ImageIcon("images//stock-go-forward.png"));
                jbtnFwd.setHorizontalTextPosition(javax.swing.SwingConstants.CENTER);
                getContentPane().add(jbtnFwd);
                jbtnFwd.setBounds(190, 20, 70, 60);

                jbtnExec.setIcon(new javax.swing.ImageIcon("images//stock-execute.png"));
                getContentPane().add(jbtnExec);
                jbtnExec.setBounds(620, 20, 70, 60);

                jbtnStop.setIcon(new javax.swing.ImageIcon("images//stock-stop.png"));
                jbtnStop.setHorizontalTextPosition(javax.swing.SwingConstants.CENTER);
                getContentPane().add(jbtnStop);
                jbtnStop.setBounds(700, 20, 70, 60);

                jtpResults.setBorder(new javax.swing.border.BevelBorder(javax.swing.border.BevelBorder.RAISED));
                getContentPane().add(jtpResults);
                jtpResults.setBounds(30, 100, 560, 390);

                getContentPane().add(jTree1);
                jTree1.setBounds(600, 100, 230, 170);

                getContentPane().add(jTree2);
                jTree2.setBounds(600, 280, 230, 190);
                setJMenuBar(menus.doIt());


        }


    public static void main(String args[]) {

                BrowserFrame app = new BrowserFrame();
                app.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
}

kao sto vidite postoji klasa CreateMenus

ovo je CreateMenus klasa

Code:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;

public class CreateMenus extends JFrame
{

        private JMenuBar jMBar;
        private JMenu fileMenu, editMenu, toolsMenu, helpMenu;
        private JMenuItem newConnectionItem, openScripItem, closeConnectionItem, exitItem;
        private JMenuItem cutItem, copyItem, pasteItem, selectAllItem;
        private JMenuItem toolsItem1, toolsItem2;
        private JMenuItem contentsItem, mySqlRefItem, aboutItem;
        public int counter = 0;



        public CreateMenus()
        {
                createComponents();
                addActionListenersToMenuItems();

        }

        private void createComponents()
        {

                makeMenuItems();
                makeMenus();
                addActionListenersToMenuItems();
        }

        private void makeMenuItems()
        {
                newConnectionItem = new JMenuItem("New Connection...");
                newConnectionItem.setMnemonic('N');

        }

        private void makeMenus()
        {
                jMBar = new JMenuBar();
                fileMenu = new JMenu();
                editMenu = new JMenu();
                toolsMenu = new JMenu();
                helpMenu = new JMenu();

                fileMenu.setText("File");
                fileMenu.setMnemonic('F');
                fileMenu.add(newConnectionItem);
                editMenu.setText("Edit");
                editMenu.setMnemonic('E');
                toolsMenu.setText("Tools");
                toolsMenu.setMnemonic('T');
                helpMenu.setText("Help");
                helpMenu.setMnemonic('H');

        }

        private void addActionListenersToMenuItems()
        {
                newConnectionItem.addActionListener(
                new ActionListener(){

                        public void actionPerformed(ActionEvent e)
                        {
                                Options optionsFrame = new Options();
                        }

                });

        }



        public JMenuBar doIt()
        {
                jMBar.add(fileMenu);
                jMBar.add(editMenu);
                jMBar.add(toolsMenu);
                jMBar.add(helpMenu);

                return jMBar;

        }

}

i jos jedna klasa
Options

Code:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class Options extends JFrame
{
    ConnectionParameters connParam;
    ConnectionTree connTree;

    JPanel treePanel;

    public Options()
    {
        super("Options Connection");

        Container c = getContentPane();
        c.setLayout( new FlowLayout() );

        connTree = new ConnectionTree();
        c.add(connTree);

        connParam = new ConnectionParameters();
        c.add(connParam);






        setSize(566, 452);
        setVisible(true);

    }

     public static void main(String args[]) {
         LookAndFeel lf = UIManager.getLookAndFeel();

    // Install a different look and feel; specifically, the Windows look and feel
    try {
        UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
    } catch (InstantiationException e) {
    } catch (ClassNotFoundException e) {
    } catch (UnsupportedLookAndFeelException e) {
    } catch (IllegalAccessException e) {
    }
       Options window = new Options();

        window.setTitle("Options Connection");
      window.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
        window.pack();
        window.show();
    }
   }

ok a sada problem:
Kada kliknem na menu new Connection kao da sam dva puta kliknuo... nije mi jasno zasto.
morao sam da stavim if sa counter-om da bi se samo jednom OptionsFrame pojavljivao.
da li neko zna u cemu je problem..

hvala puno
