Edit: I know I posted it in wrong section :(

I already flagged it, no need to vote down...

My original idea was to make small FileManager for specific folders.

I added toolbar with some buttons that dont work yet except for "open file" button.

However I encountered another problem that I am yet to fix.

private static void display() 

        {

            String iconPath = "C:\alta\eclipse\pseudo-1C\icons\";

            String path = "C:\alta\eclipse\pseudo-1C";

            PanelBrowser browser = new PanelBrowser(new File(path));



            JFrame f = new JFrame("Pseudo-1C Manager");

            f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);



            JToolBar toolbar = new JToolBar();

            toolbar.setRollover(true);



            toolbar.addSeparator(); 



            ImageIcon RefreshIcon = new ImageIcon(iconPath+"refresh.png"); 

            Image Rimage = RefreshIcon.getImage(); // transform it 

            Image refreshNewImg = Rimage.getScaledInstance(20, 20,  java.awt.Image.SCALE_SMOOTH); // scale it the smooth way  

            RefreshIcon = new ImageIcon(refreshNewImg);  // transform it back



            JButton refresh = new JButton(RefreshIcon);

            toolbar.add(refresh);



            toolbar.addSeparator();





            ImageIcon DirIcon = new ImageIcon(iconPath+"folder.png"); //icon folder is named "pseudo-1C icons"

            Image Dimage = DirIcon.getImage(); // transform it 

            Image DirNewImg = Dimage.getScaledInstance(20, 20,  java.awt.Image.SCALE_SMOOTH); // scale it the smooth way  

            DirIcon = new ImageIcon(DirNewImg);  // transform it back



            JButton folder = new JButton(DirIcon);

            toolbar.add(folder);



            toolbar.addSeparator();

            toolbar.addSeparator();

            toolbar.addSeparator();

            toolbar.addSeparator();

            toolbar.addSeparator(); 

            toolbar.addSeparator();

            toolbar.addSeparator();

            toolbar.addSeparator();

            toolbar.addSeparator(); 

            toolbar.addSeparator();

            toolbar.addSeparator(); 

            toolbar.addSeparator();



            String folders = new String {"A", "B", "C"};

            JComboBox<String> folderList = new JComboBox<>(folders);

            folderList.addActionListener( new ActionListener() {

                @Override

                public void actionPerformed(ActionEvent e) {

                    JComboBox cb = (JComboBox)e.getSource();

                    String foldername = (String)cb.getSelectedItem(); 

                    System.out.println("Folder "+foldername+" was chosen");



                    ChangeFolder(foldername);

                }

              } );

            toolbar.add(folderList);





            toolbar.setFloatable (false);

            Container contentPane = f.getContentPane();

            contentPane.add(toolbar, BorderLayout.NORTH);

            f.add(new JScrollPane(browser) 

                {

                    @Override

                    public int getVerticalScrollBarPolicy() 

                        {

                            return JScrollPane.VERTICAL_SCROLLBAR_NEVER;

                        } 

                });

            f.pack();

            f.setSize(4 * SIZE.width, SIZE.height);

            f.setLocationRelativeTo(null);

            f.setVisible(true);

        }   



    protected static void ChangeFolder(String name) {

        String returnfolder = name;

        return;

    }

Basically, I want to use JComboBox to switch the shown folder to the one of premade ones, yet I dont know how to do that. ActionListener responds to correct folder names, but I am not sure how to make it "refresh the page" for update.
I used this as base for my project:

I provided my last "fork" of code without broken parts, but with ones I got stuck with.
