Question

I am trying to create a pdf viewer but I can’t separate view from tabbed pane. I tried everything but not success,

• I tried adding JSplit pane, not it didn’t work. (I don’t need to add it now, just need to expand the right side panel.
• And I tried adjusting size of panels using setSize(x, y). But it didn’t work either.

Here is a screen shot:

Here some code:

class Main
{   
    public static void main(String args[]){
        JFrame frame = new JFrame("Pdf Reader");
        frame.setJMenuBar(new MenuBar());
        frame.getContentPane().add(new ToolBar(), BorderLayout.NORTH);
        frame.getContentPane().add(new LeftPanel(), BorderLayout.CENTER);

        frame.getContentPane().add(new ViewPanel(), BorderLayout.EAST);
        frame.setVisible(true);
        frame.setSize(1000, 700);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
}

class LeftPanel extends JPanel
{
    private JTabbedPane tabs;
    private JPanel panel1;
    private JPanel panel2;
    private JPanel panel3;
    private JPanel panel4;

    public LeftPanel(){
        addTabs();  
    }

    public void addTabs()
    {   
        tabs = new JTabbedPane();

        panel1 = new JPanel();  
        tabs.addTab("Thumbnails", panel1);

        panel2 = new JPanel();
        tabs.addTab("Annotations", panel2);

        panel3 = new JPanel();
        tabs.addTab("Bookmarks", panel3);

        panel4 = new JPanel();
        tabs.addTab("Search", panel4);

        setLayout(new GridLayout(1, 1));

        add(tabs, BorderLayout.CENTER);
    }
}

class ViewPanel extends JPanel
{
    private JLabel viewLabel;

    public ViewPanel(){

        viewLabel = new JLabel("Just a view...............................");

        add(viewLabel);
    }
}

Well, this is how I solved the problem.

//frame.getContentPane().add(new LeftPanel(), BorderLayout.CENTER);
JSplitPane pane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, new LeftPanel(), new ViewPanel());
frame.getContentPane().add(pane);
frame.setVisible(true);
frame.setSize(1000, 700);
//frame.pack();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

And this worked out well.
