Introduction & Download

GUI development in Java is very verbose. While trying to build an swing application I found out it can become a real pain to just lay out your components. RAD tools a la Delphi could make the process much faster for a small application. However when the application is growing, RAD tools can become a problem since their philosophy is more copy and paste than code reuse.
The most powerful AWT layout is the GridBagLayout, that you very quickly use everywhere once you master it. However it can become quite a challenge to write a GridBagLayout that does exactly what you want in one pass. I found a not so bad utility on the web to help you build GridBagLayout graphically. But it was not free and had serious annoyances.
This tool will help you understand the GridBagLayout by allowing you to interactively build it. Once you have built it you can get the associated source code. I find it quicker to use this tool than to write the Java code directly.
You can start the application from here if you have Java Web Start. Or You can download it from here and then run it using java -jar easygridbag.jar




API use example

Use a previously saved layout in your code:

        JFrame  frame   = new JFrame("Example");
        JButton button0 = new JButton("button 0"); JButton button1 = new JButton("button 1");
        JButton button2 = new JButton("button 2"); JButton button3 = new JButton("button 3");
        JButton button4 = new JButton("button 4"); JButton button5 = new JButton("button 5");       
        JPanel  panel   = new JPanel();
        panel.add(button0); panel.add(button1); panel.add(button2); panel.add(button3);
        panel.add(button4); panel.add(button5);
        BshEasyGridBag.getInstance().setGridBagLayout(panel, Example.class.getResourceAsStream("test.bsh"));


You can report bugs to . If you make any modification to the code, I would be glad to hear from you. I can also set up a developer account on the project if you want to.
