public class GridBagHelper
extends java.lang.Object

GridBagHelper is a class that makes it easier to create form user interfaces. Using GridBagLayout and this class you can easily create forms, reducing code repeitition. For example to create a form which lets the user fill in two text field entries:

 JPanel formPanel = new JPanel();
 GridBagLayout gridbag = new GridBagLayout();
 GridBagConstraints c = new GridBagConstraints();
 formPanel.setLayout(gridbag);
           
 c.weightx = 1.0;
 c.ipadx = 5;
 c.anchor = GridBagConstraints.WEST;
          
 JTextField initialCapitalTextField = 
    GridBagHelper.addTextRow(formPanel, "Initial Capital", "", gridbag, c, 
                             10);
 JTextField tradeCostTextField =
    GridBagHelper.addTextRow(formPanel, "Trade Cost", "", gridbag, c, 5);
