extends java.lang.Object

This is another example of using GridRows to create a grid. It uses setRowMargins to set left and right margins.

The example has been taken from a tutorial for FormLayout.

        // A utility function to create a textfield with
        // specified number of columns and a bevel border.
        public static JTextField createTextField(int n)
        {
                JTextField ed=new JTextField(n);
                ed.setBorder(BorderFactory.createLoweredBevelBorder());
                return ed;
        }
        // A utility function to create a row of a 
        // separator of fixed height with a leading label.
        public static Row createNamedSeparator(String text)
        {
                Row row=new Row(Cell.JUSTIFIED,Cell.CENTER);
                row.add(new JLabel(text));
                JSeparator sep=new JSeparator();
                row.add(sep);
                Dimension d=sep.getPreferredSize();
                sep.setMaximumSize(new Dimension(Cell.MAX,d.height));
                return row;
        }
        // A utility function to add a label
        // and an editor to a GridRow object.
        public static void addLabelAndEditor(
                        GridRow row, String text, int n)
        {
                row.add(Cell.RIGHT,Cell.CENTER,new JLabel(text));
                row.add(Cell.NO_ALIGNMENT,Cell.CENTER,createTextField(n));

                // and the separator spans all the four columns of the grid.
                rows.newRow().add(createNamedSeparator("General")).span(4);

                // Row 2 The 'Company' label and editor.
                GridRow row=rows.newRow();
                addLabelAndEditor(row,"Company",20);

                // It is enough to add a vertical gap in
                // the first column. The trailing blanks in 
                // the row are automaticall created.
