extends java.lang.Object

This is an example for a GUI from a tutorial for an SWT layout manager. Apart from its relative complexity, its main features are (a) the use of a panel cell for the 'Owner Info' part of the GUI shown in the figure below, and (b) baseline alignment. Note that the panel cell is needed only because the GUI requires a panel with a titled border.

        // Utility function for creating a JTextField with border
        public static JTextField createTextField(String text,int len)
        {
                JTextField ed=new JTextField(text,len);
                ed.setBorder(BorderFactory.createLoweredBevelBorder());
                return ed;
        }
        public static PanelCell ownerInfoPanelCell()
        {
                // Create the cell for owner info editors

                // The panel
                JPanel panel=new JPanel();


                Border border=BorderFactory.createEtchedBorder();
                border=BorderFactory.createTitledBorder(border,"Owner Info");
                panel.setBorder(border);

                // Create components
                JLabel name=new JLabel("Name");
                JLabel phone=new JLabel("Phone");
                JTextField nameEditor=createTextField("Jane Doe",10);
                JTextField phoneEditor=createTextField("555-3245",10);

                // First row
                rows.newRow().add(name,nameEditor);

                // First row
                rows.newRow().add(phone,phoneEditor);

                CellGrid grid=rows.createCellGrid();

                // Baseline alignment
                grid.alignBaseline(name,nameEditor);
                grid.alignBaseline(phone,phoneEditor);

                // Create and return the panel cell
