DefaultFormBuilder
.
* Columns are specified before the panel is filled with components,
* rows are added dynamically. The builder is used to hold a cursor,
* to add rows dynamically, and to fill components.
* The builder's convenience methods are used to add labels and separators.* * This panel building style is recommended unless you have a more * powerful builder or don't want to add rows dynamically. * See the {@link DynamicRowsExample} for an implementation that specifies * rows before the panel is filled with components. * * @author Karsten Lentzsch * @version $Revision: 1.8 $ * * @see DefaultFormBuilder * @see PlainExample * @see RowCounterExample * @see DynamicRowsExample */ public class DefaultFormBuilderExample { private JTextField identifierField; private JTextField ptiField; private JTextField powerField; private JTextField sField; private JTextField daField; private JTextField diField; private JTextField da2Field; private JTextField di2Field; private JTextField rField; private JTextField dField; private JComboBox locationCombo; private JTextField kFactorField; public static void main(String[] args) { try { UIManager.setLookAndFeel("com.jgoodies.plaf.plastic.PlasticXPLookAndFeel"); } catch (Exception e) { // Likely PlasticXP is not in the class path; ignore. } JFrame frame = new JFrame(); frame.setTitle("Forms Tutorial :: Default Form"); frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); JComponent panel = new DefaultFormBuilderExample().buildPanel(); frame.getContentPane().add(panel); frame.pack(); frame.setVisible(true); } // Component Creation and Initialization ********************************** /** * Creates and intializes the UI components. */ private void initComponents() { identifierField = new JTextField(); ptiField = new JTextField(); powerField = new JTextField(); sField = new JTextField(); daField = new JTextField(); diField = new JTextField(); da2Field = new JTextField(); di2Field = new JTextField(); rField = new JTextField(); dField = new JTextField(); locationCombo = createLocationComboBox(); kFactorField = new JTextField(); } /** * Creates and returns a combo box for the locations. * * @return a combo box for three locations */ private JComboBox createLocationComboBox() { return new JComboBox( new String[] { "Propeller nut thread", "Stern tube front area", "Shaft taper" }); } // Building *************************************************************** /** * Builds the flange editor panel. * Columns are specified before components are added to the form, * rows are added dynamically using the {@link DefaultFormBuilder}.
