8. Adding More Controls “Tire Size” slider “Tire Size” slider “Modernness” slider “Modernness” slider “Spoiler” checkbox “Spoiler” checkbox “Roof” checkbox “Roof” checkbox

9. Binding Controls to Values in the Table In the form, right-click the first slider and choose Bind > value. In the form, right-click the first slider and choose Bind > value. In the Binding Source drop-down list of the Binding dialog box, select masterTable. In the Binding Source drop-down list of the Binding dialog box, select masterTable. In the Binding Expression drop-down list, select selectedElement > tiresize. In the Binding Expression drop-down list, select selectedElement > tiresize. Click the Advanced tab. Click the Advanced tab. Select the Unreadable Source Value checkbox. Select the Unreadable Source Value checkbox. Click the ellipsis (...)button that is next to the Unreadable Source Value checkbox. Click the ellipsis (...)button that is next to the Unreadable Source Value checkbox.

10. Binding Controls to Values in the Table In the Incomplete Path Value dialog box, select Custom Code from the drop-down list. Then type the integer 0. In the Incomplete Path Value dialog box, select Custom Code from the drop-down list. Then type the integer 0. Right-click the checkbox and choose Customize Code. Right-click the checkbox and choose Customize Code. In white line under the bindingGroup.addBinding(binding) line, type: In white line under the bindingGroup.addBinding(binding) line, type: binding.setSourceUnreadableValue(false); binding.setSourceUnreadableValue(false); Run application and verify into Databse Run application and verify into Databse

11. Setting up a Custom Component Adding Car Preview package Adding Car Preview package Drag the CarPreview.java class (JavaBeans component) to the form Drag the CarPreview.java class (JavaBeans component) to the form Bind all the binding properties of the CarPreview component to the corresponding selectedElement attributes of the masterTable Bind all the binding properties of the CarPreview component to the corresponding selectedElement attributes of the masterTable

16. Swing Application Framework Framework Architecture. Two classes help you manage your application (one-to-one relationship): Framework Architecture. Two classes help you manage your application (one-to-one relationship): ApplicationContext ApplicationContext Application Application ApplicationContext services: ApplicationContext services: Localizable resource management Localizable resource management Task services and monitoring Task services and monitoring Event-action management Event-action management Session-state storage Session-state storage

17. From where to start All Swing Application Framework applications must subclass either the Application class or its SingleFrameApplication subclass. The SingleFrameApplication adds a default main GUI frame, retrieves and injects default resources, and uses the ApplicationContext to save and restore simple session state. Session state includes UI component location, size, and configuration.

19. Example subclasses the Application class public class BasicFrameworkApp extends Application { private JFrame mainFrame; private JLabel label; protected void startup() { mainFrame = new JFrame("BasicFrameworkApp"); mainFrame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE); mainFrame.addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent e) { mainframe.setVisible(false); exit();}}); label = new JLabel("Hello, world!"); mainFrame.add(label);mainFrame.pack();mainFrame.setVisible(true);} public static void main(String[] args) { Application.launch(BasicFrameworkApp.class, args); } }

20. Example subclasses the SingleFrameApplication class public class BasicSingleFrameApp extends SingleFrameApplication { JLabel label; protected void startup() { getMainFrame().setTitle("BasicSingleFrameApp"); label = new JLabel("Hello, world!"); label.setFont(new Font("SansSerif", Font.PLAIN, 22)); show(label);} public static void main(String[] args) { Application.launch(BasicSingleFrameApp.class, args); }}
