  2. Beans Binding • Specification is in JSR 295. • Is used to synchronized properties between two objects. • Beans binding now fully support matisse GUI Builder (make easier for developer for binding data). • There are binding source and target. • Update strategies: Read/Write, Read-Only, Read-Once • If you want to synchronize properties of two objects but they have different types you have to create Converter. • Use Validator to filter binding’s value from target.

  3. Beans Binding (cont.) • General Data flow Converter Source Target Validator Converter

  4. Beans Binding (cont.) • Extends org.jdesktop.beansbinding.Converter<S,T> to create new Converter. S is source type, and T is target type. • Override convertForward(S value):T to converts a value from the source type to the target type. • Override convertReverse(T value):S to converts a value from the target type to the source type. • Please learn my tutorial at : http://scc-ub.googlecode.com/files/tutorial.photomanager.pdf.zip ,source code available at : http://scc-ub.googlecode.com/files/PhotoManager.zip

  5. Beans Binding (cont.) • To create a new Validator you have to extends org.jdesktop.beansbinding.Validator<T>. T is target type. • Override validate(T value):Validator.Resultto define validation procedure.

  6. Beans Binding (cont.) • Example : • When several items in Jlist is selected, the JComboBox will automatically populated. • If JTextField ‘s value will be changed according to selected item in JComboBox Demo available at http://eriq.lecture.ub.ac.id/files/2011/03/BeansBindingDemo.zip

  7. DnD GUI Component GUI Component DragSource DropTarget Transferable (data)

  8. DnD (cont.) • DnD Constants • ACTION_NONE -- no action taken • ACTION_COPY -- the DragSource leaves the data intact • ACTION_MOVE -- the DragSource deletes the data upon successful completion of the drop • ACTION_COPY or ACTION_MOVE -- the DragSource will perform either action requested by the DropTarget • ACTION_LINK or ACTION_REFERENCE -- a data change to either the source or the destination propagates to the other location

  9. DnD (cont.) • Draggable Component

  10. DnD (cont.) • Flow

  11. Look n Feel • Programmatically : use UIManager class. • Non-Programmatically : use --cp:plook_and_feel_jar_path –laflook_and_feel_class_name • Sample code available at http://eriq.lecture.ub.ac.id/files/2011/03/LookAndFeelDemo.zip

  12. Create Installer & Executable • Launch4J , Jsmooth, etc is tool to create executable for java apps in windows. • InnoSetup, NSIS, etc is used to create windows installer. • Tools above are free for non-commercial or commercial use. • Launch4j : http://launch4j.sourceforge.net • Jsmooth : http://jsmooth.sourceforge.net • InnoSetup :http://www.jrsoftware.org/isinfo.php • NSIS : http://nsis.sourceforge.net

  13. Useful Components • JDIC (JDesktop Integration Component) Project : http://java.net/projects/jdic/ • SwingX (Extended Swing Component) : https://swingx.dev.java.net • SwingLabs : http://swinglabs.org
