Advanced Java Programming

This tutorial focuses on advanced Java programming concepts, specifically using Swing for GUI development. It delves into Beans Binding, detailing how to synchronize properties between objects, implement update strategies, and use converters for different types. The tutorial also explores Drag-and-Drop (DnD) functionality, providing insights on creating interactive applications. You'll learn to create validators, utilize examples with JComboBox and JList, and discover tools for creating executable applications and installers. Access resources and sample codes to enhance your Java skills.

  1. Informatics– University of Brawijaya Advanced Java Programming Swing [part.2] Eriq Muhammad Adams J eriq.adams@ub.ac.id | http://eriq.lecture.ub.ac.id

  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
