Windows Programming with Swing

- 2. Java Foundation Classes? Set of Java Class Libraries provides as part of J2SE Support building GUI and graphics functionality for Java based Client Application Run on Microsoft Platform and others like Mac OSX and Linux Easily deployed over the web Rich clients for web services
- 3. Features of JFC Abstract Windowing Toolkits Java 2D Swing GUI Components Accessibility Internationalization
- 4. MVC Architecture Design pattern to Swing UI for JFC Used for constructing entire UI Components Each component has a Model, a View and a Controller. The model, view ,and controller pieces can change even while the component is in use.
- 5. MVC Design Pattern Model Controller View Inform the view to update visual Read the contents Update the contents Inform view of state change
- 6. What MVC means? Model is the piece that represents the state and low level behavior of the component. (stored the data or stage of object) View is the piece that manage the visual display of the state represented by the model Controller is the piece that manages user interaction with the model.(handle the event)
- 7. Benefits using MVC To divded large program to views of documents. A view provides a window into document Multiple views can provide multiple windows into the document.
- 8. Swing Programming AWT is the heave weight component and it has a peer object for the native GUI When the components are created they take help of the underlying O/S Java offers Light weight components that do not have a peer object. It now popular by Swing UI components
- 9. Why Swing? Uses fewer system resources Add a lot of more sophisticated components Tailor the Look and Feel of program and Extensing of Existing Components for - Layout Management - Event handling - Thread and Swing - Printing ….etc
- 10. Swing Basic Swing is set of packages build on top of the AWT with number of prebuild classes(over 250 classes and 40UI components) All swing UI components are started with J for use the terms JFC and Swing interchangeabily
- 11. Structure of Swing Components JContainer Classes JComponent Classes All Swing Components
- 12. Swing Components Windows Menus AbstractButton Panels Layouts Icons Borders Toolbars Labels Buttons List Boxes Combo Boxes Check Boxes Tables Trees
- 13. Sub Classes of the JComponent Class JComponent is the superclass of all swing components. All the components begin with the letter ‘J’. JComponent has the following subclasses: AbstractButton class JButton & JLabel class JButton JLabel JComboBox class JCheckBox class Jlist Jmenu JPopupMenu JProgressBar JScrollBar JRadioButton Jseparator Jtable JTextComponent JToolBar JTree
- 14. Swing Packages Swing Package Description javax.swing Contains components, adapters, component models and interfaces. It is the highest-level swing package. javax.swing.basic Contains the user interface classes that implement the look and feel for swing components. javax.swing.border Declares the border interface, and classes defining the specific border styles. javax.swing.plaf Contains the plugable look and feel API. javax.swing.table Contains the interfaces and classes supporting the swing table component. javax.swing.text Contains the support classes for the swing document framework. javax.swing.event Defines the events and event listeners. javax.swing.tree Provides classes and interfaces that support the JTree component. javax.swing.undo Provides support classes for undo/redo operations.
- 15. Swing Event Handling For a Java program to run, the interface should be made receptive to user events Swing handles events with a set of classes called ‘event listeners’ javax.swing.event package defines a set of event listening interfaces and event classes so that they can used with Swing components There are various events defined in the javax.swing.event package, such as: ChangeEvent DragEvent ListDataEvent ListSelectionEvent TableModelEvent TableColumnEvent
- 16. Look and Feel Swing is a real improvement to the AWT, since it supplies rich set of platform GUI components Platform independence means the components within it are supported across all Java ports Enables the look and feel of the components to be easily tailored This is called as Pluggable Look and Feel (L&F) of the swing components This helps us to create applets and applications that have a look and feel independent to the window platform in which they are executed
- 17. Look and Feel Cont; The look and feel consists of the way the program is presented to the user (looks) & the way user interacts with it (feels). Swing provides the capability to change the look and feel of the applet or application. Swing components are not tied to GUI components. It is because of this that we can create applets or applications that will use a specific look and feel. Look and feel is a function of view and controller.
