I've spent the past few days looking up Java window transitions that work with Swing components & containers (JFrame, JPanel, etc.). Yes, there are packages such as JavaFX which includes a Timeline & Transition framework. I also came across these: Trident: Project Kenai — We're More Than Just a Forge FRC: Filthy Rich Clients (find the Animation jar (org.jdesktop.animation)) However, I've been impatient lately ...
JTree is a Swing component that displays hierarchical data in a tree structure. The screen-shot below depicts a tree component: Figure: A tree component in Java This article will focus on how to implement such a tree component in Java, by walking through basic concepts to develop an interesting sample application. Fundamental concepts about Tree component Node: A tree displays data vertically in rows, ...
Registered event listeners are notified for the event received by objects in swing delegation event model. Event receiver is a component in most cases. • Event Types: ActionEvent, KeyEvent, MouseEvent, WindowEvent etc. • Event Processors: JButton, JList etc. • EventListeners: ActionListener, ComponentListener, KeyListener etc. Swing delegation event model
Shared behavior between different user interfaces components are implemented by “Swing Action Architecture”. Like tool bar buttons and menu items perform same actions. All the components are disabled when an action is disabled. Java Code: Swing Action Architecture class FileAction extends AbstractAction { //Constructor FileAction(String name) { super(name); } public void actionPerformed(ActionEvent ae){ //add action logic here } } JMenu fileMenu ...
class FileAction extends AbstractAction { //Constructor FileAction(String name) { super(name); } public void actionPerformed(ActionEvent ae){ //add action logic here } } JMenu fileMenu

Swing contains a rich set of components as compared to AWT. They are purely build in Java and has following benefits as compared to AWT. • Swing contains extra components like JTree, JTable etc. • They can change skin based on current look and feel. • They follow the MVC design pattern and are more flexible. • Swing provided light weight components. • Swing provides double buffering. • Swing provides paint debugging. Swing has following ...
Swing provides a very flexible widget, it is the JTable. Using the JTable component, you can display tabular data in form of columns and rows, plus allowing the user to edit and save the data if needed. Why need to use a model The Java Swing architecture separates the view and the model of a UI component. The view is how the component is drawn on the screen and gets changed if the user interacts with the component. The model is how data is structured and organized. The ...

AWT (the Abstract Windowing Toolkit) was the first Java GUI toolkit, introduced with JDK 1.0 as one component of the Sun Microsystems Java standard. The relatively primitive AWT wrapped Java code around native (operating system-supplied) objects to create GUI elements, such as menus, windows and buttons. AWT was a very thin wrapper around native widgets, exposing developers to platform specific code, quirks and bugs that limited how portable and native-looking applications could be across different ...
