Study Notes
Java GUI Overview
- Java programmers use the Abstract Window Toolkit (AWT) API for creating graphical user interface (GUI) objects.
- Swing components serve as the main UI elements within Java, providing a rich set of features for GUI development.
Java Foundation Classes (JFC)
- The primary purpose of the Java Foundation Classes (JFC) is to provide a set of classes that support the development of sophisticated graphical user interfaces.
- PL&F stands for Pluggable Look-and-Feel, allowing developers to change the appearance of GUI components without altering functionality.
Swing Components
- Swing components allow mixing of AWT heavyweight and Swing lightweight components, enhancing flexibility in GUI design.
- The key difference between AWT heavyweight and Swing lightweight components is that heavyweight components are tied to a native system window, while lightweight components are drawn in memory and do not rely on native GUI.
Features and Advantages
- A key feature of Swing components includes their ability to provide a progressive and customizable user interface.
- Swing components are best described by the Model-View-Controller (MVC) architecture, which separates data, UI, and user interaction concerns.
- The main advantage of Swing components over AWT components lies in their lightweight nature and enhanced features like double buffering and more flexible painting capabilities.
Component Hierarchies and Package Details
- The root of the visual component class hierarchy in JFC is the Component class.
- Swing components are imported through the javax.swing package.
- AWT components, in contrast, are imported through the java.awt package.
Characteristics and Design Patterns
- A notable characteristic of Swing controls is their rich interactivity and operation customization, making them user-friendly.
- Swing primarily follows the MVC design pattern, promoting efficient separation and management of responsibilities within the application.
