Study Notes
Graphics Programming Overview
- Focus on writing Java programs with graphical user interfaces (GUIs).
- Learn to manipulate window sizes, positions, font styles, and display images.
Introducing Swing
- Initial Java GUI was based on AWT (Abstract Window Toolkit) for basic programming.
- AWT's slogan: “Write Once, Run Anywhere,” yet led to "write once, debug everywhere" criticism from developers.
- Swing was developed in collaboration with Netscape's IFC (Internet Foundation Classes) approach, which painted UI elements onto blank windows.
- Swing became part of Java’s standard library starting from Java SE 1.2 and is part of Java Foundation Classes (JFC).
- Key advantages of using Swing:
- Rich set of UI elements available.
- Fewer dependencies on the underlying platform, reducing platform-specific bugs.
- Consistent user experience across multiple platforms, though it may not match native controls exactly.
Creating a Frame
- A top-level window in Java is referred to as a "frame."
- The AWT library provides the Frame class; Swing utilizes JFrame, which extends Frame.
- JFrame decorations (buttons, title bar, icons) are managed by the user’s windowing system, not Swing.
- The JFrame class is located in the javax.swing package and provides various methods for customization.
- Multiple constructors available for creating JFrame instances, offering flexibility in frame setup.
