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.
