Study Notes
Abstract Window Toolkit (AWT)
- Primary function is to provide a set of APIs for creating graphical user interfaces (GUIs) in Java applications.
Java Foundation Classes (JFC)
- Contains the Swing framework used to develop window-based applications.
- Primary purpose is to simplify and standardize GUI development in Java.
Swing vs AWT
- Swing components offer more functionality and flexibility than AWT components.
- Lightweight components (Swing) consume less memory and provide better performance compared to heavyweight components (AWT).
Component Characteristics
- Lightweight components do not depend on the native platform's GUI, enabling a consistent look across different environments.
- PL&F (Pluggable Look and Feel) permits changing the GUI's appearance without altering functionality.
User Interface Features
- Swing components include features that help create a lighter user interface, enhancing user experience.
- Term "cross-platform" describes Swing components' ability to be used across various platforms seamlessly.
Swing Architecture
- "Modular-based architecture" refers to Swing's capabilities to integrate with customized implementations and frameworks efficiently.
- Swing's properties can be modified at runtime without needing to rewrite application code, enhancing flexibility.
Design Concepts
- Swing follows the Model-View-Controller (MVC) design concept, enabling components to change independently without impacting others.
- Key difference between AWT and Swing components lies in the lightweight nature of Swing, making it more versatile.
Component Hierarchies
- The root of the visual component class hierarchy in JFC is the JComponent class.
- JComponent class contains functionality for rendering, layout, and event handling in Swing components.
MVC Pattern
- In the MVC pattern, the controller acts as the intermediary between the model and view, facilitating communication and updates among them.
