Java Swing GUI Overview

Overview of Swing GUI

• Definition: Swing is a graphical user interface (GUI) toolkit for the Java programming language.
• Part of: Java Foundation Classes (JFC)
• Released: 1997
• Purpose: Provides a set of classes and interfaces for creating GUI components and managing GUI events.

Key Features of Swing GUI

• Platform independence: Swing GUI components are designed to work on any platform that supports Java.
• Customizable: Swing components can be customized to fit the look and feel of different platforms.
• Extensive widget set: Includes a wide range of GUI components, such as buttons, text fields, tables, and trees.
• Event-driven programming: Swing GUI components generate events that can be handled by event listeners.

Swing GUI Components

• Top-level components:
  • JFrame: Represents a top-level window with a title bar and borders.
  • JDialog: Represents a top-level window that is dependent on another window.
  • JApplet: Represents a GUI component that can be embedded in a web page.
• Intermediate components:
  • JPanel: A generic container component that can hold other components.
  • JScrollPane: A component that provides scrolling for other components.
• Basic components:
  • JButton: A push button component.
  • JLabel: A component that displays a text or image.
  • JTextField: A component that allows the user to enter a single line of text.

Swing GUI Layout Managers

• Purpose: Layout managers are used to arrange and position GUI components within a container.
• Types of layout managers:
  • BorderLayout: Arranges components in five regions: north, south, east, west, and center.
  • FlowLayout: Arranges components in a horizontal or vertical row.
  • GridLayout: Arranges components in a grid of rows and columns.
  • GridBagLayout: A flexible layout manager that uses constraints to arrange components.
