Java Swing GUI Components

Overview

Java Swing is a set of APIs for creating graphical user interfaces (GUIs) in Java. It is part of the Java Foundation Classes (JFC) and is built on top of the Abstract Window Toolkit (AWT).

Key Components

JFrame:

• A top-level container for a GUI application
• Provides a window with a title bar, borders, and a content pane

JPanel:

• A generic container for GUI components
• Can be added to a JFrame or another JPanel

JComponent:

• The base class for all GUI components in Swing
• Provides basic functionality such as size, location, and event handling

GUI Components

Labels and Buttons

• JLabel: displays text or an image
• JButton: a clickable button with text or an icon

Text Components

• JTextField: a single-line text input field
• JTextArea: a multi-line text input field
• JTextPane: a styled text component

Lists and Tables

• JList: a list of items that can be selected
• JTable: a table with rows and columns of data

Menus

• JMenuBar: a menu bar with multiple menus
• JMenu: a dropdown menu with menu items
• JMenuItem: an individual menu item

Event Handling

• ActionListener: an interface for handling button clicks and other events
• MouseListener: an interface for handling mouse clicks and movements
• KeyListener: an interface for handling keyboard input

Layout Managers

• BorderLayout: a layout manager for arranging components in a container
• FlowLayout: a layout manager for arranging components in a row or column
• GridLayout: a layout manager for arranging components in a grid

Threading and Updates

• Event-Dispatching Thread (EDT): the thread responsible for updating the GUI
• SwingUtilities.invokeLater(): a method for scheduling GUI updates on the EDT
