Study Notes

Overview of Swing

Swing is a class set offering more powerful, flexible GUI components than AWT.
Components in Swing include buttons, check boxes, labels, tabbed panes, scroll panes, trees, and tables.
Swing components are entirely platform-independent, enhancing portability.

Architectural Structure

Swing components are built on top of AWT, leading to over 250 classes and 40 UI components.
Key Swing components include:
- AbstractButton: Super-class for buttons.
- JApplet: The Swing version of Applet.
- JButton: Push button class.
- JCheckBox: Check box class.
- JComboBox: Combines drop-down list and text field.
- JLabel: Label class.
- JRadioButton: Radio button class.
- JScrollPane: Scrollable window encapsulation.
- JTabbedPane: Tabbed window control.
- JTable: Table-based control.
- JTextField: Text field class.
- JTree: Tree-based control.

Features of Swing

Borders: Customizable drawing of borders around components via the setBorder() method.
Graphics Debugging: Enabled through setDebuggingGraphicsOptions to visualize drawing operations.
Mouseless Operation: Simplified connection of keystrokes to components for easier interaction.
Tooltips: Utilization of setToolTipText for explanatory pop-ups when hovering over components.
Easy Scrolling: Scrolling functionality for components, surpassing AWT capabilities.
Pluggable Look and Feel: Ability to alter the appearance of applications to a standard style (Windows, Motif, or Metal).
