What is Swing? • The Java Foundation Classes (JFC) API extends the original Abstract Window Toolkit (AWT) by adding a comprehensive set of graphical user interface class libraries. JFC/Swing components include: • Pluggable Look and Feel • Accessibility API • Java 2DTM API (Java 2 only) • Drag and Drop (Java 2 only) • AWT • Internationalization CS377A: A Programming Approach to HCI • Jan Borchers • Spring 2002
JFC/Swing GUI Components • Written in the Java programming language • Customizable look-and-feel • No reliance on the native windowing system • Incorporated in the Java 2 platform CS377A: A Programming Approach to HCI • Jan Borchers • Spring 2002
JFC/Swing GUI Components Top-Level Containers Applet Dialog Frame CS377A: A Programming Approach to HCI • Jan Borchers • Spring 2002
JFC/Swing GUI Components General-Purpose Containers Tabbed Pane Split Pane Scroll Pane Toolbar Panel CS377A: A Programming Approach to HCI • Jan Borchers • Spring 2002
