1. JAVA API (GUI) Subject:T0934 / Multimedia Programming Foundation Session:1 Tahun:2009 Versi:1/0

2. Bina Nusantara Learning Outcomes In the end of this session, students must be able to: –recognize Java technology –understand the concept of Graphics User Interfaces (GUI) –recognize the components and user actions of GUI –recognize Look And Feel (LAF) in Java

3. Bina Nusantara Course Outlines Java Technology Graphics User Interface (GUI) User Interface Components User Actions (Interactions) Java GUI User Interface Manager (Look And Feel)

4. Bina Nusantara Java Technology Both a programming language and a platform Java programming language is a high-level language that can be characterized by all of the following buzzwords: –Simple –Object Oriented –Distributed –Interpreted –Robust –Secure –Architecture Neutral –Portable –High performance –Multithreaded –Dynamic

5. Java Technology Software development process: JVM (multiple platforms) Bina Nusantara

6. Java Technology Platform is the hardware or software environment in which a program runs. The Java platform has two components: –The Java Virtual Machine –The Java Application Programming Interface (API) API: Core functionality of the Java. –Classes: basic objects, networking and security, XML generation and database access, and more Bina Nusantara

7. Graphics User Interface (GUI) Pronounced /’ ɡ u:i/  “goo-ey” Human-computer interface (way for humans to interact with computers) Uses windows, icons and menus Can be manipulated by a mouse Often to a limited extent by a keyboard Three Concepts: –Graphics (text, image, geometric figures) –User Interface Components –User Actions (Interactions) Bina Nusantara

8. User Interface Components Bina Nusantara Frame (Top-level Window) Title Bar Menu Bar Menu Items Button Combo Box Text Field Image Icon Check Box Radio Button Tab Pane Mnemonics Vertical Scroll Bar Horizontal Scroll Bar

9. User Actions (Interactions) Key Mouse Button Menu Bina Nusantara Actions: Press Key Click Mouse Click Button Select Menu Events: Key Event Mouse Event Action Event PROGRAM causes notify Listen Handle User respond action User click showclick show
