Introduction

• Motivation
• The Presentation Unit will be implemented in Java
  and require a Graphical User Interface
• JFC/Swing provides for GUIs in Java
• My prior exposure to Swing was limited
• Objectives
• Learn the foundations of GUI programming using
  Swing
• Practice these skills by working on a learning
  project
• Devote no more than one week to the project
• Focus
• Learn the Swing concepts and components most
  relevant in implementing the Presentation Unit

Swing Foundations

• Swing Components
• Top-level container JFrame
• All other components descend from JComponent
• JPanel, JButton, JMenu, JLabel, etc.
• Event Management
• Events occur whenever user clicks mouse, etc.
• Objects register to be notified of events
• Event-handling code runs in a single
  event-dispatch thread
• Swing is part of the Java Foundation Classes
• Also includes look-and-feel, accessibility,
  Java2D, etc.

Learning Project

• Overview
• Have separate sorting routines, in logically
  separate parts of the interface
• Choice of sorting essentially arbitrary
  represents a computational process that does some
  work
• Represent sorting process visually
• Run routines to obtain timing data
• Visualize this data in a chart
• Other Features
• Be able to save data to a file
• Be able to load data to visualize from a file

Learning Project (cont.)

• Relevant Components
• Top-level frame, tabbed panels, buttons, etc.
• Menu bar, standard file open/save dialogs
• Text display area for messages
• Relevant Concepts Tools
• Component layout via layout managers
• Basics of custom component drawing
• Charting using Chart2D

7
Conclusions

• Java GUI Implementation
• The GUI is a fundamental part of the performance
  tools Presentation Unit
• JFC/Swing provides for fully-functional GUIs
• Learning Project Completion
• All major functionality implemented as planned
• Program is not fancy, but
• Future Work
• Start designing and implementing the Statistics
  and Calltree visualizations
