The Desktop (Overview)
The desktop (overview) The desktop is the main screen area that you see after you turn on your computer and log on to Windows. Like the top of an actual desk, it serves as a surface for your work. When you open programs or folders, they appear on the desktop. You can also put things on the desktop, such as files and folders, and arrange them however you want. The desktop is sometimes defined more broadly to include the taskbar and Windows Sidebar. The taskbar sits at the bottom of your screen. It shows you which programs are running and allows you to switch between them. It also contains the Start button , which you can use to access programs, folders, and computer settings. On the side of the screen, Sidebar contains small programs called gadgets. The desktop, taskbar, and Sidebar Where did my desktop go? Because programs run on top of the desktop, the desktop itself is often partially or completely hidden. But it's still there, underneath everything. To see the whole desktop without closing any of your open programs or windows, click the Show Desktop button on the taskbar. The desktop is revealed. Click the icon again to restore all of your windows to the way they were. Desktop Training Session Handout Page 1 http://ict.maxwell.syr.edu/vista/ Working with desktop icons Icons are small pictures that represent files, folders, programs, and other items. When you first start Windows, you'll see at least one icon on your desktop: the Recycle Bin (more on that later). -
Programming Java for OS X
Programming Java for OS X hat’s so different about Java on a Mac? Pure Java applica- tions run on any operating system that supports Java. W Popular Java tools run on OS X. From the developer’s point of view, Java is Java, no matter where it runs. Users do not agree. To an OS X user, pure Java applications that ignore the feel and features of OS X are less desirable, meaning the customers will take their money elsewhere. Fewer sales translates into unhappy managers and all the awkwardness that follows. In this book, I show how to build GUIs that feel and behave like OS X users expect them to behave. I explain development tools and libraries found on the Mac. I explore bundling of Java applications for deployment on OS X. I also discuss interfacing Java with other languages commonly used on the Mac. This chapter is about the background and basics of Java develop- ment on OS X. I explain the history of Java development. I show you around Apple’s developer Web site. Finally, I go over the IDEs commonly used for Java development on the Mac. In This Chapter Reviewing Apple Java History Exploring the history of Apple embraced Java technologies long before the first version of Java on Apple computers OS X graced a blue and white Mac tower. Refugees from the old Installing developer tan Macs of the 1990s may vaguely remember using what was tools on OS X called the MRJ when their PC counterparts were busy using JVMs. Looking at the MRJ stands for Mac OS Runtime for Java. -

Based on an investigation of programming techniques such as drawing graphics and event driven program, example codes are provided in which GUI is implemented using the Abstract Window Toolkit (AWT). The marked advantage of Java comes from the inclusion of library routines for graphics and networking as its language specification, which enables ordinary scientific programmers to make interactive visualization a part of their simulation codes. Moreover, the Java programs are machine independent at the source level. Object oriented programming (OOP) methods used in Java programming will be useful for developing large scientific codes which includes number of modules with better maintenance ability. -
Spot-Tracking Lens: a Zoomable User Interface for Animated Bubble Charts
Spot-Tracking Lens: A Zoomable User Interface for Animated Bubble Charts Yueqi Hu, Tom Polk, Jing Yang ∗ Ye Zhao y Shixia Liu z University of North Carolina at Charlotte Kent State University Tshinghua University Figure 1: A screenshot of the spot-tracking lens. The lens is following Belarus in the year 1995. Egypt, Syria, and Tunisia are automatically labeled since they move faster than Belarus. Ukraine and Russia are tracked. They are visible even when they go out of the spotlight. The color coding of countries is the same as in Gapminder[1], in which countries from the same geographic region share the same color. The world map on the top right corner provides a legend of the colors. ABSTRACT thus see more details.

Tracker Helps You Mark the Steps but Does Not Limit Your Control Over Them
Tracker 6 Help Tracker is a free video analysis and modeling tool from Open Source Physics (OSP). Features include manual and automated object tracking with position, velocity and acceleration overlays and data, video filters, line profiles for analysis of spectra and interference patterns, and dynamic particle models for direct comparison with real-world videos. It is designed to be used in physics education but is also widely used in many other fields. To start using Tracker, see getting started. Getting Started When you first open Tracker it appears as shown below. Here's how to start analyzing a video: 1. Open a video or tracker file. 2. Identify the frames ("video clip") you wish to analyze. 3. Calibrate the video scale. 4. Set the reference frame origin and angle. 5. Track objects of interest with the mouse. 6. Plot and analyze the tracks. 7. Save your work in a tracker file. 8. Export track data to a spreadsheet. 9. Print, save or copy/paste images for reports. Note that the order of the buttons on the toolbar mirrors the steps used to analyze a video. For more information about Tracker's user interface, including user customization, see user interface. 1. Open a video or tracker file To open a local video, tracker tab (.trk), or tracker project (.trz) file, click the Open button or File|Open File menu item and select the file with the chooser, or drag and drop the file onto Tracker. You can also open still and animated image files (.jpg, .gif, .png), numbered sequences of image files, and images pasted from the clipboard. -

Abstract Window Toolkit Overview
In this chapter: • Components • Peers 1 • Layouts • Containers • And the Rest • Summary Abstract Window Toolkit Overview For years, programmers have had to go through the hassles of porting software from BSD-based UNIX to System V Release 4–based UNIX, from OpenWindows to Motif, from PC to UNIX to Macintosh (or some combination thereof), and between various other alternatives, too numerous to mention. Getting an applica- tion to work was only part of the problem; you also had to port it to all the plat- forms you supported, which often took more time than the development effort itself. In the UNIX world, standards like POSIX and X made it easier to move appli- cations between different UNIX platforms. But they only solved part of the prob- lem and didn’t provide any help with the PC world. Portability became even more important as the Internet grew. The goal was clear: wouldn’t it be great if you could just move applications between different operating environments without worr yingabout the software breaking because of a different operating system, win- dowing environment, or internal data representation? In the spring of 1995, Sun Microsystems announced Java, which claimed to solve this dilemma. What started out as a dancing penguin (or Star Trek communicator) named Duke on remote controls for interactive television has become a new paradigm for programming on the Internet. With Java, you can create a program on one platform and deliver the compilation output (byte-codes/class files) to ever yother supported environment without recompiling or worrying about the local windowing environment, word size, or byte order. -
