The Standard Widget Toolkit (SWT) is a Java class library that allows you to create native user interfaces. It's designed to provide efficient, portable access to the underlying facilities of the operating system on which it's implemented. SWT uses native widgets wherever possible, giving an SWT program a native look and feel and a high level of integration with the desktop. In addition, SWT includes a rich set of controls such as tree, table, and tab folder. This article introduces SWT by describing some of the basic concepts and classes. Hello World: A Simple SWT Program The easiest way to learn SWT is to study a simple example. The following code shows a complete SWT program that creates and displays a new window on the desktop with "Hello World" in the title bar. Figure 1 shows the result of running this program on Windows XP. --> 1 import org.eclipse.swt.*; 2 i... (more)

The Vision for Eclipse: An Interview with Mike Milinkovich

Mike Milinkovich, executive director of the Eclipse Foundation, has been kind enough to answer some questions for Enterprise Open Source Magazine. Rather than rattle off the usual ones about the name, about why Swing wasn't used, or how much influence IBM still has, Mike has fielded questions on some more current and topical subjects, as well as given us his insights onto the future. Thanks for taking the time to talk to us Mike. View Milinkovich on SYS-CON.TV EOSM: The Eclipse Foundation recently joined the Java Community Process. Can you tell us how this is going and what you ex... (more)

JDJ Editorial: IT Olympics

There are a number of esteemed contests for the greatest and fastest software developers among us - events where we can pit our coding prowess against fellow brainiacs and like-minded techies. I think it's high time we had an alternative set of awards, suited not to aspiring budding Turing machine engineers, but rooted more in the humdrum real, rather than artificial academic, world. The Herring Rouge Chase To win this award you have to think that when a piece of code you authored isn't working correctly that the problem isn't your error but instead lies elsewhere in the broken ...

Among geneticists there is an ongoing argument about which species is superior: humans or bacteria. Both are the end product of millions of years of evolutionary refinement; they just took separate routes on the road to survival. Humans represent the pinnacle of animal development, possessing feature upon feature such as communication and the ability to alter the environment to suit their needs, while bacteria took the opposite tack and remained single-celled organisms that adapt to fit their environment. Large animal species tend to be very vulnerable to environmental change as ... (more)

Square Data and Round Holes

My first programming job was done using Report Generator Language (RPG) on the IBM System 36. The hardware was green screen, the tape decks reel-to-reel, and the printers large and noisy. The language itself was very data-centric with each program declaring formatted Input or Output data structures that were read or written to. Each structure mapped to a file, a screen buffer, or a printer spool. In spite of all this we did get the job done, although our biggest problem was the business changing requirements on us that necessitated altering the data structures. Because they were ... (more)
