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.

Joe Winchester, Desktop Java Editor for Java Developer's Journal, asked Steve Northover (SWT Team Lead) recently whe... (more)

Devils, Demos, Details, and Demons

When a product a colleague worked on recently shipped its first generally available release, the event was accompanied by a marketing fanfare of podcasts, press releases, and conference trips to beautiful cities with boxes of presentation materials, branded lapel pins, and flashing fridge magnets. My colleague gave a hugely successful presentation to customers and was rather taken aback afterwards when she was approached by a member of her company's marking team who asked why it looked as though the development team hadn't done that much to the product since the last presentation...

Dialog Boxes, Habituation, and Single Threaded Thought

In Jef Raskin's excellent book, The Humane User Interface, he discusses how the human brain is able to perform many tasks simultaneously while only having the ability to focus on one conscious thought at a time. Being able to process information and analyze it intelligently is crucial to our ability to solve problems, but once we have learned how to deal with a particular situation, just as vital is our ability to remember and recall the response without thinking. This allows us to drive a car while thinking about what we're going to have for dinner that evening. If, on said jour... (more)
