"This lesson is part of a series of lessons designed to teach you how to use the focus subsystem. This is also the first part of a two-part lesson to teach you how to use the Window focus and state features."
"The first lesson in the series was entitled Focus Traversal Policies in Java Version 1.4. The previous lesson was entitled Changing Focus Traversal Keys in Java V1.4."
"I became hooked on Java in April 1996. Since then, Java has progressed from V1.0 up to V1.4. Fortunately, during that period, few if any of the improvements included in new versions have been incompatible with code written for previous versions. Unfortunately, that history of upgrade success changed with the release of the new focus subsystem in V1.4. Several aspects of the new subsystem are incompatible with code written for previous versions."
"Furthermore, with V1.4, every different component within a focus traversal cycle can use a different set of traversal keys, and the set of keys being used for any component can be modified at runtime. (I will demonstrate this with the programs that I will discuss later in this lesson.)"
"The first lesson in the series was entitled Focus Traversal Policies in Java Version 1.4. The previous lesson was entitled Window Focus and State in Java, Part 1 of 2."
"The recently released JavaTM 2 SDK, Standard Edition Version 1.4 contains a large number of new features, including many changes and additions to the focus subsystem. This is the second lesson in a new miniseries that will teach you how to use the features of the new focus subsystem. The first lesson in the series was entitled Focus Traversal Policies in Java Version 1.4."
