This package contains "Microsoft Office XP" and "Microsoft Office 2003" Look and Feels for Java Swing applications. These Look and Feels require a JRE running on Windows XP.
Here's what's new in 1.0.3:
1. Toolbar buttons and toolbar toggle buttons now can have both text and an icon. Before I was just lazy and they only supported one or the other, but not both.
2. The Office 2003 Look and Feel now implements the slight gradient for its menu bar and toolbar (it's slightly darker blue on the left side than on the right). If for some reason you really don't want this gradient, you can turn it off by adding the following line of code after setting the look and feel:
3. Fixed a focus bug in the combo box UI's that only affected 1.5 JRE's (not 1.4.x).
