I got my first Eclipse plug-in working! I'm so excited! It works in Eclipse 3.1, Windows XP, and Java 1.5. I'm so proud of myself. It was a lot of fun to program. You might ask yourself, what is it? Well, it's a Thesaurus that accesses www.thesaurus.com and reformats the output to make all words clickable. It still needs more work like keyboard shortcuts, the ability to click on a word in the editors, and back/forward buttons.
SWT was a complete pleasure. It's an elegant design and far better than Swing (I could write a book about all of the bad design decisions in it). So now, I have one of my favorite tools in Eclipse as well. ROCK! My next project is the ability to give presentations in Eclipse. I'm thinking Groovy might be the perfect vehicle.
