I've written my last Swing app... (SWT is *so* the business...) I've spent the last month getting to know SWT, and I've gotta say that I've written my last Swing app. After spending far too long messing with Swing MVC pattern and writing modeller code for my damn combo boxes, that's it. I've had it. I've come to the conclusion that I'm just not smart enough to grok Swing.
Personally, I've used both Swing and SWT. I've not found a decided edge with either in terms of ease of use. Personally, I kinda like having a more structured model behind my components in Swing.
