How to learn SWT

Today, I was looking for some good resources to learn SWT in a structured way. Here are the findings:

The book titled "SWT: The Standard Widget Toolkit" seems to be a great place to start. This is available for free online reading at http://safari.informit.com/0321256638. Once you skim through this book, you should see that the following understanding is essential to proceed to be an expert:

1. Fundamentals - Why we need? What is it? How is it different? What is the scope?
2. SWT Concepts - Overall architecture
3. SWT Widgets - Nuances to get working. Quick reading and a handy reference book /web access should do.
4. SWT Sample Applications - Keep them handy for a speedy start.

Once these are done, I plan to contribute into some good SWT forums and get advanced knowledge on bugs or known issues.
