Hello World
The famous example... doesn't look much different, but notice the tiny Java cup as a sign that this is Swing.
Address Book
The address book application from the SWT examples. The application's default size is too small if it starts up and you need to explicitly switch off radio buttons but the application really works.
File Viewer
Another example application: This starts up nicely (I've stubbed the file icons because I didn't find an easy way to get them with pure Java) but you can't open the tree view — threading issue.
Layout Example
This SWT example application still has layout issues (it dynamically adds and removes widgets and I don't revalidate the layout in those cases) but you can already play around with the fill layout. The other tabs use tables with table editors and editable comboboxes which aren't working yet. The tiny embedded editor originally uses a styled text editor but it seems that a normal editor also does the trick.
