Is there a way to add items past the initial visible screen using
FormLayout? More specifically, I have a Composite with a verticle scroll
bar which I'm adding controls to using FormData with the "top" attribute
set to a FormAttachment to the previously displayed Control. However, the
scrollbar is only scrolling to the last item that fits on the size of the
screen initially displayed, and no other items seem to be put on the
composite. I tried setting the bounds of the Composite to something
larger than its size, but that still didn't work. Any suggestions?

The scrollbars in a Composite need to be managed by the application. =
FormLayout (or any other SWT layout) does not manage scrollbars. See =
org.eclipse.swt.custom.ScrolledComposite.

See also this SWT snippet:
