each TableItem has a getChecked() method to read its checked state. The
SelectionEvent fired by the Table will inform you about changes. The
detail field is set to SWT.CHECK in this case.
You can find more information in the JavaDoc.
Hope that helps,
Rüdiger

as long as you don't add a SelectionListener there are not extra
rountrips. The state is kept in the TableItem in any case. Thus
iterating over all items and asking getChecked() will give you the
current checked state.
Cheers,
Rüdiger
