Anyone know what the difference is between
addListener(SWT.Selection, ...) and
addSelectionListener(...)?
I always assumed these were equivalent, but I just discovered that when
embedding a button in a table the first form fires but the second doesn't.
So clearly there's a difference.
Thanks for any insights,
Doug

This article says that SelectionListener() is implemented in terms of
the primitive SWT.Selection event -- which is as you'd expect.
So given that I suppose this means there's a bug in this translation
when embedding a button in a table because only the untyped
SWT.Selection event fires and the typed form does nothing.
