[news.eclipse.platform.swt] Dispose Code - Need Everywhere, what needs t

[Soni <soni29@xxxxxxxxxxx>]

hi,
i had a question regarding the following lines of code:

        while (!shell.isDisposed ())
        {
            if (!display.readAndDispatch ())
            {
            display.sleep ();
            }
        }
display.dispose ();

does this code need to be everywhere, or just in one place?  if i have 3 
shells, do i need it in all of them?  what if i have my main in a class 
that does not include a shell, maybe makes an object of another class that 
will be the shell, does it have to be in both or just the one with main?

Also with dispose, do i need to dispose of everything?  can't i just 
dispose of the Display and shouldn't that in turn dipose everything else, 
if i have 20 gui components in a shell do i have to remove all of the 
myself, what about variables such as Integer or File?

Thank you.
