[news.eclipse.platform.swt] dialog window which button with time and pre

[Martin Jedlička <jedlicka@xxxxxxx>]

How can I create dialog window (or message window/box) which include 
button with decrement time??

I want to create dialog window with button. This button will show time 
from 5 second to 0 second. If time will be 0 second this button will 
press (simulate click button).

How?

Thanks.

Martin
