copied!<p>There are no corresponding interface in Eclipse to access any current model dialog. The best approximation is <code>Display.getActiveShell()</code>, which will return the shell that hosts the active dialog if one exists.</p> <p>[Dialogs are implemented by having their own event loop, so it can be rather difficult to run your own code...]</p> <p><em><strong>EDIT</strong></em>: Based on your comment below, here is a small snippet I use constantly to test for the presence of specific preference pages. I guess this can be used used as the starting point for your own test...
