Hello co-testers, hello Ketan Padegaonkar, it's time to keep my promise and show you the code for the SWT replacements. I simply pasted them into the mail. You can use it under the same license terms, as SWTBot itself. If want the code in a more suitable form (zipped eclipse project...), drop me a mail.
The first code is the core of this replacement - it is a static factory, that your application code can use to show dialogs. ===================== Code Listing NativeDialogFactory ====================================== /******************************************************************************* * Copyright (c) 2009 Jan Petranek. * All rights reserved.
