Well, since I started developing in Qt, I've been told that using nested event loops is bad parallelization. A good way to fix the WallpaperInterface issue (I understand it's an example, but still applies) is that instead of calling completeInitialization() (wallpaperinterface.cpp:147) we should be connect to a signal that notifies us about the background readiness (i.e. statusChanged) and then react to the initialization by connecting the object into the graphical elements, but forcing the end of the initialization is, of course, not parallelizable. - Aleix ----------------------------------------------------------- This is an automatically generated e-mail.
