In very basic steps I would suggest: 1) Build a very simple "Hello World" Qt app. There are some examples of how to do this in the Qt tutorials and samples. Don't worry about the console yet -- just get it working as a regular Qt gui app. 2) Add to it a button that every time you click it updates a label or line-edit with something simple like "1", "2", ... 3) Now add CONFIG += console to your .pro file, and to the code that responds to the button click and updates the label in the gui add a write to cout. Now whenever you click your button not only should your gui update, but your message to cout should appear in the console window. This will illustrate how normal Qt gui apps are event driven (In this case the events are button clicks.), and how you can write to the console. At a fancier level, it wouldn't surprise me if the app in the video you linked to has one non-gui thread running the optimization, while the gui thread is responsible for displaying the travelling-salesman paths. I believe that it would work to have the non-gui thread write to the console, as I imagine is happening in the video (but as I mentioned in my previous post that I'm a bit foggy on this point). > once again, thanks a lot! > > Best regards > > Daniel Happy Travelling-Salesman Hacking!
