No, I was referring to the debug output. IDEs tend to show the debug output. If you're not using any IDE, on Windows you will have to add
CONFIG += console
in the .pro file, regenerate makefile and rebuild the application. An external console is launched together with the application from which you can see the debug output. Alternatively, you can use such utilities as DebugView to monitor the debug output.
