      Hi and welcome to devnet,

      It's behaving as expected. a.exec() starts the event loop, but since you are doing nothing, it will run forever until you kill the application.

        Thanks for the response!

        Why is it not displaying the below line of code?

        cout << "tesT";

        Thanks for your help,

        Duncan

          HI and welcome to devnet,

          cout is a buffered stream; it doesn't print the stream until you don't flush (endl flushes)

          try with cout << "Test" << endl;

          Once your problem is solved don't forget to:
