    //Code as an "Empty qt project"

    #include <iostream>
    using namespace std;

    void main()
    {
    cout << "Hello World " << endl;

    }

        I get no action. Only a message for every code line. The one I mentioned before.

          That's normal, the pro file is not the place to write c++ code. Create a new default widget project and you'll see

            Yes, I suppose that the code has to be written in the .cpp file and that for each project, a .pro and a .cpp file are automatically created. Aren't they?

            My .cpp file is not created.

                Hi dear SGaist :*

                astello_, Dear friend follow me in below steps:

                • Run Qt Creator
                • Click on New project
                • Select Qt Widgets Application and press Choose
                • Type a name for ur project and click on Next
                • In this window select compiler and press Next **Note that if you use from MSVC you should download version of Qt Creator which is compatible with Visual Studio.
                • Here just click on Next and after it Finish
                • Look left side of Qt Creator and open main.cpp from Source folder
                • Add my new code line in main.cpp then Run it
                  @
                  #include "mainwindow.h"
                  #include <QApplication>

                #include <iostream> // Add This Line
                using namespace std; // Add This Line

                int main(int argc, char *argv[])
                {
                QApplication a(argc, argv);
                MainWindow w;

                cout<<"Hello World :)"<<endl; // Add this line

                w.show();
                return a.exec&#40;&#41;;
                

                }
                @

                • After run "Hellow World :)" will print on Application output in bottom of Qt Creator
                • say ur experience after u doing it

                  @ a.jafarabadi Qt Creator can use MSVC or MinGW indifferently. It's Qt's version which must match.

                    dear SGaist yes, it's true. we all now always the least version is better :) and the least version have some sub-version which you better now. in that post i want to say if my friend using from visual studio compiler it's good that download Visual studio sub-version of qt

                      Thank you for your help.

                      You two are right. If I follow these steps I can do it, but what I need is to open an Empty Qt project.

                      Here, when I write my code and compile it, it is impossible to run in terminal.

                      I get the message: "Press return to close this window".

                      I feel that we are close to the solution but I can't find it.

                      What do you think?

                      Thank you again.

                        What do you mean by run in terminal ?

                        In any case, running an application outside Qt Creator requires the same step as you would have to do in order to deploy it on another computer.

                                  Yes.

                                  New File/project -> Other project -> Empty Qt project. That's what I need.

                                    Then it's not a console application. You asked for an empty project so you have to write everything yourself. What did you write for this project ?
