jafarabadi.qt

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.

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.

SGaist

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.

astello_

Run in terminal = Projects (on the left side Menu) -> Run -> Run in terminal marked

SGaist

What project did you create ?

astello_

Empty Qt project

SGaist

Do you mean a console application ?

astello_

Yes.

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

SGaist

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 ?

astello_

#include <iostream>

using namespace std;

int main()
{
cout << "Hello" << endl;

}

SGaist

In what file did you write that ?

astello_

main.cpp

JKSH

Hi,

If you want a console application, you need to create a console application project, not an empty project.

File -> New File or Project... -> Applications -> Qt Console Application

After that, you can remove QCoreApplication from main.cpp if you don't want to use Qt classes.

IT WORKS!! Not as I expected in the beginning, but it is useful.

Thank you very much.

:)

if you want develop using native c++ it's better to use from an c++ IDE which is simplest from Qt Creator...
We download, install and use from Qt because of it's useful libraries...
i hope you can find best answer :)
