Installation of Qt Creator (Any version)

[SGaist]

What does c++ code do in your pro file ?

[astello_]

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

[SGaist]

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

[astello_]

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.

[SGaist]

Did you create a new Qt Widget Application like a suggested ?

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();

}
@

• 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.
