console always popup in release mode

[gerardpuducul]

HI all,

I had an application which can be launch in GUI mode and in Console Mode :

#include <QtGui/QApplication>
#include "flashloader.h"
 
 
#include "QMap"
#include <iostream>
#include "QMessageBox"
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
 
    QMessageBox msgBox;
    msgBox.setText("number of argument : " + QString::number(argc));
    msgBox.exec();
 
    QStringList List_args = QApplication::arguments();
 
    int iCount;
    iCount = argc;
    QMap<QString, QString>  map_args;
 
    FlashLoader w;
 
    if (argc == 1)
    {
        w.show();
        return a.exec();
    }
    else
    {
        int i;
        for (i=1; i < argc ; i++)
        {
            std::cout << "MainAppCore argv[" << i <<  "] : " << List_args.at(i).toStdString() << "\n";
        }
        return 0;
    }
}

#include <QtGui/QApplication>
#include "flashloader.h"


#include "QMap"
#include <iostream>
#include "QMessageBox"

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

    QMessageBox msgBox;
    msgBox.setText("number of argument : " + QString::number(argc));
    msgBox.exec();

    QStringList List_args = QApplication::arguments();

    int iCount;
    iCount = argc;
    QMap<QString, QString>  map_args;

    FlashLoader w;

    if (argc == 1)
    {
        w.show();
        return a.exec();
    }
    else
    {
        int i;
        for (i=1; i < argc ; i++)
        {
            std::cout << "MainAppCore argv[" << i <<  "] : " << List_args.at(i).toStdString() << "\n";
        }
        return 0;
    }
}

To copy to clipboard, switch view to plain text mode 

In my pro files, I have

CONFIG += console

CONFIG += console

To copy to clipboard, switch view to plain text mode 

(necessary to have console working)

In debug mode all is working well. If I launch the application with no argument I have only the GUI present. If I launch the application with argument I have only the console present. The problem is when I launch the application in release mode ,the console always appears. How can I fix that?

Thanks

Hi,

I think that argc will be 1 if there are no arguments because the application name is inserted as the first argument, so you have to check if argc is bigger than 1.

Hi,

I believe the problems was there. This is why I display a MessageBox. But even in Debug or in Release argc==1 (and I display it in message box).

This code is running well if I launch from QTCreator in debug and Release mode.

But I launch it directly from the exe I have always the console present

Any other Idea?

Because QTCreator put some args to application ? Line 25 detects if You have some args (argc > 1) or not. If You want to run application with exactly one argument line 25 should be :

if(argc == 2)

if(argc == 2)

To copy to clipboard, switch view to plain text mode 

BTW it is better use of QCoreApplication::arguments.

Ok please don't focus on number of arg !!!
If I use this code :

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
 
    FlashLoader w;
 
        w.show();
        return a.exec();
 
}

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

    FlashLoader w;

        w.show();
        return a.exec();

}

To copy to clipboard, switch view to plain text mode 

and in my pro file

CONFIG += console

CONFIG += console

To copy to clipboard, switch view to plain text mode 

If I run in Debug or Release mode through QTcreator I have no console open

If I run directly the exe, I have always console present

Hi,

You can use "--console" as argument to your application. In "main.cpp" you have to search if there is "--console" in some of the arguments. If you find it you can open your application as console and if you don't find it open as GUI.
