QT Creator QProcess

Question

I want to run a fortran executable that is called when I click in push button in the interface that I created.

Although when I click in the button nothing happens. Here is the code:

QProcess *process = new QProcess(this);
QString program = QDir::currentPath() + "/PARROT/Console1.exe";
process->start(program);

The string is in that way because I want to be capable of changing the path to the main executable and the fortran executable.

What I'm doing wrong?

Have you stepped through these lines with a debugger to verify that `program` contains the expected path? — MrEricSir, Jun 10 '15 at 01:30
you can attach slot to readyReadStandardError() signal and see what's error is coming — Kunal, Jun 10 '15 at 02:17
Stderr probably doesn't report anything. But connect to the finished() and error() signals and check errorString() — Frank Osterfeld, Jun 10 '15 at 07:17
Try to use `QString program = QString("cmd /C %1%2").arg(QDir::currentPath()).arg("/PARROT/Console1.exe")` — t3ft3l--i, Jun 10 '15 at 07:46
Why is this tagged [tag:fortran]? For the question, it doesn't really matter where the executable comes from... — Alexander Vogt, Jun 10 '15 at 10:51

syntax - void QProcess::start(const QString & program, const QStringList & arguments, OpenMode mode = ReadWrite)

You need to pass the argumentlist as 2nd parameter,along with the process path as 1st parameter, needed to start the process.
