How to run ts_calibrate in qt application?

[MhM93]

Hi. I have friendly arm and I want to play ts_calibrate inside my qt app.I do not need the output of the program. I just run calibrate application from my app and after it finished, it closed and my app continue .
I wrote these code but it does not work:

QProcess *process=new QProcess;
//        QString file = QDir::homepath + "file.exe";
        QString file ="/usr/local/bin/ts_calibrate";
        process->start(file, QStringList() << "");
//        process.start(file);
        process->waitForFinished(-1);

could any one help me please?

@MhM93 If you say "it does not work" you should say what exactly does not work or what happens.
Does /usr/local/bin/ts_calibrate exist? Is it executable?
Why do you pass an empty string as parameter:

process->start(file, QStringList() << "");

?
Change it to:

process->start(file, QStringList());

Why do you wait for the process to finish?

when I clicked on my button to run these codes,my app hanging and nothing work on my device. I pressed ctrl+c to quit the app.
