Restart app does not work

[guidupas]

Hello!

I am trying to restart my app using the code:

QStringList args = QApplication::arguments();
args.removeFirst();
QProcess::startDetached(QApplication::applicationFilePath(), args);
QCoreApplication::quit();

QStringList args = QApplication::arguments();
args.removeFirst();
QProcess::startDetached(QApplication::applicationFilePath(), args);
QCoreApplication::quit();

To copy to clipboard, switch view to plain text mode 

or

QProcess::startDetached(qApp->arguments()[0], qApp->arguments());
qApp->quit();

QProcess::startDetached(qApp->arguments()[0], qApp->arguments());
qApp->quit();

To copy to clipboard, switch view to plain text mode 

It works fine when I run it in Qt, but when I build it, generate the .pkg and install it does not restart and when I reopen the app it gives a message that the app was finished during windows reopen.

I am using OSX 10.9

Thanks very much.

What platform? Have you read the platform specific parts of the docs for arguments() and startDetached()?
Does startDetached() return true or false?
Is applicationFilePath() returning what you expect?
Is the first element of arguments() the program name you expect?
