Restart aplication with some proprieties from the previous

[SamuelNLP]

I have a Qt application in which I want to put a restart button, but when it restarts I want it to automatically reconnect with my bluetooth device. here's my code:


void gui::restartapp()
{
int index_combo;

index_combo= ui->devices_infile->currentIndex();

QProcess::startDetached(QApplication::applicationF ilePath());
exit(12);

char *dest;
dest = addr_infile[index_combo];

sock = linkup_directmain(dest, sock);

if (sock != 0 && sock >0)
{
ui->console_1->setText("Connected to:");
ui->console_2->setText(name_infile[index_combo]);
}

else if (sock == -1)
{
ui->console_1->setText("Error connecting");
ui->console_2->setText("Check device status");
}
}

but it only restarts. any idea?

Thank you in advance.

Having no idea what the rest of your code does, it's kind of impossible to tell you what is wrong.

However, consider a pattern:

(operating)
- Write current state to a file

(starting)
- If a state file exists, read it.
- If the state inside of that file indicates to do something, do it.

I got it to work with `QSettings`. I'll publish it later in case someone else needs it. It can work with a file as well as you say.
