Process started with QProcess doesn't exit if we close the main application

[adnan]

Suppose i start a process in terminal in Linux, if the terminal is closed the child process started in terminal also exits. But if i start a process (say) p1 using QProcess inside a GUI application, and then close the gui application, process p1 still keeps running, as if it is a daemon, even if i don't start the process using QProcess::startDetached().

You may try this:

reimplement the protected function:
@protected:
void closeEvent(QCloseEvent *event);@

@void yourwidget::closeEvent(QCloseEvent *event)
{
anyprocess.close();
//from void QProcess::close () [virtual] - documentation
//Closes all communication with the process and kills it. After calling this function, QProcess
//will no longer emit readyRead(), and data can no longer be read or written

     event->accept();
