How to kill and rerun the main process in qt?
Comment

To kill and rerun the main process in a Qt application, you can use the QProcess
class to start a new instance of the application and then terminate the current process. Here's an example:
cpp#include <QCoreApplication>
#include <QProcess>
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
// Terminate and rerun the process
auto process = new QProcess();
process->start(QCoreApplication::applicationFilePath());
QCoreApplication::quit();
return a.exec();
}
In this example, the main function of your Qt application creates a new instance of QProcess
and starts it with the QCoreApplication::applicationFilePath()
method, which returns the file path of the current application. This will start a new instance of your application.
After starting the new process, the QCoreApplication::quit()
function is called to terminate the current process.
Make sure to include the necessary headers (QCoreApplication
and QProcess
) and adjust the code as per your application's requirements.
