Question

Can somebody please show me an example?

Answer 1

To restart application, try:

#include <QApplication> #include <QProcess>  ...  // restart: qApp->quit(); QProcess::startDetached(qApp->arguments()[0], qApp->arguments()); 

Answer 2

I'm taking the other answers solutions, but better. No need for pointers, but there is a need for a ; after the while statement of a do { ... } while( ... ); construct.

int main(int argc, char *argv[]) {     const int RESTART_CODE = 1000;      do     {         QApplication app(argc, argv);         MainWindow main_window(app);     } while( app.exec() == RESTART_CODE);      return return_from_event_loop_code; }
