Create a script that waits till the current process finished, then start a new one.
Run the script when you close your program

Resources allowed not free by this method!!

No, you have to take care of your resources and memory allocations yourself. There's no magic "release all my memory and allocations for me" as it doesn't know what is in use.

Hi;
I have an application that is based on plugins, after several uses, I just do not unload this plugin (QPluginLoader:: unload ()) which remains blocked.

Whenever you want to restart the application just call exit(RESTART_CODE) to exit the event loop with RESTART_CODE.

Hi all,

To repeat the loop I would rather call:

qApp->exit(RESTART_CODE);

qApp->exit(RESTART_CODE);

To copy to clipboard, switch view to plain text mode 

Or indifferently:

QApplication::instance()->exit(RESTART_CODE);

QApplication::instance()->exit(RESTART_CODE);

To copy to clipboard, switch view to plain text mode 

Otherwise the program appears to be exited immediately.

Cheers,

Alexandre

You might want to reformulate your question, currently it is very generic. At this moment I'd say that the easiest way to restart an application is to close it and start it up again the same way it was started originally.

Unless you are in PySide/PyQt.
