in my mainwindow.cpp, inside the constructor, I started a qprocess so the process(.exe) runs when I open the qt application.
Now I want to kill/close the qprocess when I close the qt application. How can I do it?
See the documentation for QProcess::terminate
and QProcess::kill
. They each have slightly different behavior. Use terminate
to give the process a chance to shut down gracefully. Use kill
to kill it more forcefully. In the case of terminate
, you probably want to wait until the child process has finished (eg QProcess::waitForFinished
) before exiting the parent process.
