Reload environment on runtime

PabloArg

Hi,

I would like to know if possible to reload the environment on runtime. Imagine the following situation. The application start and this add a path to the system, so How Do I reload the environment again that my application can see the new path?

Thanks for your help

Apparently, yes with systemEnvironment
You might want to chekc this out.

I saw that option but looks only apply if you are running some Qprocess later. But in my case I am running an external app using ShellExecuteEx of windows. I don't know if I can use it, I tried before without success.

QProcess process;
QProcessEnvironment env = QProcessEnvironment::systemEnvironment();
env.insert("TMPDIR", "C:\MyApp\temp"); // Add an environment variable
env.insert("PATH", env.value("Path") + ";C:\Bin");
process.setProcessEnvironment(env);
process.start("myapp");

I have a button that contain the following code:
QStringList env(QProcess::systemEnvironment());
qDebug() << env ;

With my app still running I added a new path from System Property ->environment variable.

So I click in the button but my new path doesn't show up, any ideas?

Nope. Unfortunately the only possibility I saw.
