Not exactly. The problem is the asynchronous nature of fork()+exec() on Unix

Sorry, no. Just the name of the signal you proposed shows it's a bad idea.
Signals are always named after verbs in the past tense,

It turns out that I'm not even using that anymore.
In the situation that there's a problem, you end up waiting for timeout.
So:
connect(process,QOverload::of(::finished),
, ::quit);
)
, this
, ::controllerError);

This does not give an error, but is also wrong, I think:
connect(process, QOverload::of(::finished), ,
::quit);
QEventLoop::quit slot does not take any parameters
What's wrong with this? The signal can have more parameters than the
signal - this was
void waitForProcessFinished(QProcess *process, const QString , int
timeout) {
QTimer timer;
QEventLoop loop;
connect(, ::timeout, , ::quit);
connect(process, ::finished, , ::quit); //
can't resolve ::finished
if (timeout > 0 ) {
11 matches
