Stupid question, but is this a console app?
I'm asking because this happens with console apps. It can happen with
any app, but console apps tend to have the problem most often. Here is
what I mean:
#include <QCoreApplication>
#include <QDebug>
#include <QTimer>
#include "consoleinput.h"
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
ConsoleInput console;
bool b = a.connect(&console, &ConsoleInput::quit, &a,
&QCoreApplication::quit);
qDebug() << "result of connect " << b;
QTimer::singleShot(0, &console, &ConsoleInput::run);
return a.exec();
}
If you do not use a QTimer to launch the console input method so it runs
from within the exec() loop, i.e. replace the QTimer line with
console.run();
Your connect call will return true but the signal will never trigger the
slot because execution is occurring outside of an event loop.
