QConsoleListener

Small Qt library to handle console input asynchronously using signals and slots. Based on gjorquera’s snippet.

Usage

Add to project in *.pro file

include($$PWD/src/qconsolelistener.pri)

Include the header #include <QConsoleListener> and connect to the QConsoleListener::newLine signal. For example:

#include <QCoreApplication>
#include <QDebug>
#include <QConsoleListener>
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    // listen to console input
    QConsoleListener console;
    QObject::connect(&console, &QConsoleListener::newLine, 
    [&a](const QString &strNewLine) {
        qDebug() << "Echo :" << strNewLine;
        // quit
        if (strNewLine.compare("q", Qt::CaseInsensitive) == 0)
        {
            qDebug() << "Goodbye";
            a.quit();
        }
    });
    qDebug() << "Listening to console input:";
    return a.exec();
}
