Collect user input using qDebug

Question

I have been wondering if it is possible to collect user input using the qDebug() statement in Qt C++.

I tried do it like in the std C++ code like:

qDebug() >> myvar;

but it didn't work.

How can I read from stdin using Qt?

Answer 1

qDebug is used to make output to stderr. If you want to read from stdin using Qt, you should use QTextStream:

#include <stdio.h>

QTextStream in(stdin);

QString line;
in >> line;
