QtCreator std :: cout和输出窗格

Question

When I run console applications in QtCreator the output (and input - std::cout, std::cin) is done via xterm (my OS is debian). How can I make output to be shown in the QtCreator's output pane not in the xterm window?

Answer 1

From the Qt Creator website:

Application Output

The Application Output pane displays the status of a program when it is executed, and the debug output.

It does not look like the Application Output window is what you think it is.

Answer 2

You should use the QDebug() function for this. It's usage is pretty much the same as std::cout. Look at the example below:

float coordinate = 3.41;
qDebug() << "Custom coordinate type:" << coordinate;

This will output, in your QtCreator's output pane:

Custom coordinate type: 3.41

Don't forget to include this statement, in your includes block:

#include <QDebug>
