Component.onCompleted with console.log not working, why please?

[Mlibu]

Hi there. I have a brand new empty Python Qt5 QML project application to which I have added a console.log. Why is my console.log not visible in Application Output? I have seen many examples where they use this technique for debugging and never have a problem.

import QtQuick 2.15
import QtQuick.Window 2.15

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    Component.onCompleted: {
        console.log("HEREHHERRHEHREHRHRE")
    }
}

I found the answer to this question. In the build environment I needed to add "QT_FORCE_STDERR_LOGGING=1" to the environment. I'm not sure why STDERR works, when the console.log should be STDOUT but anyway that solved my problem.

}

I tested it with qmlscene on Linux and log output is ok.

I have just noticed that it does come out on the command line but it is not displaying in Qt Creator in Application Output. Might you know why?

Thanks for the fast response, by the way.

Does qmlscene work on Windows? I am unable to use the design page in Qt Creator.

@Mlibu you check where qmake is located. qmlscene should there as well. I do not have Windows on my computer.

QT_FORCE_STDERR_LOGGING

Good for you. I do not have this setting on Linux and am able to see log output in qt creator. Your output is not error message. This setting is kind of odd.
