Problems with QtQuick wizard generated project

[anda_skoa]

Lets try with a very simple example

main.cpp

#include <QtQml>
 
int main(int argc, char **argv)
{
    QCoreApplication app(argc, argv);
 
    qmlRegisterType<QTimer>("APP_CHILD", 1, 0, "AppChild");
 
    QQmlEngine engine;
 
    QQmlComponent component(&engine);
    component.setData("import APP_CHILD 1.0\n\nAppChild { }", QUrl());
    qDebug() << "created object=" << component.create();
 
    return 0;
}

#include <QtQml>

int main(int argc, char **argv)
{
    QCoreApplication app(argc, argv);
    
    qmlRegisterType<QTimer>("APP_CHILD", 1, 0, "AppChild");
    
    QQmlEngine engine;
    
    QQmlComponent component(&engine);
    component.setData("import APP_CHILD 1.0\n\nAppChild { }", QUrl());
    qDebug() << "created object=" << component.create();

    return 0;
}

To copy to clipboard, switch view to plain text mode 

appchildtest.pro

TEMPLATE = app
TARGET = appchildtest
INCLUDEPATH += .
 
# Input
SOURCES += main.cpp
 
QT += qml

TEMPLATE = app
TARGET = appchildtest
INCLUDEPATH += .

# Input
SOURCES += main.cpp

QT += qml

To copy to clipboard, switch view to plain text mode 

Executing that should give you an output like this:

created object= QTimer(0xc2b250)

Once you've veryfied that, add you class and register it instead of QTimer.

Your example works perfectly, this makes me think there's some problem in the way I've attached the main.qml file in my project. But that was done automatically by the Qt Quick wizard for projects creation. This thing is making me crazy!!!

Have you tried running the program from a terminal/shell?

Just to make sure you are actually running the program, not just "running" the QML file.
