[Interest] QQmlApplicationEngine::warnings is not emitted

[Alexander Dyagilev]

Hello,

Why this can happen?

I'm getting empty root objects, errors in Application Output tab in Qt 
Creator and empty qmlWarnings variable.

m_engine.reset(newQQmlApplicationEngine);

QList<QQmlError>qmlWarnings;

qtconnect(m_engine.data(),&QQmlApplicationEngine::warnings,

[&qmlWarnings](constQList<QQmlError>&warnings)

{

qmlWarnings.append(warnings);

});

m_engine->load(qmlUrl);

if(m_engine->rootObjects().isEmpty())

{

m_initFailed.first=true;

m_errorDesc=QObject::tr("QMLloadfailure.");

}
