How to use it with multiple qmlengines?

[scuhappy]

My QtQuick application contains more than one qmlengines, But I found that the Config is a singleton, It can not be loaded in other qmlengine if it has already has one.
Any ideas? Thank you!

Haven't thought much about this yet.

Will both qmlengines support dock widgets ?
And will you need to dock a dock widget from 1 engine into a window controlled to another ?

Hi iamsergio,
Thank you for your reply!
In my app, there may be more than one qmlengines , each engine contains a Window.
Currently we only allow one window is visible, and we will delete the previous window when new window is created. so we don't have requirement to dock a dockwidget from one Window to another Window.
I tried to modify the source code , just remove the code below in function void Config::setQmlEngine(QQmlEngine *qmlEngine). Is that OK ?
if (d->m_qmlEngine) { qWarning() << Q_FUNC_INFO << "Already has QML engine"; return; }

that might work, but it's best that I port away from the singleton
