[Interest] Conflicts with Qt Qml Engine? - Are there any DaVinci Resolve team members around?

[Nuno Santos]

Fabian,

Thanks for your swift reply.

That was indeed the problem. By setting the import path to:

engine()->setImportPathList(QStringList() << "qrc:/qt/qml" << "qrc:/qt-project.org/imports”);

Fixed the problem. 

Do you see any other problem using this simple approach?

Thank you!

Best regards,

Nuno
