Hi, I created an app with Qt Creator and ArcGIS SDK For Qt before started using AppStudio. Then i created an app with AppStudio and i moved all my resources, qml pages on Qt Creator which was installed with AppStudio. My AppStudio app works perfectly after eliminated the differences from other main project . But I have a problem with c++ extensions. I have several qml types which was created with c++ like this link Defining QML Types from C++ | Qt QML 5.7 . But i cannot moved this types my new AppStudio project. Is that possible ? If it is anybody can show me any guidance or tutorial ?
