How can AlbumList access mImgDB and mNetAccess?
One solution could be to register the controller itself in qml and

sth like this in qml:

AlbumList {
imgDB: controller.imgDB
netAccess: controller.netAccess
}

but it's redundant.
This doesn't look like a bad approach to me (although passing the
controller itself might be cleaner).
An alternative might be to make Controller a singleton, that way your
AlbumList class could access it from the C++ without needing to be
explicitly passed a handle to it.
But whether you can do that depends on the how Controller is used.
Thanks a lot.
I'm not familiar with singletons, but this sounds promising.
I found this simple example:

I hope this also works for Q_OBJECT s.
Maybe I should rather make netAccess and imgDB itself singletons?
