Maybe not implement React, but Qt would benefit from using something like Facebook’s Flux architecture, where state flows down from parent objects to children.

Maybe not implement React, but Qt would benefit from using something like Facebook’s Flux architecture, where state flows down from parent objects to children. With Qt Widgets, it is annoying to create models (QAbstractItemModel), they are more difficult to implement than what it should and prone to errors. I haven’t done much QML beyond simple sample apps, but it seemed you still have to create Qt models for a lot of use cases.
