Hi Pierre-Yves,

TreeView and Calendar where originally released as separate components to the marketplace, and later integrated into Qt Quick (Controls). I don’t know which exact qt.io <http://qt.io/> page you are looking at, but I suspect that what you found as not licensed under the LGPL is the former, while the code in qtdeclarative is of course the latter.

https://bugreports.qt.io/browse/QTBUG-96585 is about integrating those components into Qt Quick, and can indeed be closed.
