Starting with Qt4 and QtQuick 1 we built nearly the entire GUI of our software IPO.Log with QML.
We started with QDeclarativeItems and moved to QQuickItems while migrating to Qt5.
Our software uses highly complex data models, which have to be visualized with QML.
This presentation shows how multiple data-models can be combined to achieve this goal
and which issues appeared in the context of moving to QtQuick 2.
