[Interest] Preferred way to create custom look-and-feel GUI

[Xavier Bigand]

If you want something modern you should use QML. Maybe with QtQuickControls
2.0 to get controls, because QtQuick itself provides only primitives,
Rectangle, Image, MouseArea,... but no buttons,...

QML is made to be easy to customize instead of Widgets, you will also
capable to do nice animations.

I am using QML professionally for a software written in C++, like you we
have a 3D view that it derived from a QQuickItem. It works nice but there
is few things to know. If your 3D engine isn't threaded you have to disable
threading of QML engine and it is better to do your rendering in the
onBeforeRendering.
