Out of curiosity decided to check the state of the issue in Qt:

Widgets and Layouts

Qt 4.4 introduced support for geometry and layout-aware items through QGraphicsWidget. This special base item is similar to QWidget, but unlike QWidget, it doesn't inherit from QPaintDevice; rather from QGraphicsItem instead. This allows you to write complete widgets with events, signals & slots, size hints and policies, and you can also manage your widgets geometries in layouts through QGraphicsLinearLayout and QGraphicsGridLayout.
QGraphicsWidget

Building on top of QGraphicsItem's capabilities and lean footprint, QGraphicsWidget provides the best of both worlds: extra functionality from QWidget, such as the style, font, palette, layout direction, and its geometry, and resolution independence and transformation support from QGraphicsItem. 
".

So, so I understand correctly that Qt supports resolution independence ?
