That's why I wrote "[uses] under the hood" and not "inherits from" ;)
Maybe my "used as base" wording was a bit misleading here: I meant that the QtGui library acts as a "base" (basis? Sorry, not a
native English speaker here ;)) for both QWidget and QtQuick applications to interact with the underlying windowing system.
So whenever a QWidget figures out that it is a "top-level" widget it request a "native window" - by "using" a QWindow (in Qt 4.x and
earlier that Window Manager interaction was probably all coded into the QWidget (support) classes directly).
And I also wrote that a QWindow fits better into the "QtQuick world", since there it is indeed a base class (now in the
"inheritance" meaning ;)) for QQuickView etc. - for the QWidget world you need a "wrapper class:, said QWindowContainer.
Also refer to Laszo's reply :)
