[Qt-interest] OpenGL inside QT with accelaration

Yes i written my code until now in "pure" OpenGL,
And i use a QGLWidget.

Yes :)

But then i dont understand the way the documentation says it.
the docs says, using QPainter the OpenGL will use the HW accelaration
if it exists.
and otherwise falls back to using software.

!This is not a direct quote of the documentation!!

But that is true for openGL also isnt it?
Its not an attribute of QPainter?

So whats the difference/advantage of using QPainter?
