The class i meant QGraphicsItem, not QGraphicsWidget - my mistake.

Exactly what may solve my problem. How this <img> tag must be crafted. And how 
the c(++) code must look like to be referred ?
So having in the code an QPixmap instance like
  QPixmap pixmap;

filled with the drawing i wnt to have.
How to refer it ?

Thats the reason i want to avoid it.

exactly.

If there is no other way i may go on this track.

The use case may be a genealogy tree and display a picture of the member 
(together with additional info) when hovering a mouse over it. The picture is 
placed in a database, so not referrable by ordinary <img> tags.
