Well I overcome the problem for now, I delete the MyCanvas and recreate it again on end of resize. Not the best solution, but for now it works...
Now I have another problem. If I have a QDilaog or QWidget object in nonmodal on top of the SFML window I can't get back the focus of the mouse on that object. The focus stays on the SFML. Interesting that the mouse wheel works at is should be, but the other functions (mouse move/click) are never send to the object. Always stay on the SFML.
Any solutions on that?

I can't make more minimal code then this in order to reproduce the problem.

I think this is exactly the same issue http://en.sfml-dev.org/forums/index.php?topic=12952.15. So how to change the videomode after the window has been created?

Well I spoke too soon. It seems that the SFML windows IS NOT resized after all
I did to test it this time
which is resulting in this
So where would the problem be?

void MyCanvas::resizeEvent(QResizeEvent *event)

setSize(sf::Vector2u(event->size().width(),event->size().height()));
qDebug() << "RESIZED SFML" << getSize().x << getSize().y;
}
{

setSize(sf::Vector2u(event->size().width(),event->size().height()));

Well I am now sure that the SFML window is resing along with the Qt widget, so the problem is somewhere else. When I check the viewport size I get 1000/1000, is this value real pixels or just indicating 100% from the SFML window. Because it stays constant during the resize

Sorry but can you explain a bit more in details. Because I am resizing the MyCanvas manually when I resize the main window. So basically I am resizing the SFMLCanvas widget. Does that means the RenderWindow also gets that event?

OK, maybe there is something wrong in the implementation that I did.
I am receiving the resize event in the MyCanvas, but how can I be sure that I am also resizing QSFMLCanvas which is the base class of MyCanvas? Because what I am thinking is that MyCanvas is resizing, but the event is not send to QSFMLCanvas too, so it stays the same size.

I will make a small demo and will post it here (yes minimal and complete code 
) so you can test and if possible find the solution for it.

Well I am implementing this tutorial http://sfml-dev.org/tutorials/1.6/graphics-qt.php,
and I am getting the resize event in the MyCanvas class.
I have to say that the MyCanvas is itself called as variable in a Qt Widget, thus embedding the MyCanvas (SFML).

So what could the problem be? I can see that the window itself is resizing (the clear color is resized OK) but for some reason all is cropped if outside of the original size of the window.
