Changing global alpha (Transparency)

[Contadotempo]

Hello,
Is it possible to change the global alpha/transparency of all the contents on the window at once or do I have to change it individually for each object?

I tried using sf::RenderWindow::Clear(sf::Color(255,255,255,0)) but I believe that only changes the background settings with which the screen is cleared.

Thanks in advance

There's no easier way than changing it for every object, except if you use SFML 2.

I'm still using SFML 1.6  but that's fine no big deal.
Thanks for the flash-like fast reply!
