You need QtCanvas, the qt4 "port" of QCanvas, and not Q3Canvas which is the qt3 support version of QCanvas for qt4 (yes its quite complicated!).

(BTW, the best place to get support for Qanava is on its homepage (with all due respect for QtCentre!)

Qanava 0.0.7 will be out soon, so you might want to wait one day or two, since it will get rid of all that Q*Canvas stuff to be a standalone widget with Arthur painting (what a scoop!).
