I think that QCanvas is quite unknown and underused. However, it is a bit hard to get all stuff working with it, I once fought for a while to get the main graphics for a simple strategic game working with QCanvas, but after a while I gave up. It was easier to use SDL, even though SDL is more low level.
The Qt tutorial is a good and ambitious project, I look forward to the upcoming chapters.
