Advice on how to implement a rotating and zooming drawing canvas

[ruakuu]

Oh, you mean I can paint(draw) directly in the scene with the mouse or tablet? As far as I know, you could only do that with classes derived from QPaintDevice, you can add items to the scene but not draw directly in it, that is what I readed in the documentation, or am I missing something here?

Unless Im not explaining myself correctly, I want to actually use the mouse or tablet to scketch there.

I was going to make a class derived from QWidget (also using QImage for loading images), to make me a drawing canvas Widget, then put that in the scene and rotate it with a view. I saw this canvas approach in the Scribble and Tablet examples that comes with Qt. Both make a canvas that derives from QWidget.

I want to make something like the little japanese program called Opencanvas.
