I'm looking for suggestions on how to solve this problem. Basically what I have is a QGraphicsScene with a number of QGraphicPixmapItems. I want the user to be able to take the mouse and draw line trails (not straight lines), sort of like scribling over the image with a red Pen. I then need to be able to save off the trails they drew to a file so that it can be loaded again at a future point in time.
Would the best thing to do is create another GraphicsItem subclass that reads the mouse input and the paints the lines? Or should I subclass the Graphics Scene and add functionality in there?
Just curious what your thoughts are.
Thanks in advance.
