Also a quick question, does digikam use some QCanvas to display images?
The reason is that to annotate image with tags, one doesn't want to draw rectangles and so o on the image itself, but have another layer of widgets on top, for example for face recognition draw a box around and have a label below, which can be edited etc. on a layer above. I don't know if canvas has an ability to do this, unless it can be done differently.

The idea is somewhat similar to panes in Java: java.sun. com/docs/ books/tutorial/ uiswing/ components/ rootpane. html
