Hi Falke, Now I got it. So user selects a rectangle on the image and corresponding lines from the box file highlighted somehow to enalbe the former to put some custom information there or save the fragments as a separate image-box pair. Is this vision correct?
If so, at first glance it seems to me that such functionality would be more appropriate for another (separate) application. GUI would be different: - spread sheet is needed to work with box files - selection of image regions and displaying of those should be convenient But from the implementation complexity point of view it doesn't look like a big deal for QT.
