One close-button object was used for all dive pictures. This seems like a brittle premature optimization and the pixmap is shared anyway. Make the button a subobject of the dive picture object. Change the object-hierarchy to be based on QGraphicsItem instead of QObject. The QObject here is only used as a kludge to support signals and properties (the latter are necessary for animations). Remove a comment, which does not seem to be relevant after this change. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
