The number of dives was updated when the model of the list was changed. Since we removed the multi-threading, the model is not disconnected/connected anymore and therefore we don't get the appropriate signal. Instead of introducing a different signal, make the shown-value a Q_PROPERTY. Thus, we can easily send a changed signal if we have to. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
