For a test I created a dummy event @25min in this way: add_event(&dive->dc, 60*25, SAMPLE_EVENT_AIRTIME, 0, 0, "Minimum gas exceeded"); When looking for add_event I stumbled across s.th.: I know that one has to be careful where and when it is ok to translate the name of an event. But my guess is that for this event (line 195, diveprofileitem.cpp) we would be allowed to translate it: add_event(&displayed_dive.dc, entry->sec, SAMPLE_EVENT_CEILING, -1, max / 1000, "planned waypoint above ceiling"); What do you think? Ok to change this to: add_event(&displayed_dive.dc, entry->sec, SAMPLE_EVENT_CEILING, -1, max / 1000, translate("gettextFromC", "Planned waypoint above ceiling")); And then there is another one in planner.c where I'm not sure: add_event(dc, lasttime, SAMPLE_EVENT_PO2, 0, po2, "SP change"); Best regards Stefan -- Stefan Fuchs E-Mail: sfu...@gmx.de <mailto:sfu...@gmx.de>
