Qt Location send signal when a defined line is crossed
I am trying to make a QML based Race track Lap timer via GPS.
I want to let the user define a line from coordinate A to coordinate B ( the start / finish line ) ,and send a signal when the line is crossed . Unfortunately i can't find a way of doing this .
I made a quick illustration . The red line would be the defined by the user bewteen coordinate A and B . the Blue Dot is the Cars location .
Could someone point me in the right direction ?
I haven't used it yet but QGeoAreaMonitorSource might be what you are looking for.
Hope it helps
