[Qt-interest] How to find the GPS coordinates of the point where I mouse click on the Google map (embedded in a qt widget), through "Qt" API?

[Anisha Kaul]

I had put the same question on the QtCentre foras, and the people there gave
me a link to the Qt class named "QGraphicsGeoMap". The function there titled
"screenPositionToCoordinate" **looks promising.
