QUESTION
I'm trying to store lat/lng on mouse click to geometry Point.
So basically when user clicks on map i need to get those coordinates(lat/lng) and store them to variable for example point = Point(lat, lng)
so i can calculate nearest geometry and pull data from PostGIS.
I'm aware i need to establish backend and @pyqtSlot(float,float)

In this case you must create a Backend

setting, the parameter that it receives depends on what you are sending it, in the case of the e.latlng
is a QJsonValue
. In the slot you must separate the necessary parts.

I added Global vars: Earth and myReq(for canx the request) the entire code is:
