How to find the coordinates of all objects on the map?

Hi!
I use OSM map.
How to find the coordinates of all objects on the map?
And how do I know the number of objects on the map?import QtQuick 2.12 import QtQuick.Window 2.12 import QtLocation 5.12 import QtPositioning 5.12 Item { visible: true width: 480 height: 720 property double old : 19 property double now Rectangle { anchors.fill: parent color: "#eee" Plugin { id: plugin name: "osm" PluginParameter { name: "osm.useragent"; value: "My great Qt OSM application" } } Map { id: maps anchors.fill: parent plugin: plugin gesture.enabled: true gesture.acceptedGestures: MapGestureArea.PinchGesture | MapGestureArea.PanGesture | MapGestureArea.FlickGesture gesture.flickDeceleration: 3000 zoomLevel: 19 center: QtPositioning.coordinate(55.845741, 37.660652) // Moscow onCenterChanged: { geocodeModel.query = visibleRegion.center() geocodeModel.update() } minimumZoomLevel: 1 focus: true GeocodeModel { id: geocodeModel plugin: plugin onLocationsChanged: { console.log("onLocationsChanged") if (count == 1) { console.log("street:" + geocodeModel.get(0).address.street ) console.log("district:" + geocodeModel.get(0).address.district ) console.log("city:" + geocodeModel.get(0).address.city ) console.log("county:" + geocodeModel.get(0).address.county ) console.log("state:" + geocodeModel.get(0).address.state ) console.log("countryCode:" + geocodeModel.get(0).address.countryCode ) console.log("country:" + geocodeModel.get(0).address.country ) console.log("postalCode:" + geocodeModel.get(0).address.postalCode ) console.log("text:" + geocodeModel.get(0).address.text ) //console.log("bounds:" + geocodeModel.bounds) } } } } } } -
Maybe it can be implemented through PlaceSearchModel ?

Connected PlaceSearchModel and set the search area.
Please tell me how to get from Place Search Model the number of objects and their coordinates?import QtQuick 2.12 import QtQuick.Window 2.12 import QtLocation 5.12 import QtPositioning 5.12 Item { visible: true width: 480 height: 720 property double old : 19 property double now Rectangle { anchors.fill: parent color: "#eee" Plugin { id: plugin name: "osm" PluginParameter { name: "osm.useragent"; value: "My great Qt OSM application" } } Map { id: maps anchors.fill: parent plugin: plugin gesture.enabled: true gesture.acceptedGestures: MapGestureArea.PinchGesture | MapGestureArea.PanGesture | MapGestureArea.FlickGesture gesture.flickDeceleration: 3000 zoomLevel: 19 center: QtPositioning.coordinate(55.845741, 37.660652) // Moscow onCenterChanged: { geocodeModel.query = visibleRegion.center() geocodeModel.update() mySearchModel.searchArea = visibleRegion.boundingGeoRectangle() //it's work mySearchModel.update() } minimumZoomLevel: 1 focus: true PlaceSearchModel { id: mySearchModel plugin: plugin searchArea: visibleRegion.boundingGeoRectangle() onSearchAreaChanged: //it's work { console.log("onSearchAreaChanged :" ) } } GeocodeModel { id: geocodeModel plugin: plugin onLocationsChanged: { // console.log("onLocationsChanged") // if (count == 1) { // console.log("street:" + geocodeModel.get(0).address.street ) // console.log("district:" + geocodeModel.get(0).address.district ) // console.log("city:" + geocodeModel.get(0).address.city ) // console.log("county:" + geocodeModel.get(0).address.county ) // console.log("state:" + geocodeModel.get(0).address.state ) // console.log("countryCode:" + geocodeModel.get(0).address.countryCode ) // console.log("country:" + geocodeModel.get(0).address.country ) // console.log("postalCode:" + geocodeModel.get(0).address.postalCode ) // console.log("text:" + geocodeModel.get(0).address.text ) // //console.log("bounds:" + geocodeModel.bounds) // } } } } } } -
Learned that the number of found facilities can be to know so
console.log("count :" + mySearchModel.count)But the question becomes about finding, tried not to search, or asked, but still nothing looking for
my SearchModel.searchTerm = ""Also tried to enter the search number of the house on the screen, too, is not looking for anything
mySearchModel.searchTerm = "211 K2"But the name of the store finds the object
mySearchModel.searchTerm = "Golden Babylon"By street names, it displays the number of visible areas expensive:
mySearchModel.searchTerm = "prospect Mira"The index also gives 1 result, apparently district. Please tell me how to search to get all the buildings?

@Mikeeeeee I see you in that forum frequently. You ask something about a map application. But no one answers sometimes. Even so, you learn so much! I am just writing to celebrate your effort :D
Good work!
Note: In general, you don't ask questions like "How can I see the building numbers on map?" on coding forums. You should get in to it more, and ask questions like "I got a variable like that and a function like that and how can I expose them?" and so... -
Thanks. I tried asking the question "How can I see the building numbers on map?", but no one answers it. So I ask a question about the code and I hope that someone worked with it.
Now I stopped at "PlaceSearchModel", I hope that someone knows how to solve it. -
There is a property: Place.UnspecifiedVisibility , it should show the field of view for the entire property. Can this can be as the fasten? Or maybe you can somehow get all the objects from the map and drive them through the Place.UnspecifiedVisibility ?
