Map not working

Mikeeeeee

Hi!
Map QML not working.
My ui.qml:

import QtQuick 2.12
import QtQml 2.12
import QtQuick.Window 2.12
import QtQuick.Controls 2.12
import QtPositioning 5.12
import QtLocation 5.12

Item {
    width: 400
    height: 650
    visible: true

    Plugin {
        id: mapPlugin
        name: "osm" // "mapboxgl", "esri", ...
        // specify plugin parameters if necessary
        // PluginParameter {
        //     name:
        //     value:
        // }
    }

    Map {
        anchors.fill: parent
        plugin: mapPlugin
        center: QtPositioning.coordinate(59.91, 10.75) // Oslo
        zoomLevel: 14
    }
}

I get error: center: QtPositioning.coordinate(59.91, 10.75) - Line 26: Function not supported in a Qt Quick UI form. (M222)

That's a warning in Qt Creator, right? But when you run the application it works?

Mikeeeeee

The application compiles, but the map does not appear. But it is an example of "places_map" compiles and the map is working.

QtPositioning.coordinate() is not supported in a *.ui.qml file.

The example uses a *.qml file, not a *.ui.qml file: https://doc.qt.io/qt-5/qtlocation-minimal-map-example.html

Mikeeeeee

Put it in a new file .qml, but the map did not appear, only the white screen.

import QtQuick 2.12
import QtQml 2.12
import QtQuick.Window 2.12
import QtQuick.Controls 2.12
import QtPositioning 5.12
import QtLocation 5.12

Item {
    width: 400
    height: 650
    visible: true

    Plugin {
        id: mapPlugin
        name: "osm" // "mapboxgl", "esri", ...
        // specify plugin parameters if necessary
        // PluginParameter {
        //     name:
        //     value:
        // }
    }

    Map {
        anchors.fill: parent
        plugin: mapPlugin
        center: QtPositioning.coordinate(59.91, 10.75) // Oslo
        zoomLevel: 14

        Text {
            id: element
            x: 103
            y: 51
            width: 180
            height: 75
            text: qsTr("Page with my map")
            font.pixelSize: 20
        }
    }
}

I have just tried your code and it works for me.

I just had to change Item to Window as my main component, because I don't use QQuickView (chances are you are not using it either).

Mikeeeeee

From this code I go to the qml-file with the map:

import QtQuick 2.12
import QtQml 2.12
import QtQuick.Window 2.12
import QtQuick.Controls 2.12
import QtPositioning 5.12
import QtLocation 5.12

Window {
    visible: true
    width: 400
    height: 650
    title: qsTr("Name app")

    Loader
              {
                  id: loader
                  anchors.fill: parent
                  //source: "Map.qml"
                  source: "QtMap.qml"
              }
}

Where and how to add QQuickView ?

Don't, there is no need. You already have a Window, so no need to use QQuickView.

Are you sure "QtMap.qml" is being found? Any warnings or error messages are printed? Is it in the same directory as your .exe file at runtime? (I'd expect QML file to be in Qt resource, but you seem to be using relative paths instead)

Mikeeeeee

I get error: qt.network.ssl: QSslSocket::connectToHostEncrypted: TLS initialization failed
The file is there, I see the text :"Page QtQml" on the screen. This text is in the map window.

Check your OpenSSL configuration.

Yes but do you see "Page with my map" text? I suspect the Loader is not seeing your QML file and can't load it.

Either that, or OpenSSL fail prevents maps from being downloaded.

Mikeeeeee

But the sample application works. How do I find and fix OpenSSL errors ?
The loader loaded the file, otherwise I would not have seen the text of this page.

sierdzio

You cited completely different text so I assumed it has not loaded correctly.

Start by typing the error message into your search engine.

But the sample application works.

Did you use different versions of Qt?

Mikeeeeee

No, I used 13.0. But this version normally compiled an example. So it's not about the compiler. The code that I showed above is correct, just that when migrating to another file, I changed the text of the label.
