DragonCoder

Hi,
On the begin I wanna to say, sorry for my bad english.

I have a little problem withh qml. I'm doing just now a little navigation. Hier is the code

import QtQuick 2.9
import QtQuick.Controls 2.2
import QtQuick.Window 2.0
import QtLocation 5.6
import QtPositioning 5.6



ApplicationWindow {

    id: app_window
    visible: true
    width: 1024
    height: 800
    title: qsTr("Navigation")

    Plugin {
        id: mapPlugin
        name: "osm"
}

    Rectangle {
        id: mapRectangleID
        width: 500
        height: 500
        anchors.horizontalCenter: parent.horizontalCenter
        anchors.verticalCenter: parent.verticalCenter
        Map {
            id: map
            anchors.fill: parent
            plugin: mapPlugin
            center {
                latitude: 59.91//länge
                longitude: 10.75//breite
            }
            zoomLevel: 14
//******************************START POINT******************************//
                MapCircle {
                        id: startPointCircle
                        center {
                            latitude: 59.91
                            longitude: 10.75
                        }
                        radius: 100000.0
                        color: 'green'
                        border.width: 3
                    }
    //******************************FINISH POINT******************************//
                MapCircle {
                        id: endPointCircle
                        center {
                            latitude: 51.20
                            longitude: 12.22
                        }
                        radius: 100000.0
                        color: 'red'
                        border.width: 3
                    }
        }// Map
    } //Rectangle
//******************************START POINT INPUT FIELD BREITE******************************//
        Rectangle{

            id:_ifStartingPoint
            width: 100
            height: 20
            border.color: 'gray'
            border.width: 2
            x: 900
            y: 100

            anchors.left: app_window.right

            TextInput {
                id: txtPlainStartPointLatitude
                anchors.fill: parent
                anchors.margins: 4
            }

        }
//******************************END POINT INPUT FIELD LAENGE******************************//
        Rectangle{

            id:_ifEndPoint
            width: 100
            height: 20
            border.color: 'gray'
            border.width: 2
            x: 900
            y: 150
            anchors.left: app_window.right

            TextInput {
                id: txtPlainStartPointLongitude
                anchors.fill: parent
                anchors.margins: 4
            }

        }

        Button {
            text: "Zeige den weg"
            x: 900;
            y: 200
            onClicked: {
               // map.Longitude = txtPlainStartPointLatitude.Text
                center: QtPositioning.coordinate(latitude= txtPlainStartPointLatitude.Text, longitude= txtPlainStartPointLatitude.Text)
            }
        }

    PositionSource {
    nmeaSource: "socket://127.0.0.1:12345"
    }


}

So I have 2 input fields, where the user can write the latitude and longitude, but i don't know, how i can use this values and send to a variable or use hier

//******************************START POINT******************************//
                MapCircle {
                        id: startPointCircle
                        center {
                            latitude: 59.91
                            longitude: 10.75
                        }
                        radius: 100000.0
                        color: 'green'
                        border.width: 3
                    }

I tried so:

//******************************START POINT******************************//
                MapCircle {
                        id: startPointCircle
                        center {
                            latitude: txtPlainStartPointLatitude
                            longitude: txtPlainStartPointLongitude
                        }
                        radius: 100000.0
                        color: 'green'
                        border.width: 3
                    }

But it doesn't work, have someone any ideas?

And second problem, I have two point, but i don't know, how i can draw a way by using openstreet maps, between 2 points. Can i do that only by qml, or i need python or js? And have someone any links to tutorials, how i can do that?

Thanks for your help and have a nice day

Hi,
try

  onClicked: {
            map.center = QtPositioning.coordinate(parseFloat(txtPlainStartPointLatitude.text),parseFloat(txtPlainStartPointLongitude.text))
 }

It's helped to do a circle on start and end point. Do you know, how i can draw between point A and B, i'm using OpenStreet Maps
