Printing a QMap with a ListView

Pantoufle

Hello,

I'm trying to display a QMap<int, QString> that I have on the C++ side in a ListView present on the QML side. I cannot turn it in a QStringList because I will need the keys of QMap later on this Listview.
I'm not sure how to proceed, but after some research I saw that I had to use a QVariantMap to pass my QMap to my QML:

C++ Code (_userList is a QMap<int, QString> previously filled):

QVariantMap User::usersMap()
{
    QVariantMap myVariantMap;
    QMapIterator<int, QString> j(_usersList);
    while(j.hasNext()) {
        j.next();
        myVariantMap[QString::number(j.key())] = j.value();
    }
    return myVariantMap;
}

QML :

ListView {
       id: userListView
       spacing: 5
       anchors.fill: parent

       model: user.usersMap()

        delegate:
            RowLayout {
            anchors.left: parent.left
            anchors.leftMargin: 25
            spacing: 20
      
                Text {
                    text: modelData
                    anchors.left: parent.left
                    anchors.leftMargin: 75
                    font.pixelSize: 28
                    color: "white"
                }
            }
    }

My biggest doubt is about the initialization of the "model" field in QML and accessing it via modelData. If you have any clues or advice on how to display this QMap<int, QString>, I thank you in advance.

You can try something like this.

ListView {
    id: userListView
    spacing: 5
    anchors.fill: parent
    property var maps : user.usersMap();
    property var keyss : Object.keys(user.usersMap())
    model: keyss

    delegate:Text {
        text: modelData + " Value = "+userListView.maps[modelData]
        anchors.leftMargin: 75
        font.pixelSize: 28
    }
}
