QML ComboBox access in C++ with QComboBox

rmfabac

Hello,

I've created a ComboBox inside of QML that I'm wanting to manipulate in my main.cpp using a QComboBox object. Is this possible using the following?

I need to get the current selected text in C++ to perform some logic. The ComboBox is populated with a JSON file.

main.cpp

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);
    // Hide mouse curser.
    QGuiApplication::setOverrideCursor(QCursor(Qt::BlankCursor));

    // Load gauge UI.
    QQmlEngine engine;
    QQmlComponent component(&engine, QUrl(QStringLiteral("qrc:/main.qml")));
    object = component.create();

    QObject *comboBoxTracks = object->findChild<QObject*>("cboTracks");

    if (comboBoxTracks)
    {
        QStringList list = jsonDoc.object().keys();
        comboBoxTracks->setProperty("model", list);
    }

main.qml

ComboBox {
            id: cboTracks
            objectName: "cboTracks"
            currentIndex: -2
            x: 8
            y: 365
            width: 200
            height: 30
            style: ComboBoxStyle {
                textColor: "#000000"
                background: Rectangle {
                    color: "#000000"
                    border.width: 1
                    border.color: "#ffffff"
                    antialiasing: true
                }
                label: Label {
                    text: "Select Track..."
                    verticalAlignment: Text.AlignVCenter
                    font.pixelSize: 14
                    color: "#ffffff"
                }
            }
        }

@rmfabac Have a look into these documentation. Talks about so many way for QML and C++ interaction.
