print c++ data in qml list view

taedooly

i want to print c++ custom data class in qml list view by delegate.

should i make model in c++ and then call it in qml?

or is there any way call only data in qml??

Hi,

What kind of data are you talking about ?

taedooly

class resource: public QObject
{
Q_OBJECT

public:
    resource(QString);
    ~resource();
    Q_INVOKABLE void addLoss(float, float);
    Q_INVOKABLE float getLoss();
    Q_INVOKABLE QString getName();

private:
    QString name;
    QList<float> *Loss;
};

my data class is above. and i made resource list as bleow

in main.cpp

    QList<resource*> *resourceArr;
    qDebug()<< "declare resourceArr";
    resourceArr = new QList<resource*>;
    resource *a = new resource("name");
    resourceArr->push_back(a);

    QQmlApplicationEngine engine;
    QQmlContext *context = new QQmlContext(engine.rootContext());   // c++ class to qml object
    context->setContextProperty("resourceVec", &resourceArr);

last line gives me an error like "calling a private constructor of class 'QVariant'"
and also "atemp to use a deleted function"

what i want is print resourceArray[idx].getName() / resourceArray[idx].getLoss() in my listView.

problem looks simple but i have a hard time with it..... i'm noob in qt.

You are passing a pointer to the pointer of your QList object. That's wrong.

i Solved this!. it was not matter of pointers, i've misunderstood about QObect.
thanks
