Access QAbstractItemModel in QML

ODБOï

Hello,

I implemented a QAbstractItemModel just like in this exemple : https://wiki.qt.io/How_to_Use_a_Custom_Class_in_C%2B%2B_Model_and_QML_View

My probleme is that i can't find the way to access that model in a javascript function

With a Qml ListModel it would be : modelName.get(index).roleName

//main.cpp
 VarList vars;
  engine.rootContext()->setContextProperty("mod",&vars);

//qml
     function goToVarId(_vind){  // how to implement this ?
         // find  the varId with value === _vind 
         // position view at that index 
}

    ListView{
           model : mod.model
        delegate:Rectangle{
            height: 16*13
            width: parent.width
            Text{
                height:13
                text : "variable id : " + edit.varId + "<br>" +
                       "variable name : " + edit.varName + "<br>" +
                       "alias : " + edit.varAlias + "<br>" +
                       "slave id " + edit.slaveId                    
            }
        }
 }

Thx

Add a Q_INVOKABLE method in C++ which will return the row for given _vind. Then use it in your QML function to set the current index to your desired position.

@sierdzio hi, thank you. I did as you suggested

    Q_INVOKABLE QString getAlias(int ind){
        QModelIndex nIndex = m_model->index(ind,0);
        QVariant l=m_model->data(nIndex);
        AbsKemVar v = l.value<AbsKemVar>();
        qDebug()<<v.varAlias();
        return v.varAlias();
    }
