Table view UI update

[ashajg]

Hi guys

I am using Table view.. and trying to update my table view..

TableView {
model: TableModel {}
}


**main.cpp**
qmlRegisterType<TableModel>("TableModel", 0, 1, "TableModel");


**TableModel.h**
QVector<QVector<QString>> m_Model;


**TableModel.cpp**

bool TableModel::setData(const QModelIndex &indexPos, const QVariant &value, int role)
{
    if(data(indexPos, role) == value)
        return false;

    QString key = m_Model.at(indexPos.row()).at(indexPos.column()-1);
    qDebug() << "KEY:" << key;
    m_Model.replace(indexPos.row(),{key, value});
    qDebug() << "Model Data Changed!!!" << m_Model;
    QModelIndex start = index(1,0);
    emit dataChanged(start, indexPos, {role});
    return true;
}

void changeModel() {
       setData(index(1,1), "abc");
}

But my UI is not getting updated
How can I solve this issue?

Thanks!!!

But my UI is not getting updated

does this mean that it still shows the old values or just displays nothing at all?

Hi @VRonin

Thanks for reply!!!

Its Still Showing same values..

[VRonin]

can you try changing emit dataChanged(start, indexPos, {role}); to emit dataChanged(indexPos, indexPos);?

P.S.
Your setData doesn't seem to manage roles correctly but this is another, separate, problem
