[SOLVED] How to get QModelIndex needed for QAbstractTableModel::setData?

[phamtv]

I have a QMap with values << ¨Register 1¨ << ¨Register 2¨ initialized as follow:

@
QMap<QString, int> registermap;

for (int i = 0; i < 10; i++)
registermap.insert(QString("Register %1").arg(i), i);
@

In my application, I have an event that signals me to update a particular row (keyed by ¨Register n¨) in the tableview. I am trying to get the QModelIndex needed as an input to QAbstractTableModel::setData

@
QModelIndex currentIndex = registerModel->index(registermap[e->Desc], 0, QModelIndex());
registerModel->setData(currentIndex, e->Value, Qt::EditRole);
@

However, the above implementation always return the value of ¨1¨ even if the e->Desc is ¨Register 9¨... Can someone shine some light on me?

Hard to guess what's going on, we do not know what's your registerModel is based on.

disregard my post... I was handling the signal in the wrong object. What I needed to do was handle the signal in my inherited QAbstractTableModel object and do the following....

@
public slots:
void RegisterValueChanged(QObject* obj, RegData* e)
{
registerMap[e->Desc] = e->Value;
reset();
}
