QTableView Model data change Error.

[Pada_]

I use Linux 64Bit for Qt 5.4.

You want to set the Model in the QTableView.

We have not set backgroundColorRole in the data function of the model.

I want to change the background color of the 0,0 index after the model is created and set in the QTableView.

QModelIndex index = model-> index (0,0);
model-> setData (index, QColor (Qt :: blue), Qt :: BackgroundColorRole);

model's setData has not been overridden.
The color does not change. How do I change it?

@Pada_ said in QTableView Model data change Error.:

model's setData has not been overridden.

Then how should it work at all? https://doc.qt.io/qt-5/qabstractitemmodel.html#setData
