Important: Please read the Qt Code of Conduct -

SetData(int role,const QVariant) Data(int role)

  • I'am typing codes in Chapter3,spreadsheet, of C++GUI Programming with Qt4.
    I don't understand why these two methods don't contain parameter "int column". Otherwise, how it locates where the cell is.

  • Not everyone has that book at hand. If you would tell us on which class you call that method, that would be great.

  • Well, all is contained in the [[doc:QModelIndex]]. It contains row, column and parent item. These three together uniquely identify an item in an model.

    Edit: I happen to have the book here, but I can't quickly locate the exact snippet you're talking about.
