    Hi all,

    I have a QAbstractTableModel subclass containing a timer, so it send the update signal every second.

    The problem is that, if I use more than 1 second to write, tableView updates itself while I'm editing, deleting what I wrote.
    So how can I stop the update signal when I'm editing the view?

      Hello,
      You can use QObject::blockSignals or the utility wrapper class QSignalBlocker.

      Kind regards.

        Thanks a lot for your answer.

        I've already seen it, but how can I know when the user is editing a cell? is there some signal emited like startEditing(), end endEditing() ?

        I cannot find it in documentation

          I don't know, and that wasn't your original question. One thing you could try is to subclass the view and reimplement the edit() method from where you can emit a signal that notifies you when editing has started. I hope that helps.

          Kind regards.
