QSqlTableModel resize on edit

Seb Tur

Is there a way to resize the column to content after user put a proposed change in a cell but still hasn't submitted the change?
So QSqlTableModel set to QTableView with ManulSubmit as the EditStrategy.
A user enters cell but he cannot see entire text after he pressed enter.

I can capture the setData that is triggered after submit but this is too late.
I have set resizepolicy on view and on columns but it's not dynamic.

    sql_model_serie->setTable("DokSerieMag");
    sql_model_serie->select();
    ui->TV_serie->setModel(sql_model_serie);
    ui->TV_serie->hideColumn(ui->TV_serie->header_column("dokseria_id"));
    sql_model_serie->setEditStrategy(QSqlTableModel::OnManualSubmit);

    ui->TV_serie->resizeColumnsToContents();

    ui->TV_serie->setSizeAdjustPolicy(QAbstractScrollArea::AdjustToContents);

    ui->TV_serie->horizontalHeader()->setResizeContentsPrecision(-1);
            for (int col = 0; col < ui->TV_serie->model()->columnCount(); ++col)
                ui->TV_serie->resizeColumnToContents(col);
            ui->TV_serie->horizontalHeader()->setStretchLastSection(true);

@Seb-Tur
FWIW did you try calling resizeColumnsToContents() again immediately after the user finished editing the cell?

I didn't find any onEditingFinshed signals
I just found some other that are triggered only after data is submitted.
Normally a user can edit multiple cells and hit Submit only after all of them are ready - in the meantime the edited ones that do not fit to column are truncated with ....

I would be rather annoyed when the cells would resizing during my edits... even afterwards it will not be a good ui design.

@Seb-Tur said in QSqlTableModel resize on edit:

Search QAbstractItemView Class (inherited by your QTableView) for everything to do with itemDelegate. Then QAbstractItemDelegate Class for stuff to do with Editor/ModelData. This is how editing in a QTableView works. For your purpose you can hopefully avoid having to subclass to override virtual methods (though you could do that) by connecting to void QAbstractItemDelegate::closeEditor(QWidget *editor, QAbstractItemDelegate::EndEditHint hint = NoHint) signal?
