How to set QTableWidget editable with a few non-editable columns, and editing by one click on cell?

@Kuji
The only thing which strikes me is void QAbstractItemView::edit(const QModelIndex &index):

To provide consistent navigation behavior, call setCurrentIndex() before this function with the same model index.

Not saying that is your issue, but does it make any difference if you do this in the slot? Change to a lambda for the slot which calls setCurrentIndex() before edit(), this will also allow you to see whether the problem lies in the connection of clicked() signal to slot or in the call to edit() from the slot.

@JonB Sorry i don't understand can u explain about where i should do this: Change to a lambda for the slot which calls setCurrentIndex() before edit()?

@Kuji

    QObject::connect(ui->tableWidgetAdminEmployee, &QTableWidget::clicked,
                     ui->tableWidgetAdminEmployee, [=](const QModelIndex& index) {
        qDebug() << "In slot";
        ui->tableWidgetAdminEmployee->setCurrentIndex(index);
        qDebug() << "Calling edit()";
        ui->tableWidgetAdminEmployee->edit(index);
        qDebug() << "Called edit()";
        });

Something like that (untested). I don't suppose doing setCurrentIndex(index) will solve your problem, but it's worth a try.

@JonB Added, when i choose cell which is non-editable console writes:
In slot
Calling edit()
edit: editing failed
Called edit()

When i choose editable cells console writes:
In slot
Calling edit()
Called edit()

when i choose cell which is non-editable console writes:

What do you expect otherwise? I mean - it just tells you that a non-editable item can not be edited. So either life with it or don't call edit() on such an item.

I did not realize you were doing this on the non-editable cells! So it is behaving well/as it should, what is the issue? Earlier you wrote:

but when i click on enabled cell in console appears line "edit: editing failed"

Now you show that works fine on editable cells.

[Kuji]

How can i get rid of lines in console:edit: editing failed? By don't calling edit() for these cells then how exclude these cells?

[JonB]

@Kuji

if (ui->tableWidgetAdminEmployee->itemFromIndex(index)->flags() & Qt::ItemIsEnabled )
    ui->tableWidgetAdminEmployee->edit(index);

Something like that.

[Kuji]

@JonB Can't write instead of this code line because of en error, or i should write this in another place?

ui->tableWidgetAdminEmployee->edit(index);

Then fixing the error would be a good start.

[Kuji]

@Christian-Ehrlicher i mean this error

error: 'itemFromIndex' is a protected member of 'QTableWidget'

here

    QObject::connect(ui->tableWidgetAdminEmployee, &QTableWidget::clicked,
                         ui->tableWidgetAdminEmployee, [=](const QModelIndex& index) {
            ui->tableWidgetAdminEmployee->setCurrentIndex(index);
            if (ui->tableWidgetAdminEmployee->itemFromIndex(index)->flags() & Qt::ItemIsEnabled )
                ui->tableWidgetAdminEmployee->edit(index);
            });

[mpergand]

try:
ui->tableWidgetAdminEmployee->item(index.row(), index.column())

[Kuji]

@mpergand This worked

QObject::connect(ui->tableWidgetAdminEmployee, &QTableWidget::clicked,
          ui->tableWidgetAdminEmployee, [=](const QModelIndex& index) {
ui->tableWidgetAdminEmployee->setCurrentIndex(index);
if(index.column()!=0&&index.column()!=7&&index.column()!=8&&index.column()!=9)
if (ui->tableWidgetAdminEmployee->item(index.row(), index.column())->flags() & Qt::ItemIsEnabled )
ui->tableWidgetAdminEmployee->edit(index);
});

But now after making some columns editable i can't make them non-editable

Change the flag of the item accordingly.

[Kuji]

@mpergand I tryed this, but after clicking on the cell it's editable and then it becomes unselectable

    QObject::connect(ui->tableWidgetAdminEmployee, &QTableWidget::clicked,
                     ui->tableWidgetAdminEmployee, [=](const QModelIndex& index) {
        ui->tableWidgetAdminEmployee->setCurrentIndex(index);
        ui->tableWidgetAdminEmployee->item(index.row(), index.column())->setFlags(Qt::ItemIsSelectable);
    });

[mpergand]

@Kuji
Qt::ItemIsSelectable|Qt::ItemIsEnabled

[Kuji]

@mpergand cells are editable when i click on them and after that they are non-editable but write "edit: editing failed" in console

[mpergand]

@Kuji
To tell the truth, i don't understand what you're trying to do from the beginning.

[Kuji]

@mpergand I'm trying by pressing the button make editable some columns and make non-editable some columns in table, then after another button make all table non-editable.
Also i can't disconnect, if i could i would just set table readonly

[mpergand]

QObject::connect(ui->tableWidgetAdminEmployee, &QTableWidget::clicked,

Here you click on a table cell not on a button.
So what button are you talking about ?
