How to turn off selection cells by tab and shif tab in QTableWidget in slot?-CodePudding

I turn on editing some columns of QTableWidget by this

QObject::connect(ui->tableWidgetAdminEmployee, &QTableWidget::clicked,
                     ui->tableWidgetAdminEmployee, [=](const QModelIndex& 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 if i choose editable cell and then start editing it and press tab next cell will be selected and become editable even if it shouldn't

I turned off tabKeyNavigation in QTableWidget, but non-editable cells still can be selected by tab

I tryed this but didn't help

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

It seems you want to handle editing by yourself. This can be a valid approach.

However, you need to disable Qt's default editing capabilities. For your case, I guess turning off all editing triggers is the easiest way (cf edit triggers)

ui->tableWidgetAdminEmployee->setEditTriggers(QAbstractItemView::NoEditTriggers);

Thus Qt will in no way start editing by itself, and you have full control.

Solved

        for(int row=0; row<ui->tableWidgetAdminEmployee->rowCount(); row  ){
        for(int col=0; col< ui->tableWidgetAdminEmployee->columnCount(); col  ){
            auto item=new QTableWidgetItem;
            if(col==0 || col==7 || col==8|| col==9)
                item->setFlags(item->flags() &  ~Qt::ItemIsEditable); //non-editable columns
            ui->tableWidgetAdminEmployee->setItem(row, col, item);
        }
    }
    
    ui->tableWidgetAdminEmployee->setSelectionMode(QAbstractItemView::NoSelection);
    ui->tableWidgetAdminEmployee->setEditTriggers(QAbstractItemView::NoEditTriggers);

    QObject::connect(ui->tableWidgetAdminEmployee, &QTableWidget::clicked,
                     ui->tableWidgetAdminEmployee, [=](const QModelIndex& index) {

        if (ui->tableWidgetAdminEmployee->item(index.row(), index.column())->flags() & Qt::ItemIsEditable )
            ui->tableWidgetAdminEmployee->edit(index);
    });
