QTableView horizontalHeader()->setStretchLastSection(true) and resizeColumnsToContents

[Abdurahman_Gulamkadirov]

Hi there.
I'm confusing in this situation: There's a QTableView in GUI. And it takes my custom table model. When GUI is shown, my program loads data from rest api to the table:

QJsonArray arr = QJsonDocument::fromJson(reply->readAll()).array();
       for(int i = 0; i < arr.size(); ++i)
       {
           QJsonObject obj = arr[i].toObject();
           modelInvoiceItem->insertProduct(obj);
       }
       ui->tableInvoiceItem->resizeColumnsToContents();
       ui->tableInvoiceItem->horizontalHeader()->setStretchLastSection(true);

but the last horizontal header doesn't stretch.

Can only suggest: look at your setting for enum QHeaderView::ResizeMode on the whole view/individual sections., and maybe comment out resizeColumnsToContents(); while you see how it behaves?

Also, I don't think resizeColumnsToContents(); has any effect until the table view is shown/resized. I think it's usually used in widget's resize or resizeEvent.

I don't know, but does it make any difference if you swap the order of the last two lines?

[Abdurahman_Gulamkadirov]

@JonB No, it didn't help

Like all other widgets, your QTableView is on a layout, isn't it? Nothing will work unless it is.

@JonB yes, it's in a layout

@JonB I tested it after inserting row:

qInfo() << ui->tableInvoiceItem->horizontalHeader()->sectionResizeMode(
                ui->tableInvoiceItem->horizontalHeader()->count() - 1);

it shows QHeaderView::Stretch. But the last section doesn't fill extra spaces. When I resize window, it automatically fills.

@JonB setting ui->tableWidget->horizontalHeader()->setSectionResizeMode(QHeaderView::ResizeToContents); helped, thanks a lot!
