[Qt-interest] QTableWidget refresh

[Malyushytsky, Alex]

You should not need any repaint there.
On the first glance code look ok, but the problem might be not in the code you posted.

The code you posted is far from completeness.
I can guess, but there is no guarantee I do it right.

Just for example:
 - this function might be never called
 - you could call tableWidgetChat->setUpdatesEnabled(false); somewhere
 - chatAccountList.count() may not be equal to tableWidgetChat->rowCount ();
 - combobox might have not data set for Qt::UserRole set

Certain questions are better answered using debugger.
Small compilable example might provide enough information, so someone will do it for you.
Most of the time writing such example is sufficient to find a problem.

Regards,

Alex

Thats my function. It's triggered when you press a button.
The table has 3 rows (username, password, protokoll).
{
chatAccount newAccount ={ui->lineEditChatUsername->text(),ui->lineEditChatPassword->text(),ui->comboBoxChatProtokoll->itemData(ui->comboBoxChatProtokoll->currentIndex()).toString()};
int nextAccountNr = chatAccountList.count();
chatAccountList.append(newAccount);
QTableWidgetItem *chatUsername = new QTableWidgetItem(ui->lineEditChatUsername->text());
ui->tableWidgetChat->setItem(nextAccountNr, 0, chatUsername);
QTableWidgetItem *chatProtokoll = new QTableWidgetItem(ui->comboBoxChatProtokoll->itemData(ui->comboBoxChatProtokoll->currentIndex()).toString());
ui->tableWidgetChat->setItem(nextAccountNr, 0, chatProtokoll);
ui->lineEditChatUsername->clear();
ui->lineEditChatPassword->clear();
ui->tableWidgetChat->repaint();
}

Its a little bit hard to find the error on that two line description, can you post your code of adding/deleting table entries?

Hello,

When I add or delete columns to my table I can't see them.

I already tried QTableWidget->repaint(), and refresh, but that didn't work.


Any ideas?..

Thanks.
