Sorting problem QTableView

[ivanicy]

Hello!!

I am using a QTableView to show some entries of data. I have enabled the sorting but I have a problem. When I want to refresh the table with new data, if I have clicked on a column for sort by it, the table doesn't show the right columns. Look at the image:

I have sorted by "Date Time" column, and when I refresh, it appears like that.

How can I reset the sorting, or something like this, to solve this problem?

Thank you very much!

• What model are you using?
• Are you using a QSortFilterProxyModel?

I am using the default QTableView widget and its methods. I use tableWidget->insertRow() and this kind of methods. I don't know how to use a QSortFilterProxyModel

QTableView != QTableWidget. In any case, what you are doing should work. Can you show us a minimal example to reproduce the problem?

@VRonin Yes, I had a mistake. I am using a QTABLEWIDGET.

The problem is when I want to refresh the table after doing a column sort. So, I can't extract a compilable example, but I can show the steps I am following to do it:

// I have a QStringList vector to save all the rows I want to insert in the table. This is because I apply filters on the information.
std::vector<QStringList> m_vectorTable;

// In the refresh function:
m_vectorTable.clear();
ui->tableEvents->setRowCount(0);
...
ui->tableEvents->insertRow(0);

// slLine.at(x) contains the data I want to insert (it is correct)
QTableWidgetItem *itemColumn0 = new QTableWidgetItem(slLine.at(0));
QTableWidgetItem *itemColumn1 = new QTableWidgetItem(slLine.at(1));
QTableWidgetItem *itemColumn2 = new QTableWidgetItem(slLine.at(3));
QTableWidgetItem *itemColumn3 = new QTableWidgetItem(slLine.at(4));

itemColumn0->setBackgroundColor(QColor(255,0,0,100));
itemColumn1->setBackgroundColor(QColor(255,0,0,100));
itemColumn2->setBackgroundColor(QColor(255,0,0,100));
itemColumn3->setBackgroundColor(QColor(255,0,0,100));

ui->tableEvents->setItem(0, 0, itemColumn0);
ui->tableEvents->setItem(0, 1, itemColumn1);
ui->tableEvents->setItem(0, 2, itemColumn2);
ui->tableEvents->setItem(0, 3, itemColumn3);

// slLineToVector contains the row (its columns are correct)
m_vectorTable.push_back(slLineToVector);
ui->tableEvents->repaint();

One detail more, if I use:

ui->tableEvents->setSortingEnabled(false);
ui->tableEvents->setSortingEnabled(true);

at the beginning and the end of the refresh function, it solve the problem, but keeps the sort configuration. I want to restart the sort configuration to the default one.
