tableWidget does not sort itself

cdwijs

Hi All,
I have a tablewidget, and I cannot get it to sort on the first column. What am I missing?
Cheers,
Cedric

//constructor:
const int IDXSTART = 0;
tableWidget = new QTableWidget(0,9,this);
tableWidget->setHorizontalHeaderLabels(HORHEADERS.split(";"));
QVBoxLayout *centralLayout = new QVBoxLayout;
centralLayout->addWidget(tableWidget);
//add rows to the table
tableWidget->insertRow(row);
tableWidget->setCellWidget(row,IDXSTART,new QDateTimeEdit);
((QDateTimeEdit*)(tableWidget->cellWidget(row,IDXSTART)))->setDisplayFormat(DTFORMAT);
qint64 starttime = dateTimeEdit->dateTime().toMSecsSinceEpoch();
((QDateTimeEdit*)(tableWidget->cellWidget(row,IDXSTART)))->setDateTime(datetime.fromMSecsSinceEpoch(starttime));
//sort rows
void MainWindow::sortRows(void)
{ //sort the lines on date / time in the list.
    tableWidget->setSortingEnabled(TRUE);
    tableWidget->sortByColumn(0,Qt::AscendingOrder);
    //tableWidget->sortItems(IDXSTART); //this does not sort the table
    tableWidget->setSortingEnabled(FALSE);
}

Hi,

AFAIK, the sorting happens on the content of a cell. You don't have anything in your cells, only the widgets set.

Rather than putting a QDateTimeEdit on each cell, you can create your own QStyleItemDelegate that handles the date the way you want it. That would also be better performance wise.

Hi SGaist,
Thanks for the fast reply. Before I dive into this, do you know if there's an example I can study?

Do you mean example of custom QStyledItemDelegate ?

Hi SGaist,
An example of QStyledItemDelegate would be nice.

There's one linked in the documentation of QStyledItemDelegate.
