How to hide a row of a QTableWidget without changing the index of the entries?

Question

I have a QTableWidget with 7 colums in a QDialog, where every row has information about files in a specific directory. With some checkboxes, lineedits etc I want to have the possibility to show only those files with a certain text, which I can manually add in the lineEdit.

Is it somehow possible to check every row, if it contains the lineEdit-text and if not to hide the row (without changing any index of the other rows, that I dont have to hide)?

From what I understand, in each row there is an item that contains a text, you want those rows to be that text is equal to the text that appears in a QLineEdit. Am I right? – Waltraudwaltz

Yes, exactly. I found this: QTableWidget->hideRow(int i). Does it work with that? – Farnsworth

yes, use the textChanged method of QLineEdit, and in the slot you use iterates over the items, and if it does not meet the criterion, hide the row with that method – Waltraudwaltz

Thank you, it works perfect! :) – Farnsworth

For people who need this possibility, it is quite easy, I do it like this:

for(int i=0; i<tableWidget->rowCount(); i++)
{
    if(lineEdit->text() != tableWidget->(i, 0)->text())
    {
         tableWidget->hideRow(i);
    }
}
