Combobox in Qtableview

[n-2204]

Hi,
adding those that appear in guesslist code-

for (int i = 0; i < guesslist.count(); i++) 
    {
        if (combo->findText(guesslist[i]) != -1)//-1 means "not found"
        { 
            continue;
        }
        else {
            combo->addItem(guesslist[i]); //Add to QCombobox
        }

///remove which are not in the guess list code below I tried multiple times but this is not working correctly ? I don't want to change my selection when any item added / removed / replaced ..Plz help😞

QStringList itemsInComboBox;
 for (int index = 0; index < guesslist.count(); ++index) {  //check in list
    for (int item = 0; item < combo->count(); ++item) {  //check in combobox
        itemsInComboBox << combo->itemText(item);
        qDebug() << "before remove " << itemsInComboBox;
                  if ( guesslist[index] != itemsInComboBox[item]  )
                  combo->removeItem(item);
        }
     }

Thanks in advance

Have another loop/iterator through all the items which are in the combo box and remove any which are not in the guess list now

for me this way is not working any how selection of combobox is going away..
how can i store the selection of combobox ?

@n-2204 https://doc.qt.io/qt-5/qcombobox.html#currentIndex-prop or currentText() if you can't relay on the order of the items or itemData() if you use roles, later on you can find the same text with different index, if that's the case, using findText() or findData().

Do you read any documentation at all? It's all there in clear text.

The whole thing, for what I think you say you want:

QString selected = combo->currentText();
combo->clear();
combo->addItems(guesslist);
combo->setCurrentText(selected);

From my code all you need to restore the selection is the combo->setCurrentText(selected);.
