Can a QCompleter emit a signal of index of position of its inside list, by clicking?

Unfortunately the row number is in the filtered list not the full model. The completer is using a proxy model internally. Unfortunately that model is undocumented/private or we might be able to use QAbstractProxyModel::mapToSource().

Interesting, didn't know that.

So alternatively one could do something like

QModelIndex baseIndex = index;
while (QAbstractProxyModel *proxy = qobject_cast<QAbstractProxyModel*>(baseIndex.model()) {
    baseIndex = proxy->mapToSource(baseIndex);
}
int row = baseIndex.row();

QModelIndex baseIndex = index;
while (QAbstractProxyModel *proxy = qobject_cast<QAbstractProxyModel*>(baseIndex.model()) {
    baseIndex = proxy->mapToSource(baseIndex);
}
int row = baseIndex.row();

To copy to clipboard, switch view to plain text mode 

But using a completer subclass is definitely cleaner.

No, but the modified QCompleter is more general than that

Point taken.

In a bit of circular logic, I suppose you could give a table model-based completer to a line-edit based delegate in a QTableView that uses the same model as the view to emulate what happens when editing a real spreadsheet - as you type a new entry, it shows completed entries based on what has already been entered into the column.
