Propper Way to a dialog as a delegate

[admkrk]

I have a column in my table view that holds links to either an online PDF, or a local one. The default editor is fine for just adding web links, but more troublesome for adding a file path. I made a dialog where the user can paste a web link, or open a QFileDialog to get the path. I currently have, in createEditor()

else if(header == "Datasheet")
    {
        AddPDFDialog *dialog = new AddPDFDialog(parent);
        connect(dialog, SIGNAL(pdfAdded(QString)),
                this, SLOT(addPDF(QString)));
        dialog->exec();
        model->setData(index, path);
 
        return QStyledItemDelegate::createEditor(parent, option, index);
    }

else if(header == "Datasheet")
    {
        AddPDFDialog *dialog = new AddPDFDialog(parent);
        connect(dialog, SIGNAL(pdfAdded(QString)),
                this, SLOT(addPDF(QString)));
        dialog->exec();
        model->setData(index, path);

        return QStyledItemDelegate::createEditor(parent, option, index);
    }

To copy to clipboard, switch view to plain text mode 

and use

void CompleterDelegate::addPDF(QString path)
{
    this->path = path;
}

void CompleterDelegate::addPDF(QString path)
{
    this->path = path;
}

To copy to clipboard, switch view to plain text mode 

to catch the slot. this->path is a public QString.

It works fine, so far, but it seems like sort of a hack creating the variable. Is there a way to access the slot, directly, inside of createEditor()?
