Change cell contents before editing QTableWidget cell?

[Publicnamer]

If the user double-clicks on a cell, it is the current contents of the cell that are what is used in the editing box within that cell.

Is there a way for me to replace the text in the cell just after the double click and just before the cell enters editing mode?

@Publicnamer Use a delegate:

class Delegate: public QStyledItemDelegate{
public:
    using QStyledItemDelegate::QStyledItemDelegate;
    void setEditorData(QWidget *editor, const QModelIndex &index) const{
        if(QLineEdit *lineEdit = qobject_cast<QLineEdit *>(editor)){
            lineEdit->setText("Foo");
        }
    }
};

tableWidget->setItemDelegate(new Delegate);
