Role in setData has no effect

gabor53

Hi,
I have the following in my .h file:

  bool setData(const QModelIndex & index, const QVariant & value, int role = Qt::EditRole) ;

in .cpp:
I have the function:

bool FixDb::setData(const QModelIndex &index, const QVariant &value, int role )
{
    if(role == Qt::EditRole)
        {
            qDebug()     << "Entered setData bool.";
            int rowFix = index.row ();
            int colFix = index.column ();

            qDebug() << "Setdata row: " << rowFix;
            qDebug() << "Setdata col: " << colFix;
        }
    return true;
}

bool setData is called from an other function:

void FixDb::on_tableView_Fix_doubleClicked(const QModelIndex &index)
{
    int row = index.row ();
    int column = index.column ();
    qDebug() << "Fix Index: " << "(" << row <<"," << column << ")";

    QModelIndex fixIndex(index.model()->index(index.row(), 0, index.parent()));
    qDebug() << fixIndex.data(Qt::DisplayRole);
    QVariant v(fixIndex.data(Qt::DisplayRole));
    fixID = v.toString ();
    qDebug () << "Fix ID: " << fixID;

    QModelIndex fixItemIndex(index.model ()->index (row,column, index.parent()));
    qDebug() << fixItemIndex.data (Qt::DisplayRole);
    QVariant fixV;
    fixV = fixItemIndex.data (Qt::DisplayRole);
    itemToFix = fixV.toString ();

    qDebug() << "Item to fix: " << itemToFix;

    QSqlQuery query_getImage;
    query_getImage.prepare ("SELECT Pic FROM Items WHERE ID = :FriendID");
    query_getImage.bindValue (":FriendID",FriendID);

    setData(index, value, role);

In the .h the editRole is set, but clearly it doesn't transfer to the actual bool function in the cpp file as processing does not enter

if(role == Qt::EditRole)

It jumps directly to the return true. Why don't I have the editRole set in the actual function? Thank you.

@gabor53 You are passing some role here:

setData(index, value, role);

Try without passing so that it takes the default value.

setData(index, value);

Thank you.

setData(index, value);

worked.
