Wrong function according to parameters is taken

[Lykurg]

Hi,

in my own model I have:

QVariant data(const QModelIndex &index, int role) const;
QVariant data(const QModelIndex &index, BibtexGlobal::SearchFilter role) const;
// BibtexGlobal::SearchFilter is an enum

QVariant data(const QModelIndex &index, int role) const;
QVariant data(const QModelIndex &index, BibtexGlobal::SearchFilter role) const;
// BibtexGlobal::SearchFilter is an enum

To copy to clipboard, switch view to plain text mode 

And in an other class I call:

QModelIndex index = sourceModel()->index(sourceRow, 0, sourceParent);
QHash<BibtexGlobal::SearchFilter, QRegExp*>::const_iterator i = m_filter.constBegin();
while (i != m_filter.constEnd())
{
  qWarning() << sourceModel()->data(index, i.key());
  ++i;
}

QModelIndex index = sourceModel()->index(sourceRow, 0, sourceParent);
QHash<BibtexGlobal::SearchFilter, QRegExp*>::const_iterator i = m_filter.constBegin();
while (i != m_filter.constEnd())
{
  qWarning() << sourceModel()->data(index, i.key());
  ++i;
}

To copy to clipboard, switch view to plain text mode 

But although i.key() is BibtexGlobal::SearchFilter the function data(const QModelIndex &index, int role) is called. Why? Is int and enum for the compiler the same?

Thanks
