use custom mimedata between two windows

[prasad_N]

So you are saying that this works

QMimeData*  myModel::mimedata(const QModelIndexList& indexs) const
{
    QMimeData* mime = new QMimeData();
   return mime;
}

QMimeData*  myModel::mimedata(const QModelIndexList& indexs) const
{
    QMimeData* mime = new QMimeData();
   return mime;
}

To copy to clipboard, switch view to plain text mode 

but this

QMimeData*  myModel::mimedata(const QModelIndexList& indexs) const
{
    QMimeData* mime = new MyMimedata();
   return mime;
}

QMimeData*  myModel::mimedata(const QModelIndexList& indexs) const
{
    QMimeData* mime = new MyMimedata();
   return mime;
}

To copy to clipboard, switch view to plain text mode 

doesn't?
I.e. an empty mime data object, default construced, in both cases?

Yes, absolutely..
