Drag and drop items in view to sort order

[Big Duck]

Hi,

I'd like to sort items in a tree view by dragging and dropping.
My data is a flat list of rows and columns with no heirarchy. I chose not to use TableView as the row headers cant be hidden, is this right ?

I've got as far as subclassing standardItemView and re implementing :
supportedDropActions() const
removeRows(int row, int count, const QModelIndex &parent)

My trouble is what to put in removeRows so that a MoveAction is done on the model. At the moment I get copying of data in the view.

Another problem is that when dragging the treeView item, I get a row with a + as its a treeView Im using, any ideas where I'm going wrong.

Below is what I've got so far

MyModel::MyModel(QObject *parent)
  : QStandardItemModel(parent)
{
}
 
Qt::DropActions MyModel::supportedDropActions() const
{
  return Qt::MoveAction;
}
 
bool MyModel::removeRows(int row, int count, const QModelIndex &parent)
{
  if (parent.isValid())
    return false;
  beginRemoveRows(parent, 0, 0); 
// What am I doing here?
  endRemoveRows();
  return true;
}

MyModel::MyModel(QObject *parent)
  : QStandardItemModel(parent)
{
}

Qt::DropActions MyModel::supportedDropActions() const
{
  return Qt::MoveAction;
}

bool MyModel::removeRows(int row, int count, const QModelIndex &parent)
{
  if (parent.isValid())
    return false;
  beginRemoveRows(parent, 0, 0); 
// What am I doing here?
  endRemoveRows();
  return true;
}
