Changing the title of a column in the QDirModel object

I am using a QTreeView component to display the data of a QDirModel object. How can I change the title of the columns (Name, Size, Type, and Date Modified)? I have tried the following function but it has no desired effect:

// QDirModel m_dirmodel;
m_dirmodel->setHeaderData(0, Qt::Horizontal, "New name"); :confused:

You'll have to subclass QDirModel and reimplement the headerData() method.

Something like this :

Code:

---

QVariant CustomDirModel::headerData(int section,
									Qt::Orientation orientation,
									int role) const
{
	if (orientation == Qt::Horizontal && role == Qt::DisplayRole) 
	{
    	switch (section) 
		{
                case 0:
                    return tr("Arborescence");
                default:
                    return QVariant();
		}
	}
 
	return QVariant();
}

This example applies to a QTreeView with a single column :)

Wow! That's an amazing solution. Thank you. :rolleyes:
