Changing the title of a column in the QDirModel object

[janca]

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 :



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 :)
