Rename a QTreeView->header() column??

[killerwookie99]

I am trying to rename a QTreeView->header()-> setColumnText(0, "Rename");

This QTreeView has been initalized like this:

QTreeView *treeView = new QTreeView();
QDirModel *dirModel = new QDirModel();
QSortFilterProxyModel *dirProxyModel = new QSortFilterProxyModel();
 
dirProxyModel->setSourceModel(dirModel);
treeView->setModel(treeProxyModel);
 
// I'd like to rename the column header for this, how?
treeView->header()->setColumnText(0, "Folders");

QTreeView *treeView = new QTreeView();
QDirModel *dirModel = new QDirModel();
QSortFilterProxyModel *dirProxyModel = new QSortFilterProxyModel();

dirProxyModel->setSourceModel(dirModel);
treeView->setModel(treeProxyModel);

// I'd like to rename the column header for this, how?
treeView->header()->setColumnText(0, "Folders");

To copy to clipboard, switch view to plain text mode 

There doesn't seem to be a clear way to do this?
