A QTreeWidget is a QTreeView (it inherits it), so any function you can call on a QTreeView, you can also call on a QTreeWidget.

You can get the (only) header from a QTreeView (and therefore also from a QTreeWidget) using its QTreeView::header() member function. For example:

QTreeWidget *treeWidget = new QTreeWidget(this);
QByteArray saved = treeWidget->header()->saveState();
