Set the header text of a QTreeView header

It may be done in your model class that probably inherits QStandardItemModel.

Typically, you would call:

QStandardItemModel::setHorizontalHeaderLabels ( const QStringList & labels )

for text only, or

 QStandardItemModel::setHorizontalHeaderItem ( int column, QStandardItem * item )

if more customization is needed in the header items.

Ah... anyone getting frustrated with this with PyQt5 might like to try this:

self.ui.treeView.setHeaderHidden( False )
