The value 1 is the columncount property, that, by default, assumes that value.

Your question was not very clear.

If you want to modify the label, you can use setHeaderLabel/setHeaderLabels functions.

If you want to hide the label, you can use setHeaderHidden function.

Please, before ask, use the Qt documentation.

I came here looking for the same thing this person asking the question was seeking. There is nothing in the QT documentation describing a header - sure there's that function but unless I look through the 30 or so methods, types, and constants in the documentation and examine EVERY one, nobody is going to know what it is - I tried clicking on the 1 and noticed you can't click on it - it doesn't highlight - but that doesn't tell me anything - One would just assume their program isn't working or they don't know properly how to use a QTreeWidget. But this answer helped pointing to a method. – Seth D. Fulmer Mar 22 '20 at 15:24

By default qt designer puts 1 there, you need to edit it to suit your need from within qt designer or programatically using the docs.

This wll change the title of qlistwidget:

self.treeWidget.headerItem().setText(0, QtGui.QApplication.translate("Dialog", "xyz", None, QtGui.QApplication.UnicodeUTF8))
