The QTreeView documentation states that it contains a QHeaderView object called "header"

The QHeaderView documentation states that it contains a method called "setResizeMode"
https://het.as.utexas.edu/HET/Software/P...rview.html
However when I try to reference that method from in code I get the following error:

However when I try to reference that method from in code I get the following error:
self.header().setResizeMode(1, QHeaderView.Stretch)
AttributeError: 'QHeaderView' object has no attribute 'setResizeMode'The code I am including has the above reference remarked out so that it works and you can see what the end product looks like however if you remove the comment marker from that line you will get the above error when you run it. As denoted within the code this is how I would expect it to be reference and the closest that I got rendering that I can tell because it actually references the QHeaderView class -- the others do not get that far but they are also included for example completeness just in caseimport sys
