<![CDATA[How do I remove header labels from my tree view?]]>If you just set the header labels with "model.setHorizontalHeaderLabels", it will still keep the old labels if the list of new labels is shorter than the previous labels. For example:

        self.setHorizontalHeaderLabels(["test", "test2"])
        self.setHorizontalHeaderLabels(["test3"])

After running this code in my item model, the header looks like this:
cd71cad2-1eeb-4b06-b2f3-5185f8ac10d6-image.png

Clearly "test" was overwritten, but test2 stays. How can I remove test2? There are no items that go in its column.

Use an empty string for that column.
