How do you disable expansion in QTreeWidget/QTreeView?

Question

I just want a tree without those arrows that you click on to expand, I want everything to already be expanded and disallow expansion/unexpansion, is that possible?

Answer 1

You can use something like...

/* Expand all items in tree */
tree_view.expandAll(true);

/* Disable interactive expand/collapse */
tree_view.setItemsExpandable(false);

That should get you what you want.
