Being able to get the parent of a given node would make traversing the tree much easier

Can you give some details how this would help you in your specific application? There is Walk() which is a public function, which also gives you parent information for each traversed node.

@rivo I have something similar to the demo here https://github.com/rivo/tview/tree/master/demos/treeview . When I press enter and a node which corresponds to a valid file is selected, I want to open that file in a textview. Opening the file for files within folders requires having the name of the parent nodes too

Isn't your actual requirement then to get the entire path to the current node, not just to the parent? Like the breadcrumbs you see on many websites?

If so, a better solution would then be to provide a GetPath(node *TreeNode) []*TreeNode method which gives you all nodes leading to your current node, starting at the root.

What do you think?

Actually, this seems to be simple enough already. As long as the reference is set to the full path (as shown here then its trivial to get the full path of the selected node with GetCurrentNode().GetReference().(string)

Well, I added the function (check out the latest commit) while I was travelling and offline so I only saw your message afterwards. But you are right, in the demo, the full path is stored as a reference object so it's available anyway.
