Original GitHub issue: https://github.com/rivo/tview/issues/379

I'd like my applications to be compatible with real DEC VT terminals. Applications using tcell/tview like to discard colours if TERM=vt*** e.g. vt320. When I was about to fix an application, I couldn't find SetAttribute or something like that for TreeNodes. So for example if I want to set the currently selected TreeNode in a TreeView, for xterm or similar I simply set the color using SetColor. But if I want to indicate that on DEC VT320 for example, I need to set the underline attribute on that node, and I don't have the function for that.

You'll want to prepend the text of your tree node with a color tag [::u]. That should do the trick.
