I've been trying to use this to get the subtrees to highlight, and so
far I can only get the first subtree to highlight correctly. Here's the
syntax of what I'm trying.
local subtree = (tree:add(my_proto, tvb:range(), "my header")) -- works
local mytree = (subtree:add("TEST ", tvb:range(0x1), "STUFF")) --
doesn't highlight
I know that wireshark can highlight the subtrees just by looking at the
ethernet filters in the hex pane, but for some reason this isn't
highlighting there. What should I do to get this to highlight. The way
I figure this should work is the first one highlights the entire tvb,
which it does, and the second should highlight all but the first byte,
which it doesn't.

display with LUA
Lua uses the very same API that dissectors use. For protocol tree items
created with Lua (when they are given a tvbRange) the bytes in the hex
dump pane get highlighted as with any other dissector.
