How do I make a toolbar button that changes color along with a lua script state?

[JonasHAnd]

Hi!

I have a lua script that mimics Pro Tools "Insertion Follows playback".
Pressing N toggles between the two states.

I'd like to create a toolbar button that becomes blue when "insertion follows playback is" Active. This way I can see the state of the script visually.

The problem is that this only works with regular toggle actions from the action menu, not scripts.

I've read something about the actions "Dummy toggle" and "Exclusive toggle" perhaps being able to do what I need, but I'm not sure how...

If someone could teach me how to do this I'd be grateful.

It's up to the script to set and update its toggle state.

Ok, can I assume that this script does not report its toggle state?
(Since I can get regular toggle actions to toggle toolbar button color but not this script)

So how do I modify this script so it reports it's toggle state;

state = reaper.HasExtState("playtoggle", "togglevalue")

if state then
value = reaper.GetExtState("playtoggle", "togglevalue")
if value == "1" then
reaper.SetExtState("playtoggle", "togglevalue", "0", true)
else
reaper.SetExtState("playtoggle", "togglevalue", "1", true)
end
end

if not reaper.HasExtState("playtoggle", "togglevalue") then
  return
end

local scriptSection = ({reaper.get_action_context()})[3]
local scriptId = ({reaper.get_action_context()})[4]

local value = reaper.GetExtState("playtoggle", "togglevalue")
value = value == '1' and 0 or 1

reaper.SetExtState("playtoggle", "togglevalue", value, true)
reaper.SetToggleCommandState(scriptSection, scriptId, value)
reaper.RefreshToolbar2(scriptSection, scriptId)
