Hi zork,

Thank you for those nice references, and let me ask step by step.


About Default "classicon.lua":

1. On default oUF's default "classicon.lua" there is "PreUpdate" and "PostUpdate" functions. I understand when they are triggered, but ain't sure of what they actually process. Could you please explain me, if you know about them?


About your "oUF_Harmony.lua":

2. On your "oUF_Harmony.lua", it contains the following codes:

local w = 64*(max+2)
bar:SetWidth(w)
for i = 1, bar.maxOrbs do
  local orb = self.Harmony[i]
  if i > max then
     if orb:IsShown() then orb:Hide() end
  else
    if not orb:IsShown() then orb:Show() end
  end
end
for i = 1, max do
  local orb = self.Harmony[i]
  local full = num/max
  if(i <= num) then
    if full == 1 then
      orb.fill:SetVertexColor(1,0,0)
      orb.glow:SetVertexColor(1,0,0)
    else
      orb.fill:SetVertexColor(bar.color.r,bar.color.g,bar.color.b)
      orb.glow:SetVertexColor(bar.color.r,bar.color.g,bar.color.b)
    end
    orb.fill:Show()
    orb.glow:Show()
    orb.highlight:Show()
  else
    orb.fill:Hide()
    orb.glow:Hide()
    orb.highlight:Hide()
  end
end

If I'm going set the appearance of "Chi Orbs" outside of this module, do I still have to have

local w = 64*(max+2)
bar:SetWidth(w)

and

second "for" loop?

3. Where does "bar.maxOrbs" come from?

4. How does "ForceUpdate" and "Path" functions work?

5. On "ForceUpdate" function and "Enable" function, there is "element.__owner". Does "__" mean something special in Lua when you are indexing an element from table?




Please excuse me if I'm asking too many questions.
