Hello.
I would like to change the width of each class icon when the max number of the resource changes.

local ClassIconsPostUpdate = function(element, cur, max, maxchange)
    for i = 1, 5 do
        if cur == max then
            element[i]:SetStatusBarColor(unpack(classicon_colors[cur]))
        else
            element[i]:SetStatusBarColor(unpack(classicon_colors[i]))
        end
        if maxchange then
            element[i]:SetWidth((oUF_MlightDB.width+3)/max-3)
        end     
    end
end

local _, class = UnitClass("player")
        
        -- Runes, Shards, HolyPower and so on --
        if multicheck(class, "DEATHKNIGHT", "WARLOCK", "PALADIN", "MONK", "SHAMAN", "PRIEST", "MAGE", "ROGUE", "DRUID") then
            local count
            if class == "DEATHKNIGHT" then 
                count = 6
            elseif class == "WARLOCK" then
                count = 4
            elseif class == "PALADIN" or class == "PRIEST" or class == "MONK" then
                count = 5
            elseif class == "SHAMAN" then
                count = 4
            elseif class == "MAGE" then
                count = 6
            elseif class == "ROGUE" or class == "DRUID" then
                count = 5 -- combopoints
            end
 
            local bars = CreateFrame("Frame", nil, self)
            bars:SetPoint("BOTTOMLEFT", self, "TOPLEFT", 0, 3)
            bars:SetSize(oUF_MlightDB.width, 10)
 
            for i = 1, count do
                bars[i] = createStatusbar(bars, texture, nil, oUF_MlightDB.height*-(oUF_MlightDB.hpheight-1), (oUF_MlightDB.width+2)/count-3, 1, 1, 1, 1)
 
                if i == 1 then
                    bars[i]:SetPoint("BOTTOMLEFT", bars, "BOTTOMLEFT")
                else
                    bars[i]:SetPoint("LEFT", bars[i-1], "RIGHT", 3, 0)
                end
 
                bars[i].bd = createBackdrop(bars[i], bars[i], 1)
            end
 
            if class == "DEATHKNIGHT" then
                self.Runes = bars
            elseif class == "WARLOCK" then
                self.WarlockSpecBars = bars
            elseif class == "PALADIN" or class == "PRIEST" or class == "MONK" then
                self.ClassIcons = bars
                self.ClassIcons.UpdateTexture = function() end
                self.ClassIcons.PostUpdate = ClassIconsPostUpdate
            elseif class == "SHAMAN" then
                self.TotemBar = bars
            elseif class == "MAGE" then
                self.ArcaneCharge = bars
            elseif class == "ROGUE" or class == "DRUID" then
                self.CPoints = bars
                self.CPoints.PostUpdate = CpointsPostUpdate
            end
        end

When the max number of power changes, it works properly. But there's a problem when log-in.
If the player is shadow priest. The width of each element is 1/5 of the width of player frame.
I would like it to be 1/3. A paladin under lvl 85 ,a warlock with 3 soul shards and a monk with 4 chis got the same problem.
The solution I found is to change element.__max to 5 in oUF\elements\classicons.lua(because I can't find a right place to make it in my layout).
This means: when I create the frames/textures for the element, I set the width of each icon suppose the player got 5 class icons. When PLAYER_TALENT_UPDATE fires, oUF update the element and oldMax ~= max is true in element:PostUpdate(cur, max, oldMax ~= max). So the layout can change the width of each icon when log-in.

Haste, I really appreciate if you could set element.__max to 5 in oUF\elements\classicons.lua or make it easier to change element.__max in layout.
