Alright. But where should I be putting that hooksecurefunc? I've tried adding it to the SkinGrid addon but can't get it to work.

Here's how the code looks now, but it doesn't do anything since I don't have anything in the Grid_AddBorder funcion. If you could point out where to add it that would be awesome

local function SkinGrid()
    local GridFrame = Grid and Grid:GetModule("GridFrame")
    if GridFrame and GridFrame.registeredFrames then
        -- print("Adding borders to Grid frames")
 
        local function Grid_AddBorder(f)
            
        end
 
        local o = GridFrame.RegisterFrame
        GridFrame.RegisterFrame = function(self, f)
            o(self, f)
            Grid_AddBorder(f)
        end
 
        return true
    end
end
 
if not SkinGrid() then
    local f = CreateFrame("Frame")
    f:RegisterEvent("ADDON_LOADED")
    f:RegisterEvent("PLAYER_LOGIN")
    f:SetScript("OnEvent", function()
        if SkinGrid() then
            f:UnregisterAllEvents()
            f:SetScript("OnEvent", nil)
            SkinGrid = nil
        end
    end)
end
