LibFramePool

About:

Creates a table containing n amount of frames of the same type with optional argument to predefine the frames. Since a table is being returned on creation, the created variable can be looped using a loop of your choice to make changes to the frames, or individual frames called upon based on their index position.

Usage:

local lib = LibStub("LibFramePool-1.0")

pool = lib:CreateFramePool(20, "CheckButton", {nil, parentFrame, "ChatConfigCheckButtonTemplate"})

lib:SetOnClickScript(pool, function() print("Hello world!") end)

Available functions:

CreateFramePool(numOfFrames, frameType[, frameArgs])
DeleteFramePool(Pool)
IncrementallyChangeXForAllFrames(Pool, point, initialOffsetX, incrementalOffsetX[, frames])
IncrementallyChangeYForAllFrames(Pool, point, initialOffsetY, incrementalOffsetY[, frames])
SetOnClickScript(Pool, script[, frames])
SetOnEventScript(Pool, script[, frames])
HideFrames(Pool[, frames])
ShowFrames(Pool[, frames])

Since the object returned by CreateFramePool is a table, it can also be iterated to run other WoW functions on them:

    for i = 1, #pool do
        if r == 3 then
            y = y - 20
            x = 8
            r = 0
        end
        pool[i].frame:SetPoint("TOPLEFT", x, y)
        x = x + 200
        r = r + 1
    end

The previous for loop will move the frames to look like this:

x x x
