Identifying buttons

[nightcracker]

Hey all!
For my new addon ncHoverBind, I need to find all actionbuttons and containerframe buttons.

I've solved the actionbutton problem pretty brutely with the following code(register is defined earlier):

local event = CreateFrame("FRAME")
event:RegisterEvent("PLAYER_ENTERING_WORLD")
event:SetScript("OnEvent", function()
	for key, val in pairs(_G) do
		if type(val)=="table" and val.GetAttribute and val.GetObjectType and val:GetObjectType()=="CheckButton" and val:GetAttribute("type")=="action" then
			register(val)
		end
	end
	event:UnregisterAllEvents()
end)

How can I loop _G for the containerframe buttons? Or better, give me a more efficient alternative!

local frame
for containerNum = 1, NUM_CONTAINER_FRAMES do
	for itemNum = 1, MAX_CONTAINER_ITEMS do
		frame = _G['ContainerFrame' .. containerNum .. 'Item' .. itemNum]
	end
end

You can really clean that up using EnumerateFrames, which is like a "next" function for frames. Slap the following code in somewhere after you have defined your "register" function. Every time an addon is loaded it will look at only those frames that were created since the last time it was run.

do
	local lastFrame

	local function ScanUnseenFrames()
		local frame = EnumerateFrames(lastFrame)
		while frame do
			if frame:GetObjectType() == 'CheckButton' and frame:GetAttribute('type') == 'action' then
				register(frame)
			end
			lastFrame, frame = frame, EnumerateFrames(frame)
		end
	end
	ScanUnseenFrames()

	lastFrame = CreateFrame('Frame')
	lastFrame:SetScript('OnEvent', ScanUnseenFrames)
	lastFrame:RegisterEvent('ADDON_LOADED')
	lastFrame:Hide()
end
