How do I hook GameTooltip:OnTooltipSetItem ?

I want to add extra information to item stats shown in the tooltip. I just cant seem to get it to hook a function in that format. I'm not very experienced in lua :)

WoW Wiki: How To's

But I personally do:

Code:

local Orig_foo = foo

function foo(apple ,...)

  --Do stuff

  Orig_foo(apple ,...)

end

Or you could just add a line to the tooltip using

Code:

tooltip:AddDoubleLine(textLeft, textRight, textLeft.r, textLeft.g, textLeft.b, textRight.r, textRight.g, textRight.b);

Not quite Slakah, he wants to hook a script handler not a function...

Code:

local orig = GameTooltip:GetScript("OnTooltipSetItem")

GameTooltip:SetScript("OnTooltipSetItem", function(frame, ...)

        -- do crap



        --Call hook, if it exists

        -- It might not exist if nothing else was using this script handler!

        if orig then return orig(frame, ...) end

end)

Also Slakah, if you don't return the values passed back from your hook call at the end, you risk breaking the hook chain. Always pass all args forward and returns back in the chain!

It's like a bad chain letter - you need to keep passing it along!
