Checking for and hooking scripts?

[ChaosInc]

Took a stab in the dark and failed miserably. So here I am again.

for k,_ in pairs(activeProfile) do
				if _G[k].OnShow ~= nil then
					print("Debug: ".. k.. ".OnShow found!")
					origOnShow = _G[k].OnShow
					_G[k].OnShow = CFM_ShowHook
				end
				CFM_ApplySettings(k)
			end

I haven't the foggiest on how to accomplish this. To elaborate, I'm trying to do a check if a frame has an OnShow script, and if so, hook into it with my function. Reason I want to do this is because users trying to modify LoD frames (such as the vehicle bar, I like to shrink mine personally) won't see any changes when the frame actually shows up unless they go in and do a quick setting change while the frame is visible.

Script handlers are not stored inside the object, but you can use frame:GetScript("OnShow") to get the function. There's also the function frame:HookScript(script, func) which does exactly the same as hooksecurefunc only for scripts.
If you want to overwrite the old script-function instead of just hooking in it after, you can use SetScript of course

I wrote a simple function for some of my addons which use HookScript or SetScript based on whether the frame already has a script, maybe you'll find it useful

local function hookScript(self, script, func)
	if(self:GetScript(script)) then
		self:HookScript(script, func)
	else
		self:SetScript(script, func)
	end
end

Thanks mate. Exactly what I needed.
