ScrollFrames make me sad :(

[hairy_palms]

so ideally i wanted to make a scroll frame for a regular frame, i thought by reading the API it should work like this

local Parentpanel = CreateFrame("Frame", "Parentpanel", UIParent)
Parentpanel:SetPoint('CENTER', UIParent, 'CENTER', 0, 1)
Parentpanel:SetWidth(288)
Parentpanel:SetHeight(288)
for i = 1, 30 do
	local name, title, notes, enabled, loadable, reason, security = GetAddOnInfo(i)
	Parentpanel:CreateFontString("Childlist"..i, 'OVERLAY')
	_G["Childlist"..i]:SetPoint('TOPLEFT', Addonpanel, 'TOPLEFT', 10, -28*i)
	_G["Childlist"..i]:SetFont("Fonts\\ARIALN.ttf", 12)
	_G["Childlist"..i]:SetWidth(236)
	_G["Childlist"..i]:SetHeight(28)
	_G["Childlist"..i]:SetJustifyH('LEFT')
	_G["Childlist"..i]:SetText(title)		
end
local scrollArea = CreateFrame("ScrollFrame", "Scroller", UIParent, "UIPanelScrollFrameTemplate")
scrollArea:SetPoint("TOPLEFT", Parentpanel, "TOPLEFT", 8, -30)
scrollArea:SetPoint("BOTTOMRIGHT", Parentpanel, "BOTTOMRIGHT", -30, 8)
scrollArea:SetScrollChild(Parentpanel)

i was expecting it to create a scrollbar to scroll through the list of fontstrings,
any idea where ive gone wrong?

Hrm. First of all, what is Addonpanel? You should anchor your fontstrings to the scrollframe child (Parentpanel in your case). Also, any reason for a 10 pixel x-offset?
I'd use it somewhat like this:

-- create the scroll frame
local scrollArea = CreateFrame("ScrollFrame", "Scroller", UIParent, "UIPanelScrollFrameTemplate")
scrollArea:SetPoint("TOPLEFT", Parentpanel, "TOPLEFT", 8, -30)
scrollArea:SetPoint("BOTTOMRIGHT", Parentpanel, "BOTTOMRIGHT", -30, 8)

-- create the scroll frame content
local Parentpanel = CreateFrame("Frame", "Parentpanel", scrollArea) -- don't know if you need to anchor it this way, but it works for me
scrollArea:SetScrollChild(Parentpanel)
Parentpanel:SetPoint("CENTER", UIParent, "CENTER", 0, 1)
Parentpanel:SetWidth(288)
Parentpanel:SetHeight(288)
for i = 1, 30 do
    local name, title, notes, enabled, loadable, reason, security = GetAddOnInfo(i)
    local addonText = Parentpanel:CreateFontString("Childlist"..i, 'OVERLAY')
    if i == 1 then
        addonText:SetPoint("TOPLEFT", Parentpanel)  -- anchors the first string, parent should be the content frame
    else
        addonText:SetPoint("TOPLEFT", _G["Childlist"..i-1], "BOTTOMLEFT")   -- anchors any following fontstrings below the previous one
    end
    addonText:SetFont("Fonts\\ARIALN.ttf", 12)
    addonText:SetWidth(236)
    addonText:SetHeight(28)
    addonText:SetJustifyH("LEFT")
    addonText:SetText(title)		
end

No guarantees and probably not the prettiest solution ... but I hope it helps
