lua beginner question

[:1]greetings

i am quite new to develop own addons and the few tutorials that are out there let a few questions open. maybe you can help:

i am trying to create a simple tooltip when mouse hovers a frame. i already got:




Code:

function showtooltip()
 local testtip = CreateFrame("GameTooltip", "ToolTipName") -- Where do i need the ToolTipName for example? Is it even neccessary to declare?
 testtip:SetFrameStrata("TOOLTIP")
 testtip:SetClampedToScreen(true)
 testtip:SetOwner(f, "ANCHOR_CURSOR")
 testtip:SetText("tooltipText", 1, 1, 1)  -- Whats the difference between SetText and Addline?
 testtip:AddLine("tooltipText", 1, 1, 1) 
 testtip:Show()
end


f = CreateFrame("Frame",nil,UIParent)
f:SetFrameStrata("BACKGROUND")
f:SetWidth(500)
f:SetHeight(500)
f:SetScript("OnEnter", showtooltip)

t = f:CreateTexture(nil,"BACKGROUND")
t:SetTexture(1, 1, 1, 1)
t:SetAllPoints(f)
f.texture = t

f:SetPoint("CENTER",0,0)
f:Show()

the frame with the layer shows up ingame properly, but the tooltip hover isnt working. no error messages are shown.

thnx for your help,

You dont actually call the tooltip function, so it is never executed - bind it to a mouseover instead of OnEnter. You could test if the function is working by simply typing this in-game


Code:

 /script showtooltip()

SetText - changes the current text if the object already has a text area

AddLine - adds an additional line to a tooltip, this is probably the one you want.

You need to prefix your function, or declare it as local function.

't', 'f' and 'testtip' should also be prefixed, I wouldnt bother declaring these as locals until you have it working.|||Try :


Code:

f:EnableMouse(true)

before the "OnEnter" SetScript
