Cannot get spell id from tooltip generated by metashowtooltip

[fatrog]

Hello,

I'm facing a problem while trying to get spellid from tooltips. When I try to get it from a macro tooltip, it returns nil

Here is my code

_G["GameTooltip"]:HookScript("onShow",function(self)
    
    local spellName, spellID = self:GetSpell()
    print(spellID)
end)

The macro have a metashowtooltip (#showtooltip) instruction and the spell is well shown in the (what I thought was) the global tooltip.

Thanks for your help

EDIT: mounts return nil too. neither spells or items methods work

I got myself through it

here's how I did it

_G["GameTooltip"]:HookScript("onShow",function(this)

    local cooldownMS, gcdMS, spellName
    local spellName, spellID = this:GetSpell()
    local itemName, ItemLink = this:GetItem()
    if spellID ~= nil then
       cooldownMS, gcdMS = GetSpellBaseCooldown(spellID)
       print("ID:"..gcdMS)
    elseif itemName ~= nil then
       spellName, spellID = GetItemSpell(ItemLink)
       cooldownMS, gcdMS = GetSpellBaseCooldown(spellID)
       print("spell from item link:"..gcdMS)
    else
       spellName = _G[this:GetName().."TextLeft"..1]:GetText()
       _,_,_,_,_,_,spellID = GetSpellInfo(spellName)
       cooldownMS, gcdMS = GetSpellBaseCooldown(spellID)
       print("spell with no ID:"..gcdMS)
    end
end)
