Query talents from other players in classic (using the Details protocol)
Loosely based on LibTalentQuery,
but uses addon messages instead of NotifyInspect()
local TalentQuery = LibStub:GetLibrary("LibClassicTalentQuery")
TalentQuery.RegisterCallback(MyAddon, "TalentQuery_Update")
TalentQuery:Query(unitOrGuid)
-- Update will fire for any query result, and also for any PARTY broadcasts made
-- by the Details addon.
function MyAddon:TalentQuery_Update(e, name, server, talents)
-- ...
end
