Editing WoW:API GetNumTalentTabs

{{wowapi}}
Returns the total number of tabs of talents one has.

 local numTabs = GetNumTalentTabs([inspect[,pet]]);

----
;''Arguments''

:;inspect : [[Boolean]] - If true returns the information for the inspected unit instead of the player. New with 2.3.

:;pet : [[Boolean]] - If true returns the information for the pet instead of the player. New with 2.3.

----
;''Returns''

:;numTabs : Integer - The number of tabs one has.

----
;''Example''

 local numTabs = GetNumTalentTabs()
 DEFAULT_CHAT_FRAME:AddMessage( numTabs )

;''Results'' : Displays the number of talents tabs one has.


;''Useful code: iteration over all talents''
 function talentpairs(inspect,pet)
   local tab,tal=1,0
   return function()
     tal=tal+1
     if tal>GetNumTalents(tab,inspect,pet) then
       tal=1
       tab=tab+1
     end
     if tab<=GetNumTalentTabs(inspect,pet) then
       return tab,tal
     end
   end
 end

Now,
 for tab,talent in talentpairs() do DEFAULT_CHAT_FRAME:AddMessage(tab..","..talent) end
- prints all player's tab-talent pairs from 1,1 through 3,20-something.

 for tab,talent in talentpairs(false,true) do DEFAULT_CHAT_FRAME:AddMessage(tab..","..talent) end
- prints all player's pet's tab-talent pairs; doesn't execute at all if the player has no pet.
 for tab,talent in talentpairs(true) do DEFAULT_CHAT_FRAME:AddMessage(tab..","..talent) end
- prints all inspected player's tab-talent pairs; doesn't execute at all if there is no inspected player.

----
;''Caveats''

There is a really annoying bug with this where it will sometimes return that there are 0 tabs.  Doing a reload of the User Interface appears to clear it up, but that's of limited utility.  Either avoid using this API, or include code to handle the case where it returns 0.

This has only happened to me at startup, if talents are checked before [[Events_P_(Party,_Petition,_Pet,_PlayerBank,_Player)#PLAYER_ALIVE|PLAYER_ALIVE]] fires. They may not be available to the API before that event. - [[User:Sine Pi|Sine Pi]] ([[User talk:Sine Pi|talk]]) 12:42, 28 July 2009 (UTC)

;Cataclysm

This API has been changed for Cataclysm:

 (unknown), TreeNameLocalized, TreeDescription, TreeIcon, PointsSpent, TreeNameUnlocalized , (unknown), (unknown) = GetTalentTabInfo(i)

For instance, as paladin you could get:

unknown A = 831 

TreeNameLocalized = Holy 

TreeDescription = Invokes the power of the Light to protect and to heal. 

TreeIcon = Interface\Icons\Spell_Holy_HolyBolt 

PointsSpent = 5 

TreeNameUnlocalized = PALADINHOLY 

unknown B = 0 

unknown C = true
