Editing WoW:API Frame HookScript

{{widgetmethod}}

Post hooks a script handler (secure).

 frame:HookScript("handler", function)

== Parameters ==
=== Arguments ===
<!-- List each argument, together with its type -->
:("handler", func)

:;handler : String - The handler to attach func to (OnShow, OnEvent, [[Widget_handlers|et al]])
:;func : Function - The function to call. Unlike [[API_Frame_SetScript|:SetScript()]], <tt>nil</tt> throws an error. <tt>func</tt> is called with arguments <tt>(frame, arg1, arg2, ...)</tt> (<tt>event</tt> being <tt>arg1</tt> for OnEvent handlers)

== Example ==
 for i = 1, 4 do
     local frame = _G["PartyMemberFrame"..i]
     frame:HookScript("OnClick", function(self, button)
         print(self:GetName() .. " clicked with " .. button)
     end)
 end

====Result====
Alert the player when he clicks a party member's portrait while preserving the security of the unit frame after calling its original handler.

== Notes ==
* Just like [[API_hooksecurefunc|hooksecurefunc]], this can be used on secure code.
* If the frame doesn't have a ''func'' for ''handler'', one will be created as if you called [[API_Frame_SetScript|:SetScript("handler", func)]].
* Every script handler has at least one argument (the frame itself, usually ''self''). See [[widget handlers]] for details on each handler.
