Editing WoW:SecureHandlerStateTemplate

{{uitech}}
'''SecureHandlerStateTemplate''' is one of the SecureHandler templates introduced in [[Patch 3.0]]. Those templates exist in order to allow addon code to execute within a restricted environment, where it may perform protected actions but has access only to a limited subset of the API. SecureHandlerStateTemplate executes snippets whenever any attribute prefixed with "state-" changes value, making it ideal for use in combination with [[SecureStateDriver]].

== Snippets ==
The handler executes the following snippets in a restricted environment:
; _onstate-''identifier'' (self, stateid, newstate) : The snippet is executed when the "state-''identifier''" attribute changes value; ''identifier'' may be any arbitrary string of one or more characters.
:; self : Secure frame handle to the frame.
:; stateid : String - ''identifier'' of the changed state.
:; newstate : Mixed - new value of the "state-''identifier''" attribute. Note that if the value is not a string, boolean or a number, it'll be replaced with nil -- this a limitation enforced by the restricted environment.

== Example ==
The frame defined in XML below will be shown only if you have a hostile target. Note that the frame also behaves properly in combat, even though it is protected.
 <Frame name="MyStateFrame" inherits="SecureHandlerStateTemplate" parent="UIParent" protected="true">
  <Attributes>
    <Attribute name="_onstate-foo" value="if newstate == 'show' then self:Show(); else self:Hide(); end" />
  </Attributes>
  <Scripts>
   <OnLoad>
    SecureHandler_OnLoad(self); -- Our OnLoad handler overwrites this one, so execute it now.
    RegisterStateDriver(self, "foo", "[target=target,exists,harm] show; hide");
   </OnLoad>
  </Scripts>
