Returns the value of a specific attribute (or an attribute matching the prefix/suffix arguments).

value = frame:GetAttribute(name);
value = frame:GetAttribute(prefix, name, suffix);

ArgumentsEdit

prefix 
String - modifier prefix string: a concatenation of alt-, ctrl-, and shift-, whichever apply, in that order.
name 
Attribute name. If passed as the only argument, this may be a fully qualified value; otherwise, it is the unmodified name of the attribute being retrieved.
suffix 
String - button suffix string: either a numeric string or a dash followed by an arbitrary button name.

Returns Edit

value 
Mixed - the value of the matching attribute; nil if no attribute matched the arguments.

Matching order Edit

When invoked with three arguments, this function attempts to return attributes in the following order (returning the first attribute that exists):

  1. prefix .. name .. suffix
  2. "*" .. name .. suffix
  3. prefix .. name .. "*"
  4. "*" .. name .. "*"
  5. name
