My problem is my object of thread inside classA and object of classA
inside function myGUIFunctionNamed_Execute().I want
myGUIFunctionNamed_Execute()
return immediately after i called it,but i dont no how to delete
object(objectA)

If the object is automatic, rather than dynamic, you won't have this
problem.

You still have an issue with the lifetime of the object and the thread.
It generally isn't a good idea to delete an object that contains a
thread, assuming the thread uses the object's data, while the thread is
running.
