4310 :: How to use destructor in nim ?

  Hi all, I am trying this piece of code

  proc `=destroy`*(x : var CustomButtonClass) =
      RemoveWindowSubclass(x.handle, Btn_WndProc, 1)
  Run

  All i want to remove the subclassing when CustomButtonClass destroyed. But the compiler says that "signature for '=destroy' must be procT: object" I am confused. An example will be enough for me to understand the concept. Thanks in advance.

  Well your CustomButtonClass must be an object.

  Aearq, Then it must not be a ref object. Am i right ?

  Oh, I see. My CustomButtonClass is a ref object. You mean to destroy it, it must be an object. Not ref
