using controlMethodOverload() to overload formRun.closed()

Hi there

I try to capture a close command from a form outside the form itself. So I created a class and put code like this:

class foo

{

FormRun fr;

void bindForm(FormRun _formRun)

{

           fr = formRun;

           formRun.controlMethodOverload(true);

           formRun.controlMethodOverloadObject(this);

}

void formRun_close()

{

   /* ...

       do some extra code

   */

   fr.close();

}

}

However, the formRun_close method is never called, how do I have to name the method correctly?

formRun_close? (obviously not ...)

form_close?

this_close?

???_close?

Thank you for your Ideas
