When, at some later time, the nested function is invoked, it - can access the variables that were created when the enclosing function was - invoked. This can perhaps best be illustrated through a small example: - - \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 70 - - The \c{counter()} function initializes a local variable to zero, - and returns a nested function. The nested function increments - the "outer" variable and returns its new value.
