remove docs that mention QScriptValue::{scope,setScope}()
Those functions are internal and we don't want to support them
in the JSC back-end, because they expose too much implementation
detail of the old back-end.

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. The variable - persists over function calls, as shown in the following example: - - \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 71 - - The \c{counter()} function can be implemented as a native function, too - \mdash or rather, as a pair of native functions: One for the outer and - one for the inner. The definition of the outer function is as follows: - - \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 72 - - The function creates a local variable and initializes it to zero. - Then it wraps the inner native function, and sets the scope of - the resulting function object to be the activation object associated - with this (the outer) function call. The inner function accesses - the "outer" activation through the scope of the callee: - - \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 73 - - It is also possible to have a hybrid approach, where the outer function - is a native function and the inner function is defined by a script: - - \snippet doc/src/snippets/code/doc_src_qtscript.qdoc 74 - \section2 Property Getters and Setters A script object property can be defined in terms of a getter/setter |
