I've started porting some code from QScriptEngine to QJSEngine, but
there are some missing parts I don't know how to implement.
1) Here is the comparative "table":
- QScriptEngine --> QJSEngine
- QScriptValue --> QJSValue
- QScriptValueIterator --> QJSValueIterator
- QScriptContext --> ???
QScriptContext is the first big missing part. In the actual code is
used to retrive the name of an argument, like this:
static QScriptValue Envjs_runAsync(QScriptContext *ctx, QScriptEngine *eng)
{
QScriptValue fun = ctx->argument(0);
QtScriptFunctionInvoker *invoker = new QtScriptFunctionInvoker(fun, eng);
invoker->invokeLater();
return eng->undefinedValue();
}
There is not anything similar in QJSEngine as far as I know.
2) Some methods are using the throwError() method that return a
particular QScriptValue/QJSValue. I cannot simply create a new
QJSValue because I cannot pass the "Error" type to the constructor (I
can only verify if a QJSValue is an error with the isError() method.
Do you know where I can an overview of the changes needed in Qt5 when
we have to inject/evaluate/calling JavaScript code in Qt5? Are we
missing some methods?
p.s: if anyone is interested I'm trying to make EnvJs work like
explained here
http://labs.qt.nokia.com/2011/03/10/say-hello-to-envjs-for-qtscript/
but no success at the moment.
