Hello everybody

i'm aiming for the following ecma scenario:
Qt Code: 
  1. var whatever = new myClass();
  2. whatever.whatreallyever();
To copy to clipboard, switch view to plain text mode 

So i want to use a custom c++, from QObject inherited class from within QtScript.

... after hours of consulting the documentation, forum threads and tried tons of experiments by myself - i still wasn't able to make any object available to a QScriptEngine like shown in the case above.

So my question is, how can you implement some newable c++ object for QtScript and/or is there any minimal example for that case?

What i've tried so far:
1) Qt 4.8's customClass Example - doesnt compile under Qt5.3, mocking that
Qt Code: 
  1. ByteArrayClass *cls = qscriptvalue_cast<ByteArrayClass*>(ctx->callee().data());

2) Experiment 1:
Qt Code: 
  1. qScriptRegisterQObjectMetaType<myObject*>(&engine);
  2. QScriptValue myObjectClass = engine.scriptValueFromQMetaObject<myObject>();
  3. engine.globalObject().setProperty("myObject", myObjectClass);
  4.  
  5. QScriptValue result = engine.evaluate("var obj = new myObject();");
  6. // (program crashes according to GDB at (??))

3) Experiment 2:
Qt Code: 
  1. QScriptEngine engine;
  2. myCLassPrototype myProto;
  3. engine.setDefaultPrototype(qMetaTypeId<myClassMaster*>(),
  4.                              engine.newQObject(&myProto));
  5. engine.evaluate("var x = new myClassProto()");
  6. // or engine.evaluate("var x = new myClassMaster()");
  7. // (resulting in "ReferenceError: Can't find variable: shitCLassPrototype")

4) Experiment 3:
Qt Code: 
  1. class Wrapper_QMessageBox: public QMessageBox, protected QScriptable
  2. {
  3.  Q_OBJECT
  4.  public:
  5.  
  6.  Wrapper_QMessageBox(QWidget *parent =0)
  7.  : QMessageBox(parent) {}
  8.  
  9.  Wrapper_QMessageBox(Icon icon, const QString & title, const QString & text, StandardButtons buttons = NoButton, QWidget * parent = 0, Qt::WindowFlags f = Qt::Dialog | Qt::MSWindowsFixedSizeDialogHint)
  10.  : QMessageBox(icon,title,text,buttons,parent,f) {}
  11.  
  12.  public slots:
  13.   QScriptValue qscript_call(QWidget *parent = 0)
  14.   {
  15.    QMessageBox * const iface = new Wrapper_QMessageBox(parent);
  16.    return engine()->newQObject(iface, QScriptEngine::AutoOwnership);
  17.   }
  18.   QScriptValue qscript_call( Icon icon, const QString & title, const QString & text, StandardButtons buttons = NoButton, QWidget * parent = 0, Qt::WindowFlags f = Qt::Dialog | Qt::MSWindowsFixedSizeDialogHint )
  19.   {

  21.    return engine()->newQObject(iface, QScriptEngine::AutoOwnership);
  22.   }
  23.   void setWindowTitle ( const QString & title )

  28.  
  29. engine.globalObject().setProperty("QMessageBox", engine.newQObject(new Wrapper_QMessageBox, QScriptEngine::AutoOwnership));
  30. QScriptValue result = engine.evaluate("var x = new QMessageBox();");
  31. // (resulting in "error: TypeError: Result of expression 'QMessageBox' [Wrapper_QMessageBox(name = "")] is not a constructor.<global>() at 1")

Also, whenever i've tried to use:
Qt Code: 
  1. Q_SCRIPT_DECLARE_QMETAOBJECT(myObject, QObject*);
To copy to clipboard, switch view to plain text mode 
or
Qt Code: 
  1. Q_DECLARE_METATYPE(myObject);
To copy to clipboard, switch view to plain text mode 

gcc yells at me that:

Besides: where are all the QtScript examples in the Qt 5.3 SDK (QtCreator doesn't show any - only QML examples when searching for "script")?
