Qt4: Create Qt object instance from qt script

There is a simple way to create QT object instances from qt script.
For instance, let's create a QDialog from qs.

• Declares the given QMetaObject:

  Q_SCRIPT_DECLARE_QMETAOBJECT(QDialog, QWidget*)



• Creates a QScriptValue that represents the Qt class

  QScriptValue dialogClass = engine.scriptValueFromQMetaObject<QDialog>();
  engine.globalObject().setProperty("QDialog", dialogClass);



• code.qs is:

  var d = new QDialog();
  d.windowTitle = "qs dialod"
  d.show()



• run scriplet from qt/c++:

  QFile file("code.qs");
  file.open(QIODevice::ReadOnly);
  engine.evaluate(file.readAll());
  file.close();
