QSA 1.2.1 && MessageBox

[xk]

I have this code:

QApplication app(argc, argv);
 
  QString fileName = "test-script.qs";
  QFile file(fileName);
  if(file.open(QIODevice::ReadOnly) == 0)
    return 1;
 
  QString scriptCode(file.readAll());
 
  CReport *report = new CReport;
  CReportWrapper *reportWrapper = new CReportWrapper(report);
  reportWrapper->setObjectName("reportWrapper1");
 
  QSInterpreter ip;
  ip.addWrapperFactory(new CWrappers());
  ip.addTransientObject(reportWrapper);
  ip.evaluate(scriptCode, 0, fileName);
  ip.call("mytest");

QApplication app(argc, argv);

  QString fileName = "test-script.qs";
  QFile file(fileName);
  if(file.open(QIODevice::ReadOnly) == 0)
    return 1;

  QString scriptCode(file.readAll());

  CReport *report = new CReport;
  CReportWrapper *reportWrapper = new CReportWrapper(report);
  reportWrapper->setObjectName("reportWrapper1");

  QSInterpreter ip;
  ip.addWrapperFactory(new CWrappers());
  ip.addTransientObject(reportWrapper);
  ip.evaluate(scriptCode, 0, fileName);
  ip.call("mytest");

To copy to clipboard, switch view to plain text mode 

and test-script.qs consist of:

function mytest()
{
  MessageBox.warning("This is test", MessageBox.Yes, MessageBox.No);
  Application.reportWrapper1.setPing(666);
}

function mytest()
{
  MessageBox.warning("This is test", MessageBox.Yes, MessageBox.No);
  Application.reportWrapper1.setPing(666);
}

To copy to clipboard, switch view to plain text mode 

And i have error message: "Error. Use of undefined variable 'MessageBox'"
