Hi to everybody!

I have a question. I make a simple application:
Qt Code: 
  1. int main(int argc, char *argv[])
  2. {
  3.     QApplication a(argc, argv);
  4.  
  5.     QStringList numbers;
  6.     numbers << "One" << "Two" << "Three" << "Four" << "Five";
  7.     QAbstractItemModel *model = new QStringListModel(numbers);
  8.     QListView *view = new QListView();
  9.     view->setModel(model);
  10.     view->show();
  11.  
  12.     uchar char1 = (uchar)1;
  13.     uchar char2 = (uchar)244;
  14.  
  15.     //int x = (int)char1<<8 | char2;
  16.     int x = 1024;
  17.     uchar z = (uchar)(x>>8);
  18.     uchar p = (uchar)x;
  19.     qDebug() << "primo byte" << z;
  20.     qDebug() << "secondo byte" << p;
  21.  
  22.  
  23.     return a.exec();
  24. }
To copy to clipboard, switch view to plain text mode 

when i do debugging my application pause in
C:\Qt\ ..\4.7.0\src\corelib\kernel\qeventdispatcher_win.c pp at line 827

How can resolve?

Thanks!
