application paused

Hi to everybody!

I have a question. I make a simple application:

Code:

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
 
    QStringList numbers;
    numbers << "One" << "Two" << "Three" << "Four" << "Five";
    QAbstractItemModel *model = new QStringListModel(numbers);
    QListView *view = new QListView();
    view->setModel(model);
    view->show();
 
    uchar char1 = (uchar)1;
    uchar char2 = (uchar)244;
 
    //int x = (int)char1<<8 | char2;
    int x = 1024;
    uchar z = (uchar)(x>>8);
    uchar p = (uchar)x;
    qDebug() << "primo byte" << z;
    qDebug() << "secondo byte" << p;
 
 
    return a.exec();
}

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!
