Hi,

I am including the code below.
Plz state why this happens?

Qt Code: 
  1. FullCode::FullCode()
  2.     : QWidget( 0, 0 )
  3. {
  4.  
  5.     QGridLayout * g = new QGridLayout( this, 2, 2, 0);
  6.         ............................
  7.  
  8.     l = new QListBox( this );
  9.     g->addWidget( l, 1, 1 );
  10.     l->setMaximumSize(125,115);
  11.     l->insertItem("M",-1);
  12.     l->insertItem("Ma",-1);
  13.  
  14.     ............................
  15. }
  16.  
  17.  
  18. FullCode::~FullCode()
  19. {
  20.     delete bg;
  21. }
  22.  
  23.  
  24. void FullCode::keyPressEvent(QKeyEvent *event)
  25. {
  26. 	printf("Key Press.... %d\n", event->key());
  27. 	if(event->key() == Qt::Key_Up) 
  28. 	{
  29.         	key_press = -1;
  30.         }
  31.         else if(event->key() == Qt::Key_Down) 
  32. 	{
  33. 		key_press = 1;
  34.         }
  35. 	else if(event->key() == Qt::Key_Right)
  36.         {
  37.                 key_press = 2;
  38.         }
  39. 	else if(event->key() == Qt::Key_Left)
  40.         {
  41.                 key_press = -2;
  42.         }
  43.         else if(event->key() == Qt::Key_Return) 
  44. 	{	
  45. 		key_press = 3;
  46. 	}
  47. 	else {
  48. 		key_press = 0;
  49. 	}
  50. }
  51.  
  52. void QListBox::keyPressEvent(QKeyEvent *event)
  53. {
  54. 	FullCode ff;	
  55. 	ff.keyPressEvent(event);
  56. }
