Hi,

Can anybody please explain why the following keeps adding rows to my table view :

Qt Code: 
  1. void DAStaticModel::setCanData( int nAmount )
  2. {
  3. 	if( nAmount <= 0 )
  4. 		return;
  5.  
  6. 	beginInsertRows(QModelIndex(), 0, 0 );  
  7. 	endInsertRows();
  8.  
  9. }
  10.  
  11. QVariant DAStaticModel::data( const QModelIndex& index, int role) const
  12. {
  13. 	QVariant data;
  14.  
  15. 	if (!index.isValid())
  16. 		return QVariant();
  17.  
  18. 	if(index.column() > 3 )
  19. 	{
  20. 		return QVariant();
  21. 	}
  22.  
  23. 	if( role == Qt::DisplayRole )
  24. 	{
  25.  
  26. 		QString strId = "";
  27. 		static QMapIterator<QString, QObject*>i(*theApp->GetCanMap());
  28. 		static CanMessages* pMess = NULL;
  29. 		if( i.hasNext() && index.column() == 0 ) 
  30. 		{
  31. 			i.next();
  32. 			pMess = (CanMessages*)i.value();
  33. 			strId = i.key();
  34. 		}
  35. 		else 
  36. 			if( !i.hasNext() )  // need to reset to begining of the list
  37. 			{
  38. 				i.toFront();
  39. 			}
  40.  
  41. 		switch( index.column() )
  42. 		{
  43. 		case 0:			
  44. 			data = strId;
  45. 			break;
  46. 		case 2:
  47. 			{
  48. 				if( pMess )
  49. 				{
  50. 					data = pMess->m_strData;
  51. 				}
  52. 			}
  53. 			break;
  54. 		case 1:
  55. 			{
  56. 				if( pMess )
  57. 				{
  58. 					data = pMess->m_strTime;
  59. 				}
  60. 			}
  61. 			break;
  62. 		case 3:
  63. 			{
  64. 				if( pMess )
  65. 				{
  66. 					QString strCount;
  67. 					strCount.sprintf( "%d", pMess->m_nCount );
  68. 					data = strCount;
  69. 				}
  70. 			}
  71. 			break;
  72. 		}
  73. 	}
  74.  
  75. 	return data;
  76. }
  77.  
  78. int DAStaticModel::rowCount( const QModelIndex& parent ) const
  79. {
  80. 	return 	theApp->GetCanMap()->size();
  81. }
To copy to clipboard, switch view to plain text mode 

If I don't call the beginInsertRows / endInsertRows nothing is displayed in my table view.

Please note that the rowCount is always one...

Thanks,
Steve
