Example

This example shows the minimum requirements to start using some container.

L_INT LContainer_CreateExample( HWND hWnd, LContainer & lcont)
{
   L_INT nRet;
   CONTAINERMETRICS Metrics ;
   /* Initiate the container handle */
   nRet = lcont.Initialize () ; 
   if(nRet != SUCCESS)
      return nRet;
   /* Create the container and attach it to its owner window */
   nRet = lcont.Create ( hWnd ) ;
   if(nRet != SUCCESS)
      return nRet;
   nRet = lcont.IsValid ();
   if ( nRet == SUCCESS ) /* the validity of the container handle */
   {
      /* Set the container object type to rectangle */
      nRet = lcont.SetObjectType (CONTAINER_OBJECT_TYPE_RECT ) ;
      if(nRet != SUCCESS)
         return nRet;
      /* Initiate the container metrics */
      Metrics.nSize        = sizeof ( CONTAINERMETRICS ) ;
      Metrics.dwMask  = CMF_LIMITS ; 
      /* Set the container limits to some value, all container inputs (after scaling ) will be restricted  to this range */
      SetRect ( &Metrics.rcLimits, 0, 0, 500, 500 ) ;
      /* Set the container metrics */
     nRet = lcont.SetMetrics ( &Metrics ) ;
     if(nRet != SUCCESS)
