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) 
        return nRet; 
 
   } 
 
   else
