Example

This example shows how to edit a container object this example assumes that the container limits would be at least { 10, 10, 300, 200 }.

L_INT LContainer_EditObjectExample(LContainer* pLContainer)  
{ 
   L_INT nRet; 
 
   nRet = pLContainer ->IsValid (); 
 
   if ( nRet == SUCCESS) /* check the validity of container handle */ 
 
   { 
 
      CONTAINEROBJECTDATA   Data ; 
 
      CONTAINERPOLYLINEDATA   PolyData ; 
 
      VECTORPOINT pt [ 7 ] ; 
 
      /* Set the Polyline points to some random numbers */ 
 
      pt[0].x = 10 ;   pt[0].y = 10 ;  
 
      pt[1].x = 80 ;   pt[1].y = 20 ; 
 
      pt[2].x = 100 ; pt[2].y = 60 ;  
 
      pt[3].x = 10 ;   pt[3].y = 40 ;  
 
      pt[4].x = 100 ; pt[4].y = 200 ; 
 
      pt[5].x = 200 ; pt[5].y = 100 ; 
 
      pt[6].x = 300 ; pt[6].y = 200 ; 
 
      /* Set the container object data */ 
 
      Data.nSize  = sizeof ( CONTAINEROBJECTDATA ) ;  
 
      Data.nObjectType = CONTAINER_OBJECT_TYPE_POLYLINE ;

      /* Click right-mouse button to abort editing */ 
 
      nRet = pLContainer ->EditObject ( &Data );
