Detailed Description

Use this class for manageing p->num_additional_widgets by widget names
Example:

typedef struct // (todo: define your data structure here)
{
  pvWidgetIdManager mgr;
}
DATA;

static int slotInit(PARAM *p, DATA *d)
{
  if(p == NULL || d == NULL) return -1;
  int id;

  d->mgr.init(p,ID_END_OF_WIDGETS);

  id = d->mgr.newId("test1");
  pvQPushButton(p,id,0);
  pvSetGeometry(p,id,270,40,100,30);
  pvSetText(p,id,"test1");
  pvShow(p,id);

  return 0;
}                                                      }

static int slotButtonPressedEvent(PARAM *p, int id, DATA *d)
{
  if(p == NULL || id == 0 || d == NULL) return -1;
  if(id == obj1)
  {
    printf("knowns id's:\n");
    int i = d->mgr.first();
    while(i > 0)
    {
      printf("name=%s id=%d\n", d->mgr.name(i),i);
      i = d->mgr.next();
    }
  }
  return 0;
}
