wpDeleteFromObjUseList - Example Code

In this example, when the last view of a MYFOLDER object is closed, we zero out its first view instance variable, so that the next time it has a first view opened, we can keep track of that.

SOM_Scope BOOL  SOMLINK myfold_wpDeleteFromObjUseList(MYFOLDER *somSelf,
                       PUSEITEM  pUseItem )
{
   MYFOLDERData *somThis   = MYFOLDERGetData(somSelf);
   PUSEITEM      pItem;
   BOOL          rcParentCall;
   MYFOLDERMethodDebug("MYFOLDER","myfold_wpDeleteFromObjUseList");

          /* Call parent's method first */

   rcParentCall = parent_wpDeleteFromObjUseList(somSelf, pUseItem);

   pItem = _wpFindUseItem(somSelf, USAGE_OPENVIEW, NULL);

   if (!pItem) {

      _setFirstViewHandle(somSelf, NULLHANDLE);

   } /* endif */

   return( rcParentCall );
}
