wpFreeIconPosData - Example Code

This example shows how you can use the wpInitIconPosData, wpIdentify, wpQueryIconPosition, and wpFreeIconPosData methods to find the icon position information for all objects within a folder. In this example, somSelf contains the pointer to the folder being examined.

    BOOL        bSem;
    WPObject    *Object;
    CHAR        szIdentity[CCHMAXSTRING];
    POINTL      ptl;
    ULONG       ulIndex;

    /* Retrieve the icon position information for all objects within the
     * folder */
    _wpInitIconPosData(somSelf);

    /* Find the every object within the folder   */
    bSem = !_wpRequestObjectMutexSem(somSelf,SEM_INDEFINITE_WAIT);
    for (Object = _wpQueryContent(somSelf,NULL,QC_FIRST);
         Object;
         Object = _wpQueryContent(somSelf,Object,QC_NEXT));
    {

       /* For each object in the folder, find the position of its icon
        * in an Icon View of the folder  */
       if (_wpIdentify(Object,szIdentity))
       {
          if (_wpQueryIconPosition(somSelf,szIdentity,&ptl,&ulIndex))
          {
             /***** ptl contains the position of the icon for this object *****/
          }
       }
    }
    if (bSem)
    {
       _wpReleaseObjectMutexSem(somSelf);
    }

    /* Free the icon position data structure   */
    _wpFreeIconPosData(somSelf);
