DrgQueryDragitemPtr - Example Code

This example calls the DrgQueryDragitemPtr function to return a pointer to first DRAGITEM structure in the given DRAGINFO structure, after which it obtains the source window handle.

#define INCL_WINSTDDRAG /* Direct Manipulation (Drag) Functions  */
#include <os2.h>

PDRAGITEM  pDragitem;   /* DRAGITEM structure pointer            */
DRAGINFO   Draginfo;    /* DRAGINFO structure from which the     */
                        /* DRAGITEM structure is obtained        */
ULONG      ulIndex;     /* Zero-based index of the DRAGITEM      */
                        /* structure pointer to be returned      */
HWND       hwndSource;  /* Source window handle for the drag     */

USHORT     usn = 0;     /* Return pointer to first DRAGITEM      */

pDragitem = DrgQueryDragitemPtr(&Draginfo,usn);

hwndSource = pDragitem->hwndItem; /* Obtain source window handle */
