Example Code

This example destroys a bit-map pointer, created by either WinCreatePointer or WinCreatePointerIndirect, once the window has received a close message (WM_CLOSE).

#define INCL_WINPOINTERS        /* Window Pointer Functions     */
#define INCL_GPIBITMAPS         /* Graphics Bit-map Functions    */
#include <os2.h>
#define IDP_BITMAP 1

HPS   hps;              /* presentation-space handle            */
HWND  hwnd;             /* window handle                        */
HPOINTER  hptr;         /* bit-map pointer handle               */
HBITMAP  hbm;           /* bit-map handle                       */
BOOL  fSuccess;         /* success indicator                    */

case WM_CREATE:
     hps = WinBeginPaint(hwnd, NULLHANDLE, NULL);
     hbm = GpiLoadBitmap(hps, 0L, IDP_BITMAP, 64L, 64L);
     WinEndPaint(hps);

     hptr = WinCreatePointer(HWND_DESKTOP, hbm,
                             TRUE, /* use true (system) pointer */
                             0, 0); /* hot spot offset (0,0)    */


case WM_CLOSE:
     fSuccess = WinDestroyPointer(hptr);
