  19. Subject: How to code a BusyPointer?
  20.  
  21. I'm just started with Amiga E V2.1b, and i have some questions.
  22.  
  23. Could someone give me some hints how to use the function SetPointer()
  24. (from the intuition.library), especially with the Array of data for
  25. the BusyPointer?
  26.  
  27. I'm trying to "port" (ahum :) the example on page 275 of the
  28. RKRM-Libraries, with the waitPointer, but i haven't succeeded yet.
  29.  
  30. In short, this is the important part of the C-code:
  31.  
  32. /* Start of Part */
  33. UWORD   __chip waitPointer[] = {
  34.         0x0000, 0x0000,         /* Reserved, must be NULL */
  35.         0x0400, 0x07c0, 0x0000, 0x07c0,
  36.         0x0100, 0x0380, 0x0000, 0x07e0,
  37.         0x07c0, 0x1ff8, 0x1ff0, 0x3fec,
  38.         0x3ff8, 0x7fde, 0x3ff8, 0x7fbe,
  39.         0x7ffc, 0xff7f, 0x7efc, 0xffff,
  40.         0x7ffc, 0xffff, 0x3ff8, 0x7ffe,
  41.         0x3ff8, 0x7ffe, 0x1ff0, 0x3ffc,
  42.         0x07c0, 0x1ff8, 0x0000, 0x07e0,
  43.         0x0000, 0x0000,         /* Reserved, must be NULL */
  44. };
  45.  
  46. void SetWaitPointer (struct Window *window)
  47. {
  48.     SetPointer(window, waitPointer, 16L, 16L, -6L, 0);
  49. }
  50.  
  51. void processWaiting (struct Window *window)
  52. {
  53.     Delay(100);
  54.     SetWaitPointer(window);     /* Call Busy-Pointer */
  55.     Delay(400);
  56.     ClearPointer(window);       /* Restore normal Pointer */
  57. }
  58.  
  59. void main(int argc, char **argv)
  60. {
  61.     struct Window *win;
  62.  
  63.     if (IntuitionBase = OpenLibrary("intuition.library", 37L)) {
  64.         if (win = OpenWindowTags(NULL,
  65.                             WA_Left,        20,
  66.                             WA_Top,         10,
  67.                             WA_Width,       300,
  68.                             WA_Height,      90,
  69.                             WA_MaxWidth,    ~0,
  70.                             WA_MaxHeight,   ~0,
  71.                             TAG_DONE) )
  72.         {
  73.             processWaiting(win);
  74.             CloseWindow(win);   /* Close this Window */
  75.         }
  76.         CloseLibrary(IntuitionBase);
  77.     }
  78. }
  79. /* End of Part */
  80.  
  81.  
  82. Any example(s)/hint(s) will be appreciated to make this a usable E-source!
  83.  
  84. Thanks in advance!
