How to use TagItem in TDR_EasyStruct (TimedDosRequesterTags() function)?
Hi, just tried to use TimedDosRequesterTags() and change its 'EasyStruct' using TDR_EasyStruct, as I want the requeter to opne centered on a ReAction GUI window I'm developing. Seems I'm (as usual) missing something, 'cos it always pops up centered on screen. Are the TagItem I set ok? BTW pwindow is a 'struct Window' defined globally on source. 
  1. uint32 DoMessage(char *message, char reqtype, STRPTR buttons)
  2. {
  3.  int32 nDummy;
  4.  struct TagItem es_ti[] = { {ESA_Position, REQPOS_CENTERWINDOW}, {TAG_DONE, 0} };
  5.  struct EasyStruct es;// = {sizeof(struct EasyStruct),
  6.                       //   ESF_TAGGED,
  7.                       //   "DefMousePointers", NULL, NULL,
  8.                       //   NULL, es_ti
  9.                       //  };
  10. 	es.es_StructSize = sizeof(struct EasyStruct);
  11. 	es.es_Flags = ESF_TAGGED;
  12. 	es.es_Title = "DefMousePointers";
  13. 	es.es_TagList = es_ti;
  14.  
  15.  
  16.  nDummy = IDOS->TimedDosRequesterTags(//TDR_TitleString,  "DefMousePointers",
  17.                                       TDR_GadgetString, buttons? buttons : GetString(&li,MSG_OK_GAD),
  18.                                       TDR_FormatString, message,
  19.                                       TDR_ImageType,    TDRIMAGE_ERROR,
  20.                                       TDR_Window,       pwindow,
  21.                                       TDR_EasyStruct,   &es,
  22.                                      TAG_DONE);
  23.  return nDummy;
  24. }

Re: How to use TagItem in TDR_EasyStruct ...
You should report this as a bug. For easy direct comparison I created this little test case: 
  1. /*                                                                            */
  2.  
  3. /*----------------------------------------------------------------------------*/
  4. /*                                                                            */
  5. /*----------------------------------------------------------------------------*/
  6.  
  7. 	#include <proto/exec.h>
  8. 	#include <proto/dos.h>
  9. 	#include <proto/intuition.h>
  10.  
  11. /*--------------------------------------------------------------------------*/
  12. /*                                                                          */
  13. /*--------------------------------------------------------------------------*/
  14.  
  15. 	long RequestChoice (struct Window *win,const char *title,const char *body,const char *gadgets)
  16.  
  17. 	{
  18. 	long result;
  19. 	struct EasyStruct es;
  20. 	ULONG idcmp = 0;
  21. 	struct TagItem es_tags[] = {{ESA_Position,REQPOS_CENTERWINDOW},{TAG_END}};
  22.  
  23. 	es.es_StructSize   = sizeof(struct EasyStruct);
  24. 	es.es_Flags        = ESF_TAGGED;
  25. 	es.es_Title        = (STRPTR)title;
  26. 	es.es_TextFormat   = (STRPTR)body;
  27. 	es.es_GadgetFormat = (STRPTR)gadgets;
  28. 	es.es_TagList      = es_tags;
  29.  
  30. 	result = EasyRequest (win,&es,&idcmp,TAG_END);
  31. /*
  32. 	result = TimedDosRequesterTags (
  33. 			TDR_Window,win,
  34. 			TDR_EasyStruct,&es,
  35. 			TDR_IDCMP_Ptr,&idcmp,
  36. 			TAG_END);
  37. */
  38. 	return (result);
  39. 	}
  40.  
  41. /*----------------------------------------------------------------------------*/
  42. /*                                                                            */
  43. /*----------------------------------------------------------------------------*/
  44.  
  45. 	int main (void)
  46.  
  47. 	{
  48. 	struct Window *win;
  49.  
  50. 	if ((win = OpenWindowTags (NULL,
  51. 			WA_Left,604,
  52. 			WA_Top,448,
  53. 			WA_Width,400,
  54. 			WA_Height,300,
  55. 			WA_Title,"Test",
  56. 			WA_Flags,WFLG_DRAGBAR | WFLG_DEPTHGADGET | WFLG_NOCAREREFRESH,
  57. 			TAG_END)))
  58. 		{
  59.  
  60. 		RequestChoice (win,"Requester","This is a test","Ok");
  61.  
  62. 		CloseWindow (win);
  63. 		}
  64.  
  65. 	return (0);
  66. 	}
  67.  
  68. /*----------------------------------------------------------------------------*/
  69. /*                                                                            */
  70. /*----------------------------------------------------------------------------*/
It works with EasyRequest but not with TimedDosRequester. The latter is always centered on the screen, not on the window.

Re: How to use TagItem in TDR_EasyStruct ...
First off any unused fields of the EasyStruct structure should be set to zero rather than left undefined. This can be done with "ClearMem(&es, sizeof(es));" before any other initialisation is done. Also try setting TDR_NonBlocking to TRUE in your TimedDosRequesterTags() call. If it works better this way then it's simply a missing feature in the IPrefs patched version of this function.

Re: How to use TagItem in TDR_EasyStruct ...
Just for testing sake, WPOS_CENTERWINDOW AND WPOS_CENTERSCREEN were reversed in a much older SDK. Try using REQPOS_CENTERSCREEN to see if they are reversed, too.

Re: How to use TagItem in TDR_EasyStruct ...
ok, adding ClearMem() and TDR_NonBlocking then shows requester centered on window (with REQPOS_CENTERWINDOW), but without all the eyecandy (no TDR_ImageType,TDRIMAGE_ERROR is used and buttons look '_Cancel' & 'C_ontinue' not underscored). So it's iPrefs bug then? TIA

@jabirulo
So it's iPrefs bug then?
No, just a missing feature as I said before. IPrefs patches TimedDosRequester() to use the ReAction "requester.class" when possible. The "requester.class" however from what I can see places the requester according to GUI/screen settings and allows no way of overriding this for a specific requester only.

Re: How to use TagItem in TDR_EasyStruct ...
Ok, I got the impression that 'missing feature' meant it should work but coders forgot to add code to iprefs. Shame, 'cos was a nice option could be nice on some cases.
