PrefsObject

I can load/save my PrefsObject prefs just fine....once. If I try to reload them it does not work.

Set up my application

  1. BOOL
  2. RegisterApp()
  3. {
  4. 	if (!appShowIcon)
  5. 		AppIconInfo.iconType=APPICONT_ProgramIcon;
  6. 	else
  7. 		AppIconInfo.iconType=APPICONT_None;
  8.  
  9. 	if ((appID=IApplication->RegisterApplication(PROJECT_NAME2,
  10. 		REGAPP_URLIdentifier,		PROJECT_NAME3,
  11. 		REGAPP_Description,			PROJECT_DESC,
  12. 		REGAPP_NoIcon,				appShowIcon,
  13. 		REGAPP_AppIconInfo,			AppIconInfo,
  14. 		REGAPP_FileName,			ProgramComplete,
  15. 		REGAPP_HasIconifyFeature,	TRUE,
  16. 		REGAPP_HasPrefsWindow,		TRUE,
  17. 		REGAPP_CanCreateNewDocs,	TRUE,
  18. 		REGAPP_CustomPrefsFileName,	PATH_PREFS,
  19. 	TAG_END)))
  20. 	{
  21. 		IApplication->GetApplicationAttrs(appID,
  22. 			APPATTR_Port,				&AppLibPort,
  23. 			APPATTR_AppIdentifier,		&appIDName,
  24. 		TAG_DONE);
  25.  
  26. 		AppLibSignal=PORTMASK(AppLibPort);
  27.  
  28. 		IApplication->SetApplicationAttrs(appID,
  29. 			APPATTR_MainPrefsDict,		myPrefsDict,
  30. 		TAG_DONE);
  31.  
  32. 		return(TRUE);
  33. 	}
  34.  
  35. 	return(FALSE);
  36. }

Load prefs code

  1. BOOL
  2. LoadPrefs()
  3. {
  4. 	CONST_STRPTR					StringVal;
  5. 	PrefsObject						*PrefsObj;
  6. 	struct ALPOObjIndex				oi, soi;
  7. 	int32							count, subcount;
  8. 	uint32							err, value, len;
  9. 	STRPTR							*buffer;
  10.  
  11. 	myPrefsDict=IPrefsObjects->PrefsDictionary(NULL,NULL,
  12. 		ALPO_Alloc,							0,
  13. 	TAG_DONE);
  14. 	IApplication->GetApplicationAttrs(appID,
  15. 		APPATTR_MainPrefsDict,				&myPrefsDict,
  16. 	TAG_DONE);
  17.  
  18. 	if (myPrefsDict)
  19. 	{
  20. 		Prefs->NavigationWidth=IPrefsObjects->DictGetIntegerForKey(myPrefsDict,"NavigationWidth",25);
  21. 		Prefs->ContentHeight=IPrefsObjects->DictGetIntegerForKey(myPrefsDict,"ContentHeight",25);
  22. 		Prefs->ContentWidth=IPrefsObjects->DictGetIntegerForKey(myPrefsDict,"ContentWidth",25);
  23. 		Prefs->ThumbnailPreviewWidth=IPrefsObjects->DictGetIntegerForKey(myPrefsDict,"ThumbnailPreviewWidth",13);
  24. 		Prefs->DetailsHeight=IPrefsObjects->DictGetIntegerForKey(myPrefsDict,"DetailsHeight",15);
  25.  
  26. ...a bunch more lines...
  27.  
  28. 		myPrefsDict=IPrefsObjects->PrefsDictionary(NULL,NULL,
  29. 			ALPO_Release,							0,
  30. 		TAG_DONE);
  31.  
  32. 		return(TRUE);
  33. 	}
  34.  
  35. Done:
  36. 	SAK_IOErr=IDOS->IoErr();
  37. 	SAK_IOError(Objects[OID_WINDOW],MainWindow,RequesterTitle,REQIMAGE_WARNING,0,SAK_IOErr,SAK_LocaleString(MSG_ERROR_LOADING_PREFS_FILE),SAK_LocaleString(MSG_CONTINUE));
  38.  
  39. 	return(FALSE);
  40. }

Save prefs code

  1. BOOL
  2. SavePrefs()
  3. {
  4. 	PrefsObject						*PrefsObj, *SubPrefsObj;
  5.  
  6. 	myPrefsDict=IPrefsObjects->PrefsDictionary(NULL,NULL,
  7. 		ALPO_Alloc,							0,
  8. 	TAG_DONE);
  9. 	IApplication->GetApplicationAttrs(appID,
  10. 		APPATTR_MainPrefsDict,				&myPrefsDict,
  11. 	TAG_DONE);
  12. 	if (!myPrefsDict)
  13. 	{
  14. 		SAK_IOErr=IDOS->IoErr();
  15. 		SAK_IOError(Objects[OID_WINDOW],MainWindow,RequesterTitle,REQIMAGE_WARNING,0,SAK_IOErr,SAK_LocaleString(MSG_ERROR_SAVING_PREFS_FILE),SAK_LocaleString(MSG_CONTINUE));
  16.  
  17. 		return(FALSE);
  18. 	}
  19.  
  20. 	IPrefsObjects->PrefsDictionary(myPrefsDict,NULL,
  21. 		ALPODICT_Clear,						0,
  22. 	TAG_DONE);
  23.  
  24. 	IPrefsObjects->DictSetObjectForKey(myPrefsDict,
  25. 		IPrefsObjects->PrefsNumber(NULL,NULL,
  26. 			ALPONUM_AllocSetLong,				Prefs->NavigationWidth,
  27. 		TAG_DONE),
  28. 	"NavigationWidth");
  29. 	IPrefsObjects->DictSetObjectForKey(myPrefsDict,
  30. 		IPrefsObjects->PrefsNumber(NULL,NULL,
  31. 			ALPONUM_AllocSetLong,				Prefs->ContentHeight,
  32. 		TAG_DONE),
  33. 	"ContentHeight");
  34. 	IPrefsObjects->DictSetObjectForKey(myPrefsDict,
  35. 		IPrefsObjects->PrefsNumber(NULL,NULL,
  36. 			ALPONUM_AllocSetLong,				Prefs->ContentWidth,
  37. 		TAG_DONE),
  38. 	"ContentWidth");
  39. 	IPrefsObjects->DictSetObjectForKey(myPrefsDict,
  40. 		IPrefsObjects->PrefsNumber(NULL,NULL,
  41. 			ALPONUM_AllocSetLong,				Prefs->ThumbnailPreviewWidth,
  42. 		TAG_DONE),
  43. 	"ThumbnailPreviewWidth");
  44. 	IPrefsObjects->DictSetObjectForKey(myPrefsDict,
  45. 		IPrefsObjects->PrefsNumber(NULL,NULL,
  46. 			ALPONUM_AllocSetLong,				Prefs->DetailsHeight,
  47. 		TAG_DONE),
  48. 	"DetailsHeight");
  49.  
  50. ...a bunch more lines...
  51.  
  52. 	if (IPrefsObjects->WritePrefs(myPrefsDict,
  53. 		WRITEPREFS_AppID,					appID,
  54. 		WRITEPREFS_WriteENV,				TRUE,
  55. //		WRITEPREFS_WriteENVARC,				TRUE,		// already am in path name
  56. 	TAG_DONE) != 0)
  57. 	{
  58. 		SAK_IOErr=IDOS->IoErr();
  59. 		SAK_IOError(Objects[OID_WINDOW],MainWindow,RequesterTitle,REQIMAGE_WARNING,0,SAK_IOErr,SAK_LocaleString(MSG_ERROR_SAVING_PREFS_FILE),SAK_LocaleString(MSG_CONTINUE));
  60.  
  61. 		return(FALSE);
  62. 	}
  63.  
  64. 	myPrefsDict=IPrefsObjects->PrefsDictionary(NULL,NULL,
  65. 		ALPO_Release,							0,
  66. 	TAG_DONE);
  67.  
  68. 	return(TRUE);
  69. }

The initial loads works. If I try to reload prefs, it seems to work (put in check lines to see what is happening), but it does not accept the changes I made manually with a text editor to the prefs file.

I have made sure all the ALPO_Alloc's and ALPO_Release's counts match up. Is there something else I need to be doing? It is like the "internal" dictionary is never freed and the newly loaded one does not replace what is already loaded.

I have freed the prefs array and re-allocated it before reloading. Same result.

Re: PrefsObject

What I do (in DateTime.docky) is:

  1. ...
  2. uint32 ReadXMLcfg(char *filename, struct DockyBase *db, struct DockyData *dd)
  3. {
  4.  PrefsObject *dict;
  5.  uint32 err;
  6. //IDOS->Printf("[XML]Loading '%s':\n",filename);
  7.  IExec->NewList(&listbrowser_list);
  8.  
  9.  dict = IPrefsObjects->PrefsDictionary(NULL, NULL, ALPO_Alloc,0, TAG_DONE);
  10.  
  11.  err = IPrefsObjects->ReadPrefs(dict, READPREFS_FileName,(ULONG)filename, TAG_DONE);
  12.  if(err)
  13.  {
  14.   IUtility->SNPrintf(loc_buffer, 256, GetString(&li,MSG_WARN_READING_XML,db),err);
  15.   DoMessage(loc_buffer, REQIMAGE_WARNING, db, dd);
  16.   err = 0;
  17.  }
  18.  else
  19.  {
  20.   PrefsObject *mydays1 = IPrefsObjects->DictGetObjectForKey(dict, "My Days");
  21.   PrefsObject *mydays2 = IPrefsObjects->DictGetObjectForKey(dict, "Month-Day-String-Cmd");
  22.  
  23. ...

Don't you use 'IPrefsObjects->ReadPrefs();' for (re)reading xml file?

Re: PrefsObject

That fixed it. Strange it doesn't require that for the first reading. I built my code from examples on Hyperion forum. I probably had it in there originally, but since it worked the first read without it I took it out. I didn't need to reload the prefs until recently.

Thank you!
