Element ID and other old Properties

Anonymous — Tue, 04 Oct 2022 14:49:38 GMT

I have quite a simple question. But I really could find a simple solution in the documentation. I have check Element and Memo structure and it's not there.

I would like to access element ID and also other Properties which are older than properties like: structural function, position. How can I do it?

Hi,
The element id is elemInfoString in memo.You can find what you want in the Do_DumpElem function in the Element_baseic.cpp

Thanks a lot, I would never found it out Do you have any clue how to access other parameters like position, structural function?

I mean time I did a workaround and put ID into the property with an expression. Probably we will do it with other properties and kind of skip using those old props.

Hi,
You can see this in Element_Test example.


// -----------------------------------------------------------------------------
// Dump element category value
// -----------------------------------------------------------------------------
void		Do_DumpElemCategoryValue (const API_ElemCategoryValue& elemCategoryValue)
{
	WriteReport ("   %s   : %s (%s)", GS::UniString (elemCategoryValue.category.name).ToCStr ().Get (), GS::UniString (elemCategoryValue.name).ToCStr ().Get (), APIGuidToString (elemCategoryValue.guid).ToCStr ().Get ());
}


// -----------------------------------------------------------------------------
// Dump element's categories
// -----------------------------------------------------------------------------
void		Do_DumpElemCategories (const API_Guid& elemGuid, const API_ElemTypeID& typeID, const API_ElemVariationID& variationID, bool dumpDefaults)
{
	GSErrCode			err = NoError;

	GS::Array<API_ElemCategory> categoryList;
	ACAPI_Database (APIDb_GetElementCategoriesID, &categoryList);

	categoryList.Enumerate ([&] (const API_ElemCategory& category) {
		if (category.categoryID != API_ElemCategory_BRI) {
			API_ElemCategoryValue	elemCategoryValue;

			if (dumpDefaults) {
				err = ACAPI_Element_GetCategoryValueDefault (typeID, variationID, category, &elemCategoryValue);
				if (err == NoError)
					Do_DumpElemCategoryValue (elemCategoryValue);
				else
					ErrorBeep ("ACAPI_Element_GetCategoryValueDefault ()", err);
			} else {
				err = ACAPI_Element_GetCategoryValue (elemGuid, category, &elemCategoryValue);
				if (err == NoError)
					Do_DumpElemCategoryValue (elemCategoryValue);
				else
					ErrorBeep ("ACAPI_Element_GetCategoryValue ()", err);
			}
		}
	});
}
