To do that, normally you store the File.lineNumber/File.filePosition at
the location you want to generate the tag, and use initTagEntry() and
makeTagEntry() instead of simpler but dumber makeSimpleTag():

	createMyTag(qmlKind kind, const char *name, ...) {
		tagEntryInfo entry;
		
		initTagEntry (&entry, name);
		entry.lineNumber = savedLineNumber;
		entry.filePosition = savedFilePosition;
		entry.kindName = QMLKinds[kind].name;
		entry.kind = (char) QMLKinds[kind].letter;

		makeTagEntry (&entry);
	}

See e.g. Geany's PHP parser functions makeNamespacePhpTag() or
makeSimplePhpTag().
