I would like to add a GetPrev() function and GetLast() to xml.h but I can't seem to understand how this header is setup. That is I see certain methods defined that do not have a definition to them so I would expect it to be in either a .cpp file or elsewhere. But a search on the whole Widgets folder yield no results for this function.
Basically I am trying to figure out how GetNext and GetFirst work so that I can program a GetPrev() and GetLast(). Obviously something is called SetNext but I can't find where. The same with wxXmlDocument Load. If I can see the code for this method I might be able to come up with someway to save a previous node but the code for this method is non existent. Can't find it anywhere in xml.h or in object.h or in List.h.
Does anyone know where the rest of xml.h's definition resides?
