I success Klaas to save custom value by using DoSave but when I try to load
it again, it seems that DoLoad event is not called in my class. For checking
if DoLoad is called or not, I change my DoLoad and DoSave method that are
shown below.
void MyImage::DoLoad(wxObject* parent, a2dIOHandlerXmlSerIn& parser,
a2dXmlSer_flag xmlparts )
{
wxLogMessage("load");
// a2dImage::DoLoad( parent, parser, xmlparts );
// if ( xmlparts == a2dXmlSer_attrib )
// {
//
// faceId_ = parser.RequireAttributeValueDouble( wxT("faceId") );
// wxLogMessage("faceId load 2: %i", faceId_);
// }
// else
// {
// }
}
void MyImage::DoSave(wxObject* parent, a2dIOHandlerXmlSerOut &out,
a2dXmlSer_flag xmlparts , a2dObjectList* towrite )
{
wxLogMessage("save");
// a2dImage::DoSave( parent, out, xmlparts, towrite );
// if ( xmlparts == a2dXmlSer_attrib )
// {
// out.WriteAttribute( wxT("faceId"), faceId_ );
// }
// else
// {
// }
}
When I save my file, there is a log message for save and my custom value is
saved in CVG file successfully but when I load this file, there is no log
message for load.
