Problems creating new environment class

[Martin =?iso-8859-15?q?Schaff=F6ner?= <schaffoe@ipe.et.uni-magdeburg.de>]

Hello,

I am in the process of writing a new environment class (to enable PDP++ to 
directly generate events in the field of speech recognition from feature and 
label files), but I stumbled across some weird problems:

I used the FromFileEnv as a starting point for writing my own HTKEnv, then 
started modifying it. Here is the (preliminary) class definition:

class HTKEnv : public Environment 
{
public:
    taFile mlfFile;
    taFile featureListFile;
    taFile entitiesFile;
    
    int transLev;
    
    virtual void ReadEvent(Event *ev);
//    void UpdateAfterEdit();
    
    void Initialize();
    void InitEvents();
    void InitLinks();
    
    void Copy_(const HTKEnv& cp);
    COPY_FUNS(HTKEnv, Environment);
    TA_BASEFUNS(HTKEnv);

private:
    HTime currentPos;
    HTime maxPos;
    
    int currentFileIndex;
    int maxFileIndex;
    
    String_Array featureFiles;
    String_Array targetNames;
    
};

Now, I'm not quite sure what the InitLinks() method is good for; anyhow, it 
does get called when creating a FromFileEnv, but not when creating an HTKEnv. 
Why is this happening?

Also, is UpdateAfterEdit the method which gets called when I press the "Apply" 
button in the Env's Edit Dialog?

Sorry for so many questions, but the project is rather large and not so easy 
to understand.

TIA,
