That's also a possibility.

I think we'd need two callbacks similar to:

void (*var_attribute_added) (struct dictionary *d, int var, const char *attr_name, void *aux);

void (*var_attribute_deleted) (struct dictionary *d, int var, const char *attr_name, void *aux);

The "int var" parameter might not be needed, but all the other call backs have it ...

It really doesn't sound ideal to put this in struct dictionary, since most struct dictionary clients have no interest in it.  To me, it sounds like a better idea to put it in an auxiliary structure that PSPPIRE maintains (I think that we have PsppireDictionary or some such object) and update it from a callback when something changes.

If we don't have all the necessary callbacks for this then I'd be glad to add them.

It certainly sounds like a reasonable option.

In order to make this possible, the dictionary needs an additional structure which will contain the union of all the sets of variable attribute names for all variables in that dictionary.  This structure also will need to be indexable by integer value.

I suggest that Ben's abt structure containing reference counted elements would be the way to go.   Does anyone have any better suggestions?

The GUI's variable sheet should display and allow editing of the VARIABLE ATTRIBUTES.
