The code in question is from Spring 2001; it was last touched in revision
r3988, on 2001-04-17 .

The string "historical-quotes" is not referenced in any other file.

I'd start from scratch, using Finance::QuoteHist.

Sorry for the delay in response.

I hope that you didn't find all this too discouraging, and if you did, you'll
feel motivated to try again.

When you use a function pointer like this, you're not actually calling the
function ... you're just passing the pointer to the function for something
else (the GtkTreeModel, in this case) to invoke.  When it does eventually
call the function, it do need to pass arguments ... and it's going to pass
exactly the parameters that are expected of functions that fit the
"visible_func" signature.

The filter function only has access to its parameters; its "model" param is
generically a GtkTreeModel, but you (and the code) can assume it's actually a
GncSxSlrTreeModelAdapter.  This class has the GncSxInstanceModel that it's
adapting as the field "instances".

From a GtkIter one can get a GtkPath, which has specific indices; these
indices can then be used as list indices into the GncSxInstanceModel (and its
contained objects), to get the specific GncSxInstance that the GtkIter for a
row in the tree model corresponds to.

There is a convenience method in this file to do just those steps, taking the
model and an iter and translating it into the instance :)

GncSxInstance*
gnc_sx_slr_model_get_instance(GncSxSlrTreeModelAdapter *model, GtkTreeIter 
*iter)


Once you have the relevant GncSxInstance*, the creation state is in the
fields:

GncSxInstanceState orig_state;
GncSxInstanceState state;

...on the GncSxInstance class/struct
(see src/app-util/gnc-sx-instance-model.h:98).
