Hi all.

I'd like to program a new gtktreemodel implementation for AF

I want to dynamically create this model data from the data returned by
any remote listing service. This listing services return, currently, a
list where each node are structures representing customers, users, etc.

We're going to implement all these current structures as g-object
"classes". All them will have a common abstract parent class called

But, for my gtktreemodel implementation I need to know, having a generic
AfDalDataNode pointer, information about its attributes (number of
attributes and their types). 
My treemodel will not have information about each actual AfDalDataNode
subclasses: it must be generic.

Can I do this? How?

If you use GObject properties for these attributes, you can call
g_object_class_list_properties (); That will return an array of
GParamSpec* pointers, which describe all the properties installed in
that object's class. If your objects implement any GInterfaces which
install properties (A 2.3/2.4 feature), you should also use
g_object_interface_list_properties(); The return values of both these
functions should be freed with g_free();

Getting the value of the property can be done via
