Hi all. I'd like to program a new gtktreemodel implementation for AF Architecture (http://fact.aspl.es). 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 "AfDalDataNode". 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(); http://developer.gnome.org/doc/API/2.0/gobject/gobject-The-Base-Object-Type.html http://developer.gnome.org/doc/API/2.0/gobject/gobject-GParamSpec.html http://developer.gnome.org/doc/API/2.0/gobject/gobject-Standard-Parameter-and-Value-Types.html Getting the value of the property can be done via g_object_get/g_value_get_valist. -- Peace, Jim Cape http://ignore-your.tv "It is literally true that, like Christianity, Socialism has conquered the world by defeating itself." -- Alexander Berkman, ABC of Anarchism
