Hi again, I designed an object based on gobject. I added it to an interface XML file. When loading it, The object is created, and I can use it. <interface> <object class="GtkListStore" id="list_model" > <columns> <column type="GdkPixbuf" /> <column type="gchararray" /> <column type="guint" /> <column type="guint" /> </columns> </object> <object class="BitmapList" id="bitmap_list" /> </interface> While reading the docs, I found this: In order to allow construction from a GtkBuilder UI description, an object class must implement the GtkBuildable interface. But I didn't do that. Is this an undocumented and correct behaviour, or does it work by accident? Thanks. _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
