56 *\brief For the GtkListStore
69 * The address book is read into memory. We set up an address list
70 * containing all address book entries. Next we make the completion
71 * list, which contains all the completable strings, and store a
72 * reference to the address entry it belongs to.
73 * After calling the g_completion_complete(), we get a reference
74 * to a valid email address.
76 * Completion is very simplified. We never complete on another prefix,
77 * i.e. we neglect the next smallest possible prefix for the current
78 * completion cache. This is simply done so we might break up the
79 * addresses a little more (e.g. break up alfons@proteus.demon.nl into
80 * something like alfons, proteus, demon, nl; and then completing on
81 * any of those words).
85 * completion_entry - structure used to complete addresses, with a reference
86 * the the real address information.
