Right.
I'm ready to take on auto-completion again.
I've read the above page on GtkEntryCompletion.

What I understand ( and I know I'm mixing Perl and C stuff here ):

my $gtkcompletion = gtk_entry_completion_new ()
creates a new gtkcompletion object

my $gtkentry = $window->get_widget('my_entry');
gets hold of my gtkentry widget

gtk_entry_set_completion ($gtkentry, $gtkcompletion);
attaches the completion object to the entry object

What I can't figure, however, is:

a) How to pass the completion object a list of strings for the 
completion list
b) What the Perl equivalent of the above C functions are

Is there any documentation ( or examples ) yet on using the 
GtkEntryCompletion object from Perl?
