# Usage: ./builder-children.pl
#
# This is an example of making a ListModelConcat with Gtk2::Builder (new in
# Gtk 2.12), using <child> sub-objects.
#
# The class name is "Gtk2__Ex__ListModelConcat", as usual for Gtk2-Perl
# package name to Gtk type name conversion.  The bulk of the interface is
# the ListStore sub-model bits, the operative part for ListModelConcat is
# really just that such sub-models can be made as <child> elements.
#
# The sub-models created are not wedded to the ListModelConcat.  They can be
# referred to by their id for other parts of the builder, or from
# $builder->get_object('list1') etc.
#
# See builder-append.pl for another way to do it.
