# Usage: ./builder.pl
#
# This is an example of making a ListModelConcat in a GUI with Gtk2::Builder
# (which is new in Gtk 2.12).  The class name is
# "Gtk2__Ex__ListModelConcat", as usual for Gtk2-Perl package name to Gtk
# type name conversion.  There's nothing builder-specific in
# ListModelConcat, it's all inherited from the usual builder widget
# handling.
#
# The builder can create the underlying GtkAdjustment object too, though
# note that the <property> setting of the initial "value" gets clamped to
# the upper/lower range and so generally the value should be set after upper
# and lower.
