Re: help! gtk problem

[Tristan Van Berkom <vantr touchtunes com>]

        GtkContainer is an "interface" type of object.
Use the GtkFixed implementation of GtkContainer for
"fixed widget positioning" and a Gtk[VH]Box for resizables.

        Remember that you need the top parent wiget to
be a GtkWindow.
