Drawing in a Container

["Dustin Moore" <me dustinmoore net>]

Hello,

I have made a custom widget from a Container object that
draws a border and colors the background behind a single child widget. 
It works just fine as long as I only use it once in a window, but if I
put two or more instances of the widget in a table, the child widget is
not visible in all but the first instance.  I have a feeling it has
something to do with sharing the same parent window, but nothing I do
seems to help.  I have attached a modified version of a gtkmm example. 
The custom widget is a marriage of the two examples from Chapter 25 of
the gtkmm book.

Any help would be appreciated,
