Yes that would be a problem, sorry it has been a while since I wrote
this and I tried to cut and paste a little too quickly. I've added the
needed lines, inline, above. That is the code that reuses the single
widget that I talked about not showing. The first time through it uses
the GtkLayout.put method and every other time it uses the GtkLayout.move
method. Note that the widget won't actually be in the list, it will be
on top of it, obscuring a single cell of the list that is below it.
