Subject: Re: setting background color on gnomecanvas widget

For now, I'm just putting a colored Gnome::CanvasRect as the
background and resizing it when the canvas gets resized.

Couple more questions:

1)  Can someone point me to any programs that use ruby's gnomecanvas? 
(besides Sokoban and that one Chess Clock one)

2)  I'm drawing a bunch of lines on a GnomeCanvas that's supposed to
be a grid.  The user can specify the grid spacing (in pixels), and can
also resize the Canvas (so more grid lines need to be drawn).  What is
the standard way to redraw all those lines when the user specifies a
different grid spacing frequency or when the user resizes the canvas? 
Put them all in a CanvasGroup and then delete and recreate all the
lines in that group on every resize and redraw?

Thanks,
Joe
