Drawing area color weirdness help?

["Andrew P. Lentvorski" <andrewl deliverator io com>]

Okay, I created a set of widgets and packed everything together.
One of the widgets is a GtlDrawingArea.  Fine.  I attach the expose
event to the callback function at the bottom of this message.
Everything comes up fine.  It even creates a nice red rectangle.
Then I resize the window ... urp ... the color in the GtlDrawingArea
changes to a random color every time I resize it.  Yellow .. Green ...
Blue ... you name it.  No particular rhyme or reason.

Why?

I'm assuming that I'm doing something wrong, but I have no idea what.

Also, how do you create a GdkColor from an RGB value?

Thanks,

Expose callback function starts here:
static gint
wave_expose_event(GtkWidget *widget, GdkEventExpose *event)
{
  gint width,height;
  GdkColor foreground;
  GdkGC *mygc;

  if (!gdk_color_parse("red",&foreground))
    {
      fprintf(stderr,"Failed to parse color\n");
    }

  gdk_window_get_size(widget->window,&width,&height);

  if (!(mygc = gdk_gc_new(widget->window)))
    {
      fprintf(stderr,"Failed to allocate GC\n");
    }

  gdk_gc_set_foreground(mygc,&foreground);

  gdk_draw_rectangle(widget->window,
		     mygc,
		     TRUE,
		     0,0,
		     width,height);

  gdk_gc_destroy(mygc);

  return FALSE;
}
