It looks like I've stumbled into another area where I'm lacking a basic
understanding of what's going on. I'm trying to use the built-in editor in
the gui package, but I need to put some initial content into the editor
window. When I put the following in the editor pane and run it, I get the
gui editor, but not the text. When I then
simply put the last line into the interactions window and execute it, I get
the text in the gui editor window as desired. Why? What do I need to do to
programmatically modify the text in the gui window?

#lang racket/gui
(define f (new frame% [label "Notes"]
[width 400]
[height 600]))
(define c (new editor-canvas% [parent f]))
(define t (new text%))
(send c set-editor t)
(send f show #t)
(define mb (new menu-bar% [parent f]))
(define m-edit (new menu% [label "Edit"] [parent mb]))
(define m-font (new menu% [label "Font"] [parent mb]))
(append-editor-operation-menu-items m-edit #f)
(append-editor-font-menu-items m-font)
; above pretty much straight out of the Design Doc
(define dc (send c get-dc))
(send dc set-scale 1 1)
(send dc set-text-foreground "blue")
(send dc draw-text "Use this window for making notes" 0 0)
