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 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? -Alan #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 Do you want this (send t insert "Use this window for making notes" 10 10) instead of the below?
