I should have given a better explanation of what I'm trying to accomplish. I'm trying to create an outline/template for taking notes during the execution of a program, Most of the contents of the window will come from the user either by typing directly or by copying and pasting from information provided by the program, hence the desire to use an editor-canvas%. Your earlier suggestion to simply use
(send t insert "Use this window for making notes" 10 10) to initialize the editor-canvas% works fine for this purpose, but a canvas% doesn't. I have some notion of later being able to modify the content/format of such an "Intelligent Notepad" dynamically, but I'm not there yet either in terms of overall design or of understanding how to use the gui to accomplish this. Thanks for your help. _____ From: Matthias Felleisen [mailto:[email protected]] Sent: Saturday, September 21, 2013 6:40 AM To: Alan Johnsey Cc: Racket Mailing List Subject: Re: [racket] Using GUI editor Robby means something like this: #lang racket/gui (define f (new frame% [label "Notes"] [width 400] [height 600])) (define my-canvas% (class canvas% (super-new) (define/override (on-char . x) (displayln x) (define dc (send this get-dc)) (send dc set-scale 1 1) (send dc set-text-foreground "blue") (send dc draw-text "Use this window for notes" 10 10)))) (define c (new my-canvas% [parent f])) (define t (new text%)) (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)
