A note on alignment: The `text%' class supports 'right and 'center paragraph alignment, which more or less works when the editor has a maximum width. (The docs have some caveats.)
So, you can get right-alignment to a useful degree with a sequence like this: (define tf (new text-field% ....)) ;; Make the editor have a maximum width: (send (send tf get-editor) auto-wrap #t) ;; Keep the caret visible: (send (send tf get-editor) set-padding 0 0 2 0) ;; Right-align the first paragraph: (send (send tf get-editor) set-paragraph-alignment 0 'right) I noticed that refresh wasn't right when editing right-aligned text, though, and I pushed a fix for that.
