It still doesn't work. I'm using this:
(define/public (select-this-snip)
(define editor (send (get-admin) get-editor))
(define pos (send editor get-snip-position this))
(send editor set-position pos (+ pos 1))
(define w (box 0))
(define h (box 0))
(get-extent (send (get-admin) get-dc) 0 0 w h)
(send (get-admin) needs-update this 0 0 (unbox w) (unbox h)))
The snip *is* selected but not drawn as selected. The draw method
checks (pair? draw-caret) for determining whether its selected, and
this works for manual selection, i.e., left-click and mouse drag from
adjacent position.
Of course, I could work around this by maintaining my own selection
flag and resetting it in on-goodbye-event, but that seems like a hack
to me. Any ideas what I'm doing wrong?
Best,
Erich

My draw method:
(define/override (draw dc x y left top right bottom dx dy
draw-caret) (define-values (tw th tdist tvspace) (send dc
get-text-extent (get-display-name)
(send (get-style)
get-font) #t
0))
(define w (+ tw 22))
(define h (max 22 (+ th 4)))
(define background-color
(if (pair? draw-caret)
(scale-color 0.8 (send (get-style) get-background))
(send (get-style) get-background)))
(define background
(filled-rounded-rectangle
w h
#:color background-color
#:border-color (scale-color 0.8 background-color)
#:draw-border? #t))
(define c-new (send (get-style) get-background))
(define old-pen (send dc get-pen))
(send dc set-smoothing 'aligned)
(draw-pict background dc x y)
(draw-pict (scale-to-fit (get-pict)
16
16)
dc (+ x 4) (+ y 4))
(send dc set-pen old-pen)
(when (and (pair? draw-caret) (get-highlight-text-color))
(send dc set-text-foreground (get-highlight-text-color)))
(send dc set-text-background background-color)
(send dc draw-text (get-display-name) (+ x 20) (+ y 4) #t))
