Only beside. But how can I then take care that the text are
displayed into the empty-scene. I think you need overlay or
something for that.
Every image function returns an image, so you can use beside to
create an image of your text with the cursor in the right spot, and
then place that image in your empty scene however you want (you used
place-image, which would work, but I would suggest place-image/align).
In general, I would suggest (as HtDP does) that you experiment with
each piece of the image in the interactions pane, and then experiment
with composing them until you get what you want. For instance, use
the interactions pane to try to get the text and cursor together
using different image functions until you like what you get, then do
the same with composing that result and the background.
I have problems with place-image/align.
I have this :
; Editor -> Image
; Function which displays the struct on the screen into a image.
(define (render verwerker)
(place-image/align (beside (text(editor-pre verwerker) 11 "black")
cursor (text(editor-post verwerker) 11 "black")) 0 0 left center
workspace ))
But now I get a message that left is out of context.
But where do I put it then ?
