      <div>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).</div>
      <div><br>
      </div>
      <div>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.<br>

              No, the check-expect is fine; the definition is wrong.  As
              I recall (I don't have it in front of me), it doesn't
              actually use its parameter.<br>

            <br>
            The function is this :
            <div class="im"><br>
              <br>
              (define (width editor)<br>
               (image-width (text (editor-pre verwerker) 11 "black")))<br>
              <br>
            </div>
            As I understand your remark it doesn't use editor.  So I
            have to rewrite it so it uses the parameter editor-pre
            verwerker ??<br>

              Why do you need "overlay"?  I would think you could do
              this just with "beside" (unless you wanted to fine-tune
              the formatting).<br>

            Only beside. But how can I then take care that the text are

            something for that.<br>
