I don't have a recent cl-gtk2 on hand, but have you looked at the sample
code that comes with it to see how things should be done?

For example, if you look at gtk/gtk.demo.lisp you'll see that heights and
widths are mostly set using {height,width}-request:

    (let* ((window (make-instance 'gtk-window :title "Test pixbuf" :width-request 600 :height-request 240))

However, I couldn't find a specific DrawingArea example.  There's one in my
Black Tie library but it uses an UI designed with Glade:
