>From a quick glance at the push-button-pane code, it looks like Mariano&#39;s suggestion of using x-spacing / y-spacing may work. If not, an alternative is to define a subclass of push-button-pane with a new compose-space method.<br>

 Hello,<br>
<br>
In order to give a project to my students using McClim for the graphical<br>
interface, I am trying to make a square button of a given size.<br>
<br>
But I always obtain a default size button the width, height, max-width, ...<br>
have no effect.<br>
<br>
Where could I find some help about that?<br>
<br>
Thank you,<br>
Irčne<br>

   :height 20<br>
   :activate-callback (lambda (x)<br>
            (setf (gadget-label x) &quot;O&quot;))))<br>
