[Pharo-dev] Spec row height for list of custom widgets

[Ben Coman]

I'm trying to adapt this example from the  Spec booklet...

ListPresenter  new
  displayBlock:  [  :x  |  x  buildWithSpec  ];
  items: ('Files'  asPackage  classes
    collect:  [:cls | ButtonPresenter  new  icon:  cls  systemIcon;  label:
 cls  name]);
openWithSpec

to use my own presenter rather than ButtonPresenter, but it seems to be
only showing the first line of my presenter.  How can the height of each
list row be changed.  i.e. for the able sample code, how to make the
buttons taller?
