Fonts

Fonts can be specified in the following ways (using the :font property as an example):

:font "ARIAL-BOLD-18"                             (Swing-style font spec string)
:font {:name "ARIAL" :style :bold :size 18}       (using a properties hash)
:font (font :name "ARIAL" :style :bold :size 18)  (using properties with font function)

So, you could make a monospaced text area like this:

(text :text "Type some code here" 
      :multi-line? true 
      :font {:name :monospaced :size 15})

Of course, a raw Font object can also be used.
