Unix IDL users can use this code snippet:
window,/free,/pixmap,xs=4, ys=4
device,get_fontnames=df,font='*cour*medium-r-normal*--12*'
if n_elements(df) ne 0 then dispfont=df[0]
wdelete, !d.window
to get a fixed-spaced font. I often have users run a routine which
does:
if n_elements(dispfont) ne 0 then widget_control, DEFAULT_FONT=dispfont
To get all fixed spacing fonts in session using software I've written.
