need monospace font in zenity



Hi All,

I am using Scientific Linux 6.2 x64 (RHEL clone):

$ zenity --info --title="abc" --font "monospace 9" --text "abcdefg"
This option is not available. Please see --help for all possible usages.

$ zenity --help-all | grep -i font
<nothing>

$ rpm -qa \*zenity\*
zenity-2.28.0-1.el6.x86_64


I really need a monospaced font. I am drawing a blank on Google.
Any one know how to do this?

Many thanks,
-T
