David,
Yeh, I figured it out.
First you list your available fonts:
DEVICE, GET_FONTNAMES=fnames, SET_FONT='*'
FOREACH element, fnames DO PRINT, 'Value = @', element,'@'
then you set one up, ie:
main_text_font = Obj_New('IDLgrFont', 'Franklin Gothic Demi', Size=10)
Seems to work !!
Thanks for your help.
George.

I guess in object graphics you assign the font name
with an IDLgrFont object.

As far as I know, you can use any true-type font you have
installed on your machine:
Device, TT_FONT=1, SET_FONT='WhatEverYouHave'
There is no guarantee someone who uses your program will have
this font, however, so if we write code that is distributed,
we usually restrict ourselves to fonts distributed with IDL.
I've been using the DejaVuSans font quite a lot lately. I
like it for most things. :-)
Cheers,
David

oh, hang on - now I see you can add true-type fonts:

David,
Hmm - but doesn't that mean that object graphics only has access to Times,
Helvetica and Courier ?
Cheers

I've never heard of this being done. The object graphics system
is really set up to use True-type fonts.
