Is there a way to scale the font for widgets (i.e button labels) with
the motif interface?

thanks,
:-) marc

Not so, Martin! XFONT has worked on VMS since '92 ...

So it seems, the only way to control the fonts is to set them
explicitely and store them either in some UValue field of the widget
or use object oriented widgets where you should be able to

thewidget->SetProperty, defaultfont=defaultfont

and redisplay. You can then try to apply some arithmetics on
defaultfont to choose a somewhat larger yet related font for the
labels (or you just set this explicitly as, say, labelfont). In order
to please Pavel who will want to run it on a Mac, too, please make
sure that your solution works for all platforms. In a recent program
by David (with a little influence of myself ;-) we use the following:

; Set widget font names.

thisOS = StrUpCase(!Version.os_family)
CASE thisOS OF
'WINDOWS': BEGIN
IF N_Elements(labelfont) EQ 0 THEN self.labelfont = 'Times*Bold'
IF N_Elements(defaultfont) EQ 0 THEN self.defaultfont = 'MS Sans
Serif*10'
END
'MACOS': BEGIN
IF N_Elements(labelfont) EQ 0 THEN self.labelfont = 'Times*Bold'
IF N_Elements(defaultfont) EQ 0 THEN self.defaultfont =
'Times*10'
END
ELSE: BEGIN
IF N_Elements(labelfont) EQ 0 THEN self.labelfont =
'-*-times-bold-r-*-*-12-*'
IF N_Elements(defaultfont) EQ 0 THEN self.defaultfont =
'-*-times-medium-r-*-*-12-*'
END
ENDCASE
Widget_Control,
Default_Font=self.defaultfont

This only works if the widget is currently not realized.

Cheers,
Martin

PS: By pure chance, I recently discovered IDL's xfont utility.
Apparently it only works for Unix platforms, although it shouldn't be
too hard to write a tool that would be platform independent.

As far as I know, there is no way to get at this
information programmatically. IDL is picking up
system font information. I can change various
fonts by playing with the Appearances/Font
properties on my Windows machine, but so far not
the font that is used for most things in widgets. :-(

Cheers,

David
