Re: gtk3 (GtkTextView) and MacOS

[Jim Charlton <charltn gmail com>]

Roger:

I tried your font changing solution to alter the font for my gtk3 
application.  I was unable to change the font by putting gtk-font-name 
in settings.ini regardless of where I put that file or the value of the 
environment variable XDG_CONFIG_HOME... or the actual font name.  I 
found this to be true on both MAC OS X (Yosemite 1010, Gtk3 and Gtkmm3 
built with jhbuild) and on my Linux Ubuntu box.

I can change the font for specific widgets, as I mentioned previously, 
using the override_font method of  Gtk::Widget in Gtkmm.

This is not an actual problem for me as I like the fonts that I am 
getting.  But I just thought that I would mention that there is still 
some magic going on that I, for one, do not understand.
