Re: problem with auto-preview/use of new font settings in control-center

[Simos Xenitellis <simos74 gmx net>]

Dear All,
	I would like to thank
		Fatih Demir <kabalak@gtranslator.org> and
		Emese Kovacs <emese@sunserv.itp.hu>
	for their responses.

	The following act as a workaround to the affected languages.
Please will still not be able to change the basic font from the
control-panel "dynamically". Changing it from /etc/gtk/gtkrc.LL causes all
newly run applications to adopt the new font.

	The problem appears to be triggered by the /etc/gtk/gtkrc.LL
files that are provided by the default installation of
gtk+-1.2.10-ximian.10 or the most recent gtk+ distribution. Around a year
ago, there was no such problem with the default installation.
It is typical for languages not served by iso-8859-1 not to have their own
encoding for font families like
	-*-helvetica-medium-r-normal--12-*-*-*-*-*-iso8859-X
However, by manually selecting specific suitable fonts, fonts can be
changed.
For the Greek language, one can use the following /etc/gtk/gtkrc.el file:
==== /etc/gtk/gtkrc.el ====
style "gtk-default-el" {
       fontset = "-greek-helvetica-bold-r-normal-*-12-*-*-*-p-*-iso8859-1,\
		  -grinet-greekarial-medium-r-normal-*-13-*-*-*-p-*-iso8859-1,\
		  -greek-helvetica-bold-r-normal-*-12-*-*-*-p-*-iso8859-7,\
		  -grinet-greekarial-medium-r-normal-*-13-*-*-*-p-*-iso8859-7,*-r-*"
}
class "GtkWidget" style "gtk-default-el"
===========================

Similarly, suitable fonts should be able to be selected for other
languages.

To find a suitable font, you can run "gfontsel" and choose two types of
fonts that have both iso8859-1 and iso8859-X encodings. (I am not sure
whether this is compulsory, I just follow the format of the existing
file). When you click "Apply", the full font description appears on the
top text box; you copy it to /etc/gtk/gtkrc.LL

By running a new application, you can manually preview the new settings.

I am also filing a bugzilla report.

Thanks,
Simos Xenitellis
