Help on GTK font settings
Hi
As announced [1] by Frans Pop, the debian-installer is soon going to go
be graphical: it makes use of GTK for the user interface and the
DirectFB GDK backend insead of X.
Since the debian-installer supports more than 60 different languages we
need to take glyphs from different fonts [2]: FreeSans is the "default"
font for latin alphabets, while for different languages we make use of
specialized fonts (Sazanami Gothic for Japanese etc..).
Now, one annoying issue is that, since FreeSans contains some glyphs
from some non-latin languages too (Japanese, Chinese, ...), those are
always used instead of the corresponding glyphs from specialized fonts.
It was proposed [3] that, every time the user decides to use a different
language, an appropriate entry has to be set into the gtkrc to instruct
the GTK installer to use a specific font overriding libfontconfig
preferences.
To support this, we introduced this portion of code
GdkEventClient event;
event.type = GDK_CLIENT_EVENT;
event.send_event = TRUE;
event.window = NULL;
event.message_type = gdk_atom_intern("_GTK_READ_RCFILES", FALSE);
event.data_format = 8;
gdk_event_send_clientmessage_toall((GdkEvent *)&event);
gtk_rc_reparse_all();
while (gtk_events_pending ()) gtk_main_iteration ();
(note that the GDK-DFB implementation of
gdk_event_send_clientmessage_toall() is an emoty dummy function )
into the main function of the GTK frontend of the debian installer, that
is called every time something has to be displayed to the user.
Unfortunately this has no effects on fonts-choosing: FreeSans font is
still used, no matter wha is specified into gtkrc.
Does the idea of forcing a GTK app to use a special fonts setting up an
appropriate entry into gtkrc is a good idea? and, if it is, is this
portion of code enough to make it work?
thanks
Attilio
