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 [1] http://lists.debian.org/debian-devel-announce/2005/11/msg00021.html [2] http://wiki.debian.org/DebianInstallerGUIFonts [3] http://lists.debian.org/debian-boot/2005/12/msg00324.html ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

some questions, please help
Hi. I have two questions: 1. How can I determine a treeview column which will GTK+'s search feature (that box that appears when starting to type) search for. 2. In the treeview tutorial (http://scentric.net/tutorial/sec-treeview-col-whole-row.html), there's a way to color a row by making a column connection to the 'foreground' property. I don't understand how to connect that signal to a column? Please help.

Re: swap images on click event.
Sorry for the delay on this, but I'm still in exams. :) When I add both GtkImages to the applet, and
run the program I get the following:
--
(xmms-applet:17352): Gtk-WARNING **: Attempting to add a widget with type GtkImage to a GtkEventBox,
but as a GtkBin subclass a GtkEventBox can only contain one widget at a time; it already contains a
widget of type GtkImage
-
When the gtk_widget_hide and gtk_widget_show functions are called, the button is hidden, but when
the other button is supposed to show, it doesn't.

Just use gtk_widget_hide()/gtk_widget_show() functions with appropriate
arguments.
}

Re: swap images on click event.
Got it working. I made an event box for each button and hid and showed each one when needed. Thanks
for your help earlier.
