- Date: Sun, 07 Oct 2007 17:10:13 -0400
Hi,
Sketching out an API here, prototype attached.
See also
http://mail.gnome.org/archives/gtk-devel-list/2007-September/msg00139.html
Some questions:
- in current GNOME, what are the right "parameters" to open a help
file? (i.e. what values does gtk_help_show() need to open a gnome help
file, such as document ID or anchor or whatever)
- it looks like GTK doesn't use startup notification at all right now?
There are three ways I can think of to code launching an URL from gtk:
1) have a dbus service that does all the startup notification and
other work, and invoke it from gtk
2) do all the startup notification and so forth in gtk itself, and
call xdg-open (does xdg-open support SN properly?)
3) dlopen gnome-vfs and call its code for this
- are the _with_env() flavors of these functions needed, if gtk does
startup notification itself? (gnome-vfs and libgnome have with_env
versions of url_show and help_show)
Sorry for the cross-post, but it affects both libgnome and gtk ...
Havoc
