Well, I gonna love you, you just give a light!
Thanks a lot!

Here is it:
1, What is the default title of a GTK window? I mean, if there is no
string
was assigned to title of a GTK window, what will be exposed in the title
bar
of said window?
I got curious so I looked. All three implementation Win32, X11, and my
favorite Quartz (Next Step, just cause that's what I'm working on now)
implements gdk_window_new based on the underlying platform and are
somewhat different. From what I can gather this is the part that gets the
title and use the implementation specific library functions to set the
actual title, with the text coming from this tidbit of code based on glib:
in gdk_window_new_internal(){
(implementation specific code)
if (attributes_mask GDK_WA_TITLE)
title = attributes-title;
else
title = get_default_title ();
(implementation specific code)..
}
with the function get_default_title defined as:
static const gchar *
get_default_title (void)
{
const char *title;
title = g_get_application_name ();
if (!title)
title = g_get_prgname ();
return title;
}
in all implementation, thus the answer being, the executable name.
2, Whether there is another interface for developers on setting title on
GTK
window except gtk_window_set_title?
I suppose you could use g_set_prgname() look at
http://library.gnome.org/devel/glib/unstable/glib-Miscellaneous-Utility-Functions.html
3, More specifications, will GTK framework take application name from
anywhere and set it as title into any untitled window in the application?
That all. Thanks alot.
Take application name from anywhere? Huh? I can't say the function below
is straight forward, I can only imaging its convolution is do the WIN32,
but from what I can gather g_prgname is a global variable within the file,
and as as mentioned initialized in gdk_init. Actually it comes from
g_option_context_parse() in goption.c.
Basically the function (very compiler depended) finds the program name and
sets it, which intern becomes your very changeable window title.
**
* g_get_prgname:
*
* Gets the name of the program. This name should emphasisnot/emphasis
* be localized, contrast with g_get_application_name().
* (If you are using GDK or GTK+ the program name is set in gdk_init(),
* which is called by gtk_init(). The program name is found by taking
* the last component of literalargv[0]/literal.)
*
* Returns: the name of the program. The returned string belongs
* to GLib and must not be modified or freed.

g_get_prgname (void)
{
gchar* retval;
G_LOCK (g_prgname);
#ifdef G_OS_WIN32
if (g_prgname == NULL)
{
static gboolean beenhere = FALSE;
if (!beenhere)
{
gchar *utf8_buf = NULL;
wchar_t buf[MAX_PATH+1];
beenhere = TRUE;
if (GetModuleFileNameW (GetModuleHandle (NULL),
buf, G_N_ELEMENTS (buf)) 0)
utf8_buf = g_utf16_to_utf8 (buf, -1, NULL, NULL, NULL);
if (utf8_buf)

g_prgname = g_path_get_basename (utf8_buf);
g_free (utf8_buf);
}
}

retval = g_prgname;
G_UNLOCK (g_prgname);

I hope this answers your question. It sure helped me to answer it :)
