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 <emphasis>not</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 <literal>argv[0]</literal>.) * * Returns: the name of the program. The returned string belongs * to GLib and must not be modified or freed. */ gchar* 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); } } } #endif retval = g_prgname; G_UNLOCK (g_prgname); return retval; } I hope this answers your question. It sure helped me to answer it :)
